Mate if you want rock solid to the point of absolutely no motor vibration and truly the end of the dyna wobble then do as I did..research the Kinetic motor mount for dyna v twin,this is totally innovative this will eliminate any vibration I mean any !and this coupled with the true trac system absolutely rock solid Honestly mate look it up you won’t be disappointed bro regards Lozza
Bingo ! You solved it for me....the fork legs can move slightly up / down but not totally true to square--i.e. the front wheel can wiggle out of vertical. Started by the bump at centerline--knocks the wheel out of vertical. Needs a stiffer 'squaring' clamp on axle, or retrofit a squareness brace on upper end of legs.
I fixed the wobble in my dyna with BBC motor mounts and front and rear legends shocks; plus fork brace and roaring toyzz swing arm. Now it handeles like a sport bike. Salud ! For the dyna fans from colombia South america
@@milanmills-zikmund597 no, putting a bandaid on an issue covers it up...it doesn't fix the cause of the wobble...... A bike should not need a stabilizer at 75mph.....
This is not just a Dyna problem. It's inherent in most Harleys. I had a 2009 Road Glide that gave me the wobble severely more than once.I also bought a 2021 Street Glide that has given me this issue. I took it in for a check and they said they tightened up the front end (whatever that means). Anyway, it is a known problem with Harleys and "can" be fixed by buying more after market stuff that will resolve the issue. Now, I'm no expert, that I'll admit up front. But I've been riding since I was fourteen and now I'm sixty one. I've ridden many, many bikes Harley's, Honda's, Yamaha's, Kawasaki's, BMWs etc,etc. This is a known problem endemic to Harley Davidson motorcycles I just don't know why Harley doesn't fix it. Period. ( and then you wonder why they can't sell their bikes to a younger crowd?) I love my Harley, don't get me wrong but HD does stand for Hundred Dollars coz every time you bring it in for maintenance...even under "warranty" well, you know.
Yamahas are also notoriously known for bad head bearings that cause this. The only company that has a 100% fix from factory is Ducati. They implemented some type of counter gyro into the crank.
My 13 wide glide has been doing this since 6000 miles, the dealer had it several times and couldn't fix it. Well they fixed everything but the problem. It dont do it at all when riding 2 up!
Never had a wobble owned 36 motorcycles including a RK and Sportster , I have a 2009 Vstrom with cupped tires it's hands off at 80 mph gets 66 mpg and is comfortable of course it's not a Harley but I love it
I dealt with it by changing the guts out of the forks and replaced with Emulators and heavier oil, put a True Track set up on, and changed out the shocks. HD actually told me to just drive at the speed limit. 35k miles all is good now.
My dyna never wobbled. 2012 fxdb legends front and rear. I did a mag conversion now it wobbles. The mechanics logic was I've lost the flex of spokes that was absorbing the wobble. Now I have straight solid mags and I'm getting the wobble. Apparently my engine mount is shot. He suggested I get the front mount and swing arm bushings replaced since I'm under warranty. He also suggested an engine stabilizer. I'm so stressed out. If I can't safely place my bike where it needs to be on the highway or blast high-speeds in a straight line my dynas useless. I pack ride and go the distance. Ride quality is poor now. When there's something wrong with my bike, my world seems to crumble. Super depressed.
Ive had this issue as well with my 2012 Dyna. I tried everything, spent over 4k with suspension and got rid of spoke wheels and got a stabilizer etc. I still wasn't happy at the end of the day and sold the bike after I realized how much money I spent on a 96 cubic inch harley with 86 horse power or so. I think its stupid how much money we dyna guys have to spend to make "Harleys performance line up ..the dyna" actually preform hahaha. I love Harleys and always will. they are awesome however I am looking at other options out there like a BMW s1000xr. Rode one and it felt like how I always wanted my Dyna to ride. Just my 2 cents, not knocking Harley or the Dyna, I am just disappointed. Good video btw.
If I let my steering stem nut get too loose, I'll get the shakes as well. I have new springs and heavy oil up front, and it makes a difference as well. If ya got the shakes, check the alignment, spokes if ya got em, tires, and steering nut. For the record, I had a similar problem on a ZX7R - so it's not just an HD thing.
There is only one thing worth remembering - fit engine mounts (front and rear) from Big Bear Performance and ALL the handling issues are solved . My '10 model Dyna - tricked out to over 120 bhp and torque with a 113" engine - was transformed in the handling department !!
They should come from the factory with a frame and suspension set up that’s wobble proof. It’s the 21st Century, no excuse for shoddy engineering. Lots of bikes have dual rear shocks and rubber mounted engines and do not wobble.
