As far as i know a bigger fly wheel will make power delivery smoother and less aggressive, not give it more bottom end. It will be harder to stall and rev up.
Hey, great video. I think a lot of riders think the 125 can't make a good woods bike, but you just showed a simple mod plus a few others and you can have a great woods bike - especially for new riders or those who just don't want mega horses. Nice job.
I have used Steahly's off and on for 25 or more years, always worked great for woods and dessert riding. Also company owners ride and there kids ride. Thank you for the Info 🏁🏁👍🙂🏁.
Glad you like it! More bottom is always good!
Absolutely!
Cheers mate! Helps to see other's experience. Going to do this to an RM250 and YZ400F!
Your collection of bike's is growing by the minute 😁🤣👍
Thanks for the great video. I'm considering this mod for my 125.
HeroRR, thanks for this vid. Hugely helpful, thanks!
Hey man great video and information your video is super clear is there a trick to this ..?
thx for the vid. going to put mine on now. 2012 250 sx. also putting the green powervalve spring 🤘🏻
Thanks for the video bud. I’m getting ready to install one on my 2015 200 (same bottom end as yours). I ride mostly woods and gnarly clay trails so I’m looking for more traction
DUal stage reeds and 6mm thick exhaust spacer gave me a lot more bottom end on my 89 YZ125.
Nice video, I have a flywheel in my 250sx, I would say it just changes the engine character, makes the bike chug along better at low rpm, makes the bottom end power more usable while sacrificing some of the 2-stroke explosion, you don't loose hp it just slows the hit, less likely to stall is a huge plus for trail riding, not sure how it will be on a 125 but for trail riding its been great on my 250!! Cant wait to see more VFR and dirt vids!!!!! Keep it up man!
UnleashedSoldier does it make 2 strokes easier to balance when wheeling ???
Ive just bought a 2014 200 exc as my first bike, I'm really struggling with the explosion of power, Im trying my best to learn to ride and it just keeps trying to race off all the time, especially when i get whiskey throttle! do you think a flywheel weight would help me?
Very nicely done. Thanks for the information.
Heavier to rotate doesn't "add" anything. Its harder to rotate initially, but once its going the momentum will carry itself better. It will make the driveability better at low speeds better chugging without stalling because of inertia of the rotational mass. I hated a lightweight flywheel on my Subaru. Yes it revved faster but I went back to stock for better driveability
Opened the casing on my bike and discovered it has one of these weights fitted, no wonder it was so sluggish and keeps dropping off the pipe in between shifts. I'd strongly suggest nobody fits it to a 125 unless you want your bike ruined. Even with 13 52 gearing it's awful. Also incredibly hard to remove if it's been on there for a considerable amount of time. Useful vid 👌
Vfr 800 is the winner for me ;)
The old flywheel add on haven seen that for years ... big for the old farmers.
Might pay to check your jetting.
I feel 12oz on a 125 is overkill but it gives us a chance to see on a more realistic scale how power is improved so nice vid bro
Isk if you still have this bike but it sounds like your needle is too rich.
I have KTM SX 150 2014, I added 10 ounce flywheel, and since than my spark plugs where going out about approximate 7 hours ( i was riding really slow and technical staff) jetting was from manual and I even put smaller idle jet, but still spark plug was in oil, thats the reason why spark plugs died. I took off flywheel and rode same trails that I rided with flywheel, spark plug is clean and like new, no oil on it. Do you have noticed something like this? I guess I better sacrifice bottom end for spark plugs.
Hi HeroRR. I am getting my 1991 YZ125 dialed in over the last year. I am having issues with lack of power on hilly single track, in particular on the bottom end. Did you notice additional torque to move the bike on hills? Thanks!
A another good way for just pudding around ( not giving it full throttle) you can change the gas and oil ratio ( a little less oil )
Or just jet the carb properly👍
Would have gone the 250 myself. Or the 300 EXC if going street legal.
Had the 300 and was a great bike. Rode a kwaka 125 motocross bike and just can't compare lol.
Hey new rider here , I'm a smaller guy and got a 2 stroke cr85 , the powerband is insane and I'm wheeling 1 - 3 , do you think this would help keep the bike on the ground a little easier? Nice bike BTW 👍
I don't know if it's too late but yeah it should.
Btw if u arleady bought it can u tell me how it feels cuz i have the same problem and i'm thinkin about getting one
@@tudorfecic4308 hey I did end up getting a 9oz flyweight , it did seem to take the bike a little bit , you still had all the power it would take a little while longer to get to the power hence less of a pop when powerband kicked in , ended up moving to a ktm 125sx anyway way more comfortable and easier to tame.
replace to a small front Sprocket
It is going to be perfect for low speed
Any science on how these things perform?
U need to swap for a 250/ 300, both are easy to ride.
Is that flywheel or clutch, sorta think that's clutch?
The Video is studdering a lot. Is that just for me? How many B-Frames do you use when you Export the videos?
Soooo you buying a Honda crf450l like you said you would in your “Honest conversation about the DRZ400SM” ?
450l isn't a sumo
Also I have a 450 EXC Sumo now, as seen in this video. No reason to buy something newer anymore.
Why didn’t you add the 2014 ktm sx125 to your bike list yet
On my website? It’s on there. I can add it to my description too.