@@admiralbeez8143 Totally agree with you there mate - the Dyna mounts are just crap and they decay so fast. Harley say to inspect and replace them when necessary but I found they needed repalcing at 10,000 miles as they are just soft rubber and not fit to handle all the weight of such a bike.
Dyna wobble is absolutely a thing and caused by an inferior designed engine/trans/swing arm mount system and suspension. This happens both at high speed cornering and straight line high RPM running. The vibrations from the unbalance motor get transmitted through the swing arm and tire. All the things mentioned such as tire pressure, tire wear, and fork oil will alleviate the symptoms a bit but what will cure it is performance suspension AND performance motor mounts front and rear. HDs aren't made to ride as hard as people are riding these days from the factory. They are all pretty much entry level bikes on the showroom floor. Stock sucks. Buy used and upgrade!
For anyone reading and watching, please let me make a tire suggestion. Over the years I have experimented with most all brands of tires. My go to tires are the MICHELIN COMMANDER 2, and my personal Dyna gets ridden quite aggressively, not abused, but ridden. Unfortunately the tires I dislike the most, are the ones I change out the most, and that's the Dunlop D402, with the HARLEY DAVIDSON on the sidewall. The K591 MIGHT be a better option, but I refuse to try them, or waste my customers money on them. 🇺🇸🏍🇺🇸🏍🇺🇸🏍🇺🇸 Remember folks, if you change tires from stock, USE THE RECOMMENDED TIRE PRESSURE BY THE MANUFACTURER, NOT the recommended pressure in the Service Manual.
My 2003 Dyna low rider same thing. The rubber motor mounts are crap. I replaced them with new ones, new tires, trued the spokes, new fork seals and springs got an alignment nothing work. Finally put front and rear stabilizers and no more motor bouncing up and down while frame going left to right. I would suggest doing the same. Good luck to ya.
Was your swing arm bushing and bearing worn out? Usually when those wear out they cause excessive wear and tear on your rear motor mount and that combination can also cause a real bad handling issue. Glad to see your handling problems are over. I'm also glad to hear a dealership stepped up to help you with this. Out here they normally won't add on an aftermarket stabilizer link at the rear motor mount. Glad it worked for you. Have a good ride.
Only the motor mounts were worn. I bought it used 2 years ago with only 6k miles on it. Now only has 14k would've been more but this wobble took a few moths to finally solve the mystery. Yes the mechanic at Harley is a friend of mine so that may have helped me :)
Fork braces, and when trying to hold bars steady, I loosen my grip and it gets better, trying to hold it from oscillation is difficult due to not being stable sitting on a seat and wobble just transfers to your upper body then you have an opposite frequency causing what is similar to oversteering, I found that almost lightening up on grip helps in my situation but is also dangerous if experimenting.
It is normal for the dyna to wobble a bit, because the rear swingarm is bolted to the transmission case, and a rubber mount to the frame so that's where the wobble comes in, also you do initiate it more when you put a death grip on the bars, but a wobble like that in a straight line can mean the neck bearings are loose
Thats not why it did it. You have less control with forwards. Motor mounts, swing arm bushings, tire pressure/balance/tread, steering head torque aka "fall away" And suspension are what cause wobbles.
I know right off the batt best way to fix that is adjusting your head tube bearing tension make sure your triple trees are clamping with proper torque. Then get that solid transmission mount for the wheely game.
Forks out of alignment was the problem with my 07 Dyna SuperGlide. 2000 miles later and I've had no issues what so ever and I cruise at 80 mph all the time.
I have the speed wobbles. Try true track first. I’ve changed almost everything on my Dyna but stabilizer. I say try true track first because I’ve tried everything else. I have Big Bear choppers front and rear motor mounts and wobble is still there and so much vibration that I can’t even ride the bike. All new front end suspension, bearings, racers, stupid fall away, tires, and rear suspension. I’m taking big bear front mount out and replacing with new original mount and true track. I’ve tried almost everything for this wobble and I’m hoping that true track finally fixes this nightmare
Dude good video! I'm watching your video, listening to what you're saying and suddenly realized where you're riding at. Weird seeing an area I live in on the tube. Thanks for the video, gotta do some aftermarket work. HD makes a good product, aftermarket makes it a better product.
I've never had wobble I run good tires professionally installed. I check air pressure every week, front goes down slowly, I have to air it every 2 weeks. And it's done this for years. If guys have wobble you have something wrong. A university in England did an extensive study on wobble its on RUclips every rider should watch it. Education may save your life.
hey! My motorcycle Dyna 2010 FXDC has a lot of vibration, and I hear you say when you bought your motorcycle that your motorcycle also had a lot of vibration. I installed a new Front Motor Mount and a stabilizer. my tires are good. my suspension is good. what did you do to get rid of the vibrating? greetings from Belgium
It doesnt happen to me going 100 mph i just muscle through i tear it up in the canyons too. I have gotten rear steer i never fight it just keep the throttle steady and GENTLY apply rear brake it fixes itself. Alloy art combi stabilizer kits help
Those are controllable. If you get the real wobbles, there is no stopping it, no throttling out. You just start praying. It's something else. It happened today.
From a guy who fixed his wobble: “These older models with the 39mm needs more stabilization. I have the GPR and a fork brace and it killed my wobble. Also, neck bearing, and front and rear motor mounts. Replace all that with brand new stock Harley ones and it goes away.”
people wheel stand these machines and this hammers the hardened bearings into the hard raceways. this pits and damages them adding to loseness and a wobble as well. this applies to any street bike
It could be anything from tire pressure, loose spokes, miss-aligned engine/swingarm to frame, Fall away adjustment, worn out motor mounts or worn out swing arm bearing and bushing. Feel free to contact me if you have any questions.
I wouldn't worry about wobbling. The way you are riding you're not long for this world. One of those four or more wheeled vehicles will close the door on you eventually.
U should have a steering stabilizer on there but what’s probably causing that is ur rear wheel is out of alignment, need to be perfectly straight in the rear and u won’t get this, plus new front and rear tires would help too
I got a fork brace on my 14’ dyna wife glide and it made a big difference in the way it handles... might of made the steering input a little too sensitive... not sure on the effectiveness of alleviating wobble tho... I never rode hard before I put it on so I don’t have anything to compare it too
predator front mount a new fact rear and keeping under 80 your fine these were never made to ride over 55 60 mph the tech is 1980s including the biased heavy tires. incase your not aware they also bias the weight on the rear wheel so leaning forward and placing more on the front tire also helps. but the predator mount was worth every dime they charge.
Great video. So the tires are 29 PSI front and rear now and there is no more wobble? Or did increasing tire pressure to 38 PSI rear and 32 PSI front sort it out? Thanks
I had the same problem. The rubber engine mount are soft-losse because there are not new and that is the wobble. The problem is if you put stiffer mounts its gonna be better but you will get more vibrations. First ride on my bike and I didn't like that rubber feeling between my and road, plus the wobbles... The first month I was more reading on internet than driving the bike lol. If I know that before I will buy only softail. The feeling is like driving saab 9-3. What help fix this wobbles and also get rid of that rubber feeling is to put front and rear stabilisers. No wobbles and the feeling is 90% of full frame bike what is all bikes on the word except this hd lol... BTW the wheel alignment doesn't help because you have only 2 wheels then they cant have problem. Yes the body of the bike will not be straight-parallel with wheels but the two wheels will be always parallel between to other. You can not make two wheels unparalleled at all because then you actually turning. One more thing- I also did put fork brace and yes helps a lot. The bottom of the fork is bad bad. The axlebolt where is attached to the fork all that mount is weak. It is actually looks like joke that two screws on the right fork what is hold the axelbolt. Any another bike has clamp on that bottom.
There's a kit to put a heim joint on the front engine mount to keep the engine and trans in the same plane as the rear wheel. But he should have that wobble at that low of speed. Is his front engine mount loose or needing replacement? Did he check his wheels vertical alignment with magnetic angle finder and use the top engine mount heim joint to adjust?
Sir, I have a small Dyna only performance shop, and I am not going to sit here and guess the issue or all the issues with your bike, but that being said, you Sir have some very serious problems there. Shaking like that at only 70-75 is significant. Have it checked out by someone who knows, please. My daily driver has almost 80,000 miles, and I spend a fair amount of time at dragstrip with it. It doesn't shake.
My Fatboy does the same thing anytime I hit past 90mph I have 16 inch apes on mine but even before the apes I had the issue I’ve just gotten used to it and now being in a small town in the middle of nowhere it’s a non issue but it definitely sucked on the cross country trip I made
A list from greatest cause to lesser causes of wobble , loose or worn out neck bearings, loose or worn swing arm bearings, loose or worn wheel bearings , worn tires , incorrect pressure , out of balance wheels , worn suspension components, loose motor mounts, or rubber vibration isolators , weight distribution..At the Toronto bike show , between 1978 & 1980, BMW took their largest displacement bike, & (on a closed course in a straight line), put a single 15 to 20 pound weight on it, & shifted it from the back of the bike forward, & then in different locations that drivers would normally carry weight .This was to imitate adding a fairing or luggage etc .The bike developed a near tank slapping wobble at 86 mph ! Consider that it was a new bike on a closed course ,& that it cost twice the price of the same displacement japanese bike!.. Koodos to BMW for having the guts to show the truth ., & show the reality of possible causes..