HeroRR I checked awhile ago and didn’t see and was confused thanks for responding
Where did u find that engine stop tool who makes it
Steahley
I'm amazed that horsepower isn't negatively effected.
Torque is how hard something pushes. Horsepower is the rate of acceleration, how quickly an engine or electric motor, can spool-up. The Rev-limiter, is the top-speed of the engine itself. And the Red-line, is the suggested top-speed of the engine, because past that, you're more likely to break something.
So with any vehicle. The point of making any rotating part, be it a flywheel, crankshaft, wheel, selected tire, whatever, the point of making spinning parts lighter, is to improve the rate of acceleration & deceleration.
In other words, improving Horsepower and stopping distance.
Reducing the rotating or reciprocating mass of a part, is more effective, then removing the same amount of mass, that's sitting on the suspension. Like replacing body panels, fasteners, and any batteries, with lighter versions, won't be as dramatic of a change, as removing the same amount of weight from the unsprung suspension parts, the wheels, the pistons, things like that.
But I don't know if this should automatically apply to flywheels...
Flywheels, crankshaft dampers, and weights like you added. The point of them, is to store energy, between the power strokes of an engine.
So reducing the weight of the flywheel & damper, will improve the engine's ability to change speeds, but it maybe less smooth, may struggle climbing hills, and maybe easier to stall. A heavier flywheel/damper, should do the opposite of these things.
Have you seen the machines that crush big rocks into pebbles & dust? Their flywheels are MASSIVE. They take a long time to spin up. But once up to speed, they easily pulverize rocks, because heavier flywheels store rotational energy, and they resist change.
Long ago. When I was in automotive school, enthralled by Gran Turismo 4. I asked an instructor, what are the benefits of making a flywheel heavier, instead of lighter, because at the time, I didn't know.
I forgot what he said, but he basically said, don't mess with anything.
USELESS.
I guess he wasn't into hotrods & Tuning.
Understandable.
Mechanics hate modified vehicles, because they don't know if a problem exists, because of something OEM, or because of some mod they don't know about.
More reason to professionally repair & maintain your own vehicle, if you want to modify it.
That's what got me into Tuner-car culture, racing, cars, and now motorcycles exclusively in real life. I adore modifying, because I not only personalize a vehicle's appearance, but also make it physically fit my needs.
Which is exactly what you did, adding that weight, to your bike.
So things like flywheels, certain weapons/tools, and to a point, sexual partners, are the only things I know, not automatically better, from being lighter.
You are like an engineer or something
@@64maxpower
Yes. And I am still learning.
Orr a beta 300rr
It's like a trials bike now
@74 CYCLES (sarcasm)
Add blue Loctite too
*N U T*
Never check it
Please buy a 250 or 300xc or xcw
300xc is sick. I’ve had a couple 250/300xc. Will be adding another one soon to go with my 150sx I’m building into a trail bike .
The exc has more bottom end than sx. You should have bought that for trail riding.
Too late now. Lol
The motocross bikes are much cheaper to start out on, than the off road bikes are. That flywheel weight is a really great start to taming a motocross bike. There are a few other things he can do to help as well. Different pipe combos, gearing, head work, reed block etc. Also, the suspension is probably pretty still on that bike. Its all in good fun though. I converted my cr250 to a off road woods bike and it does great!
Cheaper to buy an mx bike and add a flywheel weight and a pipe than to buy an offroad bike and buy moto suspension. For those who ride both its usually easier to accept the compromise on the trails
If you had to check it every 10 hours i would have one fucked crank case
Ok these do not give you more power it takes the hit away they normally put these on beginer bikes and yes trail bikes aswell this will make you less likely to stall make your bottom end power more usable for riders who are timid and dint like reving the guts out of the motor infact this will actually slow your bike down ITS A 125CC LEARN TO RIDE IT AS IT IS YOU WILL BE BETTER OFF YOU SHOULD OF SPENT THAT MONEY ON FUEL TO BECOME A BETTER RIDER
when did I say that this would give me more power? The one thing I hate about the dirt bike community is everyone is all about how you have to be an expert and constantly be improving your skills and any mod that makes life easier is just seen as cheating and not being proper. Bottom line is I installed and used this part and I really enjoy it, if you don't then that's great don't buy it then.
@@HeroRR did you or did you not say it will give you more bottom end yes you did thats your exact words you dick to get more bottom end you would need a increase in hp this changes the characteristics of the power you already have you say 3 or 4 times LITLE BIT MORE BOTTOM END WHICH MEANS MORE HP YOU FUCKING DUMB ASS
mx documentary tv mx documentary tv Jonny walker had a fly wheel on his 300 I wouldn’t say beginning back they are definitely meant for 2 strokes strictly enduro
Being a better rider also means understanding bike setup, which in some cases means a heavier flywheel, softer suspension, or a different gearing. Motocross track? Light flywheel stiff suspension, maybe richer jetting for revving explosive corner exits. Woods riding with lots of slippery climbs? Heavier flywheel, softer suspension to keep traction, leaner jetting because you're not doing explosive corner exits or trying to make long doubles on slippery rocks or gravel climbs.
@@mxdocumentarytvmxdocumenta2221 by more bottom end he didn’t mean more peak horsepower 😂 he meant more bottom end and he was right