Hi Crash. Where are you located? I can eliminate that wobble. The Straight Shooter will locate the problem and we can make that bike handle like it's on rails. The video shows the engine/swing arm is out of alignment. There is more tension on one shock than the other, causing a handling issue. I eliminate harley wobbles all day every day!
@@markmorris2336 I'm in Rancho Cordova, just outside Sacramento California. I wish I had a shop out there to send you to but it doesn't seem like shops out there are concerned about eliminating the wobble. The closes one to you is either Browns Cycle in Dallas Texas or Cycle Tech Industries in Hurricane, Utah. Or you can email me and maybe I can help you out.
@@RackandPull thanks for mentioning Brown's Cycles. They're 25 minutes from me and after doing new tires, wheel bearings, Sputhe Positrac Stabilizers,and front and rear suspension on my 2016 FXDLS this weekend I think professional alignment is the last step in making my dyna handle like a dream.
@@RackandPull hi Rack and Pull any shop recommendations near to San Jose California I have the same problem every time on 75mph to 80 mph (and not problem with someone up... past 80 mph )
Seems like a front tire out of balance problem. Then I'd suspect neck bearings. But yea tire pressure and balance. I was at the sand dunes with my tw200. To get through the sand I let pressure out of the rear. It was fine. Then I figured let air out of the front tire. I go going and immediately fell off the bike.
Motorcycle tires bleed air. You should be checking pressure weekly. I run 40 rear and 38 front on my RK. I have been riding at speeds up to 108 and never had an issue.
Honestly, if the intent is to make videos, then the smoked windshield has got to go. It's both a visual obstruction and the focal point of your video. A clear screen might not represent as well aesthetically, but the choice is going to have to be one of process... HOW do I frame my shot, HOW do I maximize the visual appeal of my content? Versus how do I make my bike look sick. You dig?
I've got a street Bob with 40k miles. Ridden like I hate it constantly. Front motor mount is most definitely shot and probably the rear as well. Cheap mismatched shinko tires, and static balanced wheels with fishing weights. And super tall T bars. It had a head shake problem at 15k and I replaced the neck bearings and torqued them to 90 ft pounds because of the Harley under torque problem. I can ride it at triple digit speeds with no crazy sh#t like that.
I just hit 40k not to long ago and i'm pretty sure I need neck bearings. Bars straight dead on it feels a little loose in the front. Move them just a hair left/right and it feels nice and tight.
Eric McGraw you most certainly did NOT torque the steering head bearings to 90lbs, the stem wouldn't turn then. You must be confusing the crown nut with the bearings. The bearing adjustment is a touch over hand tight.
After spending that kind of money on a bike you shouldn't have to do anything to the damn thing for it to ride like its suppose to. Harley is still way behind on mechanical technology
Bike is ridden well beyond what Harley ever intended which is a big part of why this issue happened the first time. In this specific case though, the problem ended up being tire pressure.
they're not behind on technology, they're ahead on building crap to fail and having it come intot the dealership for repair. Victory hasn't once had to warranty a motor, last i heard. which is probably why they're not doing so great...
condor 408 - agreed! I had a quarter fairing on my Dyna and made the wind factor worse! Took it off, now riding at fast speeds is a breeze without it 💯
@@saulpaul7263 Hmmm. interesting. I have a street 500 and I noticed the other day when I took it around 75-80 I got the wobble and I do still have my headlight fairing attached.
Frankies World the street 500 and 750 were never designed to go super fast on a highway there inner city bikes so I wouldn’t expect it to be able to handle 80+mph without some modifications.
I’ve ridden plenty of Dyna’s that rip smoothly over 100mph - That’s just something wrong with your bike. Improper maintenance. Could be a million things from worn neck bearings to improper wheel balance.
Shit tire pressure, the tire itself, speed and your weight. Now you know why they stopped making the Dyna, and the pre-2009 touring frames. You slowdown the wobble stops
I installed Progressive 444 shocks & Alloy Art Combi Stabilizer Kit on my '08 fxdb and I have 16" apes, the stock shocks suck. Similar issue on turns but I feel it comes from the forks, just don't think they stay perfectly parallel on bumps in turns. Only thing I can think of is get inverted forks if you can afford em. These bikes were never designed for turns I guess either way I twist the throttle and all worries go away.
444 aren't the greatest but should be much better than stock. It wasn't until after I did the rear shocks that I realized how bad the front end was. Terry cable has got dampening rods to help or race tech has got some stuff aswell. Hands down an inverted front end would be killer but there are other mods that can be done for much cheaper to get the bike to handle better.
In my 2016 I have the 12.5" 444s in the rear and up front the Progressive Monotube systems. It's WAY better than stock but I wish I knew about Legend Suspension and Racetech before I bought them. Inverted is better but you can build an awesome front end with parts from Racetech for a lot cheaper that will perform pretty close to the same on the street. RWD is entering the market with shocks too.
Bull shit. My 2009 fatbob Dyna has no wobble what so ever. Solid and I rip the thing with stage 4 over 120 mph..He has something wrong with his bike. Tire out of balance, fork or something.
I stopped watching at "I dont know if there is a true fix for it"..... Suspension. Suspension. Suspension. Harley suspension is notoriously shit, any aftermarket high quality suspension, set right, is going to eliminate this and make the bike stable at 140+.
What i can't stand is his unsafe passing, guess he thinks he can die twice. Legal or not, it stupid to pass on the right or within 12"s of cars. Not observing safe following distance, cutting in on people without any space for them to brake......it's a recipe for death. At least he got to there a few minutes faster.

I know right off the batt best way to fix that is adjusting your head tube bearing tension make sure your triple trees are clamping with proper torque. Then get that solid transmission mount for the wheely game.
Your fork is out of alignment. I take my 2000 fxdx up past 125 all the time.
I just got a 99 FXDX and the other day I hit 90 for the first time no wobble at all
Fork out of alignment? Lol its his steering neck, its loose. Needs to be tightened.
Forks out of alignment was the problem with my 07 Dyna SuperGlide.
2000 miles later and I've had no issues what so ever and I cruise at 80 mph all the time.
Harley says it's not a problem so press on and don't worry about that shake!
Great video. Got a Dyna lowrider wobbles around 90mph. Might do fork brace. Need to start somewhere other than laying it down. Thank for info
start with new neck bearings or at least have it adjusted.
I have the speed wobbles. Try true track first. I’ve changed almost everything on my Dyna but stabilizer. I say try true track first because I’ve tried everything else. I have Big Bear choppers front and rear motor mounts and wobble is still there and so much vibration that I can’t even ride the bike. All new front end suspension, bearings, racers, stupid fall away, tires, and rear suspension. I’m taking big bear front mount out and replacing with new original mount and true track. I’ve tried almost everything for this wobble and I’m hoping that true track finally fixes this nightmare
did it work?
Did you fix it?
Dude good video! I'm watching your video, listening to what you're saying and suddenly realized where you're riding at. Weird seeing an area I live in on the tube. Thanks for the video, gotta do some aftermarket work. HD makes a good product, aftermarket makes it a better product.
I've never had wobble I run good tires professionally installed. I check air pressure every week, front goes down slowly, I have to air it every 2 weeks. And it's done this for years. If guys have wobble you have something wrong. A university in England did an extensive study on wobble its on RUclips every rider should watch it. Education may save your life.
hey! My motorcycle Dyna 2010 FXDC has a lot of vibration, and I hear you say when you bought your motorcycle that your motorcycle also had a lot of vibration. I installed a new Front Motor Mount and a stabilizer. my tires are good. my suspension is good. what did you do to get rid of the vibrating? greetings from Belgium
Nice sound! Good points too! Thanks!
It doesnt happen to me going 100 mph i just muscle through i tear it up in the canyons too. I have gotten rear steer i never fight it just keep the throttle steady and GENTLY apply rear brake it fixes itself. Alloy art combi stabilizer kits help
Those are controllable. If you get the real wobbles, there is no stopping it, no throttling out. You just start praying. It's something else. It happened today.
From a guy who fixed his wobble: “These older models with the 39mm needs more stabilization. I have the GPR and a fork brace and it killed my wobble. Also, neck bearing, and front and rear motor mounts. Replace all that with brand new stock Harley ones and it goes away.”
people wheel stand these machines and this hammers the hardened bearings into the hard raceways. this pits and damages them adding to loseness and a wobble as well. this applies to any street bike
My wife and are watching this and watching you line split laughing our asses off
What’s funny about that?
It could be anything from tire pressure, loose spokes, miss-aligned engine/swingarm to frame, Fall away adjustment, worn out motor mounts or worn out swing arm bearing and bushing. Feel free to contact me if you have any questions.
Totally agree. In this case, tire pressure was at fault.
Please read my post Dyna Kac3
... but... thats Harley
Thank you for the info. I have a 2000 rd king that I'm having this problem at 90 95mph. I'll def check everything mentioned!
I would just get rid of POS designed bike like that. Thats my fix for it.
This. There is no justifying Harley's faulty engineering here.
Hit Kevin with Big Bear Performance up.
1st thing check head tube torque setting all that other stuff is your band-aid.
I got that wobble about 120mph on my 01 wide glide with the screaming eagle 88
Holy crap. Think I'll stick to my Triumph... it doesn't wobble.
I wouldn't worry about wobbling. The way you are riding you're not long for this world. One of those four or more wheeled vehicles will close the door on you eventually.
U should have a steering stabilizer on there but what’s probably causing that is ur rear wheel is out of alignment, need to be perfectly straight in the rear and u won’t get this, plus new front and rear tires would help too
Another thing you can do is buy a good high quality full face helmet that fits snug and drop the windshield.
I got a fork brace on my 14’ dyna wife glide and it made a big difference in the way it handles... might of made the steering input a little too sensitive... not sure on the effectiveness of alleviating wobble tho... I never rode hard before I put it on so I don’t have anything to compare it too
predator front mount a new fact rear and keeping under 80 your fine these were never made to ride over 55 60 mph the tech is 1980s including the biased heavy tires. incase your not aware they also bias the weight on the rear wheel so leaning forward and placing more on the front tire also helps. but the predator mount was worth every dime they charge.
Keep it under 80?… Ride a scooter with some handlebar tassels 😂
Great video. So the tires are 29 PSI front and rear now and there is no more wobble? Or did increasing tire pressure to 38 PSI rear and 32 PSI front sort it out? Thanks
Still no answer huh...
I had the same problem. The rubber engine mount are soft-losse because there are not new and that is the wobble. The problem is if you put stiffer mounts its gonna be better but you will get more vibrations. First ride on my bike and I didn't like that rubber feeling between my and road, plus the wobbles... The first month I was more reading on internet than driving the bike lol. If I know that before I will buy only softail. The feeling is like driving saab 9-3. What help fix this wobbles and also get rid of that rubber feeling is to put front and rear stabilisers. No wobbles and the feeling is 90% of full frame bike what is all bikes on the word except this hd lol... BTW the wheel alignment doesn't help because you have only 2 wheels then they cant have problem. Yes the body of the bike will not be straight-parallel with wheels but the two wheels will be always parallel between to other. You can not make two wheels unparalleled at all because then you actually turning. One more thing- I also did put fork brace and yes helps a lot. The bottom of the fork is bad bad. The axlebolt where is attached to the fork all that mount is weak. It is actually looks like joke that two screws on the right fork what is hold the axelbolt. Any another bike has clamp on that bottom.
There's a kit to put a heim joint on the front engine mount to keep the engine and trans in the same plane as the rear wheel. But he should have that wobble at that low of speed. Is his front engine mount loose or needing replacement? Did he check his wheels vertical alignment with magnetic angle finder and use the top engine mount heim joint to adjust?
Sir, I have a small Dyna only performance shop, and I am not going to sit here and guess the issue or all the issues with your bike, but that being said, you Sir have some very serious problems there. Shaking like that at only 70-75 is significant. Have it checked out by someone who knows, please. My daily driver has almost 80,000 miles, and I spend a fair amount of time at dragstrip with it. It doesn't shake.
bbc motor mounts are pretty good
Mine did that to me today around 100 mph. I just let off and held the bars steady. But there was some slight wind where I was at
My Fatboy does the same thing anytime I hit past 90mph I have 16 inch apes on mine but even before the apes I had the issue I’ve just gotten used to it and now being in a small town in the middle of nowhere it’s a non issue but it definitely sucked on the cross country trip I made
A list from greatest cause to lesser causes of wobble , loose or worn out neck bearings, loose or worn swing arm bearings, loose or worn wheel bearings , worn tires , incorrect pressure , out of balance wheels , worn suspension components, loose motor mounts, or rubber vibration isolators , weight distribution..At the Toronto bike show , between 1978 & 1980, BMW took their largest displacement bike, & (on a closed course in a straight line), put a single 15 to 20 pound weight on it, & shifted it from the back of the bike forward, & then in different locations that drivers would normally carry weight .This was to imitate adding a fairing or luggage etc .The bike developed a near tank slapping wobble at 86 mph ! Consider that it was a new bike on a closed course ,& that it cost twice the price of the same displacement japanese bike!.. Koodos to BMW for having the guts to show the truth ., & show the reality of possible causes..
My Dyna has over 50,000 miles and never a Wobble and I've been North of 120 plenty of times
Robbie's Incoherent thoughts enjoy jail
Just a smart sharp talk about safety while lane splitting at highway speeds... wow.
Hi Crash. Where are you located? I can eliminate that wobble. The Straight Shooter will locate the problem and we can make that bike handle like it's on rails. The video shows the engine/swing arm is out of alignment. There is more tension on one shock than the other, causing a handling issue. I eliminate harley wobbles all day every day!
where are u at im in Ohio
@@markmorris2336 I'm in Rancho Cordova, just outside Sacramento California. I wish I had a shop out there to send you to but it doesn't seem like shops out there are concerned about eliminating the wobble. The closes one to you is either Browns Cycle in Dallas Texas or Cycle Tech Industries in Hurricane, Utah. Or you can email me and maybe I can help you out.
@@RackandPull thanks for mentioning Brown's Cycles. They're 25 minutes from me and after doing new tires, wheel bearings, Sputhe Positrac Stabilizers,and front and rear suspension on my 2016 FXDLS this weekend I think professional alignment is the last step in making my dyna handle like a dream.
@@RackandPull hi Rack and Pull any shop recommendations near to San Jose California I have the same problem every time on 75mph to 80 mph (and not problem with someone up... past 80 mph )
@@brunorivas7985 Hi Bruno. There is a shop in San Bruno Grumpy's 650-873-8300 and they have the Straight Shooter.
Happens to me all the time when I lean over and my pipes or primary smash the cround going about 80 to 100 around a sharp corner lmao
I saw an old Mercedes W123! Woop!
Seems like a front tire out of balance problem. Then I'd suspect neck bearings. But yea tire pressure and balance. I was at the sand dunes with my tw200. To get through the sand I let pressure out of the rear. It was fine. Then I figured let air out of the front tire. I go going and immediately fell off the bike.
bad motor mounts?
Fork tube height and neck adjustment 😂 my 09 FXD has no wobble at all
check the tire pressure my friend !
DAMN I miss my dyna.
The wobble you showed in the beginning of the video was that before you installed the stabilizers?
Motorcycle tires bleed air. You should be checking pressure weekly. I run 40 rear and 38 front on my RK. I have been riding at speeds up to 108 and never had an issue.
RK and Dyna are very different bikes. You however are very correct on the tire pressure.
I had a wabble that started at 85-90 miles on my 04 dyna I changed my handle bar rubber grommets in of problem.
What do you mean u changed the bar?? Sorry am new at riding
Honestly, if the intent is to make videos, then the smoked windshield has got to go. It's both a visual obstruction and the focal point of your video. A clear screen might not represent as well aesthetically, but the choice is going to have to be one of process... HOW do I frame my shot, HOW do I maximize the visual appeal of my content? Versus how do I make my bike look sick.
You dig?
I've got a street Bob with 40k miles. Ridden like I hate it constantly. Front motor mount is most definitely shot and probably the rear as well. Cheap mismatched shinko tires, and static balanced wheels with fishing weights. And super tall T bars. It had a head shake problem at 15k and I replaced the neck bearings and torqued them to 90 ft pounds because of the Harley under torque problem. I can ride it at triple digit speeds with no crazy sh#t like that.
I just hit 40k not to long ago and i'm pretty sure I need neck bearings. Bars straight dead on it feels a little loose in the front. Move them just a hair left/right and it feels nice and tight.
Eric McGraw you most certainly did NOT torque the steering head bearings to 90lbs, the stem wouldn't turn then. You must be confusing the crown nut with the bearings. The bearing adjustment is a touch over hand tight.
New rider here bought a 2019 breakout should I be worried or did they iron out the issue on new model's
After spending that kind of money on a bike you shouldn't have to do anything to the damn thing for it to ride like its suppose to. Harley is still way behind on mechanical technology
Bike is ridden well beyond what Harley ever intended which is a big part of why this issue happened the first time. In this specific case though, the problem ended up being tire pressure.
Buy used!
they're not behind on technology, they're ahead on building crap to fail and having it come intot the dealership for repair. Victory hasn't once had to warranty a motor, last i heard. which is probably why they're not doing so great...
Wand Erer Ya but didn’t they like.....go out of business?
Fuck that. It’s not the ruts it’s the bike.
Dude , you're lanesplittin with one hand !!!
Ha someone else noticed. Looked like a healthy speed 2
Take the fairing off had the same issue on my fxd now can do 120+ no problem
condor 408 - agreed! I had a quarter fairing on my Dyna and made the wind factor worse! Took it off, now riding at fast speeds is a breeze without it 💯
@@saulpaul7263 Hmmm. interesting. I have a street 500 and I noticed the other day when I took it around 75-80 I got the wobble and I do still have my headlight fairing attached.
Frankies World the street 500 and 750 were never designed to go super fast on a highway there inner city bikes so I wouldn’t expect it to be able to handle 80+mph without some modifications.
Did you keep the preditor front mount with the true-track installed?
Why are you lane splitting at that speed.
I’ve ridden plenty of Dyna’s that rip smoothly over 100mph - That’s just something wrong with your bike. Improper maintenance. Could be a million things from worn neck bearings to improper wheel balance.
No more videos man? Not enough current dyna channels. Come back!!
I never knew splitting lanes at hiway speed was legal, is this guy a harley tech? He should take his bike to someone that can cure his problem.
Should’ve bought a road king I cruise 100 with one hand on the handle bar 👍🏻
My 09 nightster doesn't do that at all
What size and brand is that bar?
Shit tire pressure, the tire itself, speed and your weight. Now you know why they stopped making the Dyna, and the pre-2009 touring frames. You slowdown the wobble stops
Never had an issue on my fat bob
Its not a dyna thing. ANY bike with a problem can wobble. I felt a very slight jiggle on my fx, i replaced the front tire. No jiggle.
My sporty does the exact same thing
i would add shocks
Which tire? Is wobble common with wire rims? Is this on all Harleys?
No it's a Dyna thing doesn't matter what wheels
He should be checking the balance of his wheels also.
good video
I installed Progressive 444 shocks & Alloy Art Combi Stabilizer Kit on my '08 fxdb and I have 16" apes, the stock shocks suck. Similar issue on turns but I feel it comes from the forks, just don't think they stay perfectly parallel on bumps in turns. Only thing I can think of is get inverted forks if you can afford em. These bikes were never designed for turns I guess either way I twist the throttle and all worries go away.
444 aren't the greatest but should be much better than stock. It wasn't until after I did the rear shocks that I realized how bad the front end was. Terry cable has got dampening rods to help or race tech has got some stuff aswell. Hands down an inverted front end would be killer but there are other mods that can be done for much cheaper to get the bike to handle better.
In my 2016 I have the 12.5" 444s in the rear and up front the Progressive Monotube systems. It's WAY better than stock but I wish I knew about Legend Suspension and Racetech before I bought them. Inverted is better but you can build an awesome front end with parts from Racetech for a lot cheaper that will perform pretty close to the same on the street. RWD is entering the market with shocks too.
Big Bear performance
I have a 95 original mounts and I wheelie. When she wobbles maintenance the forks Problem solved. You're just baiting for sponsors
M🎉v rod doesn’t wobble at 150mph
I have this on my softail…
Bull shit. My 2009 fatbob Dyna has no wobble what so ever. Solid and I rip the thing with stage 4 over 120 mph..He has something wrong with his bike. Tire out of balance, fork or something.
MY dyna lowrider rips at 143 mph? 120 jims powered?
I stopped watching at "I dont know if there is a true fix for it"..... Suspension. Suspension. Suspension. Harley suspension is notoriously shit, any aftermarket high quality suspension, set right, is going to eliminate this and make the bike stable at 140+.
Bigger safety issue here is the danger of passing traffic on the right.
Harleys do not go "really fast" though...
What size bars are those ??
Front tyre. My Wide Glide only does that when the front is low on tread.
What year is your wide glide
@@392jenkz4 2014
Robb Phillips same tires are new but I bought it used wit 10k miles. Steering was adjusted. Recently did not work
ultimate fix- buy a FXR😂
Easy fix
Maintenance...can trust shops
My Dyna has 50,000mi and never wobbled so fix your bike
What i can't stand is his unsafe passing, guess he thinks he can die twice. Legal or not, it stupid to pass on the right or within 12"s of cars. Not observing safe following distance, cutting in on people without any space for them to brake......it's a recipe for death. At least he got to there a few minutes faster.
Dyna wasnt meant to go 80mph? huh? that's normal cruising speed on the slab
That is BS...saying bike wasnt ment to go 70-80 mph...I have no problem running that speed or more...so your reasoning is BS..
