For all you Australians (and everyone else that uses kmph) watching this. Top speed is *138 kmph*
Your welcome
Sounds like a plan thank you
@@otisliplays.8393 all good mate.
Cheers mate
@memlord well sure, but was talking to the Australians. 😜😂
EURO BROOOS
Needs regeared . Has the power for 120mph at least.
86 is fast enough for this old guy. stock gearing, speed it right on for factory specs
It doesn't need anything. Gearing is completely subjective. I'm sure the rider prefers shorter gearing.
Having two sets of sprockets and chains is nice if you ride both open fast trails and tight woods. Even if you don't top out the taller set. Crusing dirt roads sucks spinning a ton of rpm and riding in the woods with stock or taller gearing smokes clutches.
@Jnl Jnl
Correct but this was surely to show the actual speed with stock gearings. And this bike is not made to be ridden in so high speeds in daily use so no need for too long gearings.
I think 100 mph si enough , but 85 it's still there
Thank you for that, I've always thought it would run about 90mph. I had an 89 KX500, and it was a beast. Posted and jetted. Always ran Cam2 gas.
Change the gearing to 15/38t, I put this gearing on my KX 500 Supermoto did 145 mph on flat ground pinned.
Thats a little too fast for me. Just wanted to see if mine still ran stock speed.
Fuck that's fast for a dirt bike haha
Yes you would never get up to that top speed on a mx track. I never get close even when i am riding in the bush and on logging roads.
These bikes have so much hp for the weight. you change the sprockets and you can get up to speeds that you really should not be going on this style of bike.:)
any chance of getting top speed (the correct way... the way you did it) on ktm 500
Finally not a video what takes 10minutrs
Maybe it's the old fart in me but I kept imagining a deer running out in front of you.
Lol i hear ya. i always make a pass back and forth. 500 scares pretty much everything away. Going to be finding something more open for future top speeds tests.
Tony Harrell I was thinking the same thing,game over at that speed!Its not the old fart in you,even when I ride on a small bike trail I'm always thinking something is going to jump out in front of me most likely a deer.
I've almost hit a deer, but newly fallin trees almost killed me one time.
Tony Harrell right on
While riding my mountainbike, i hit a wild boar over here in the Netherlands. Off course, there is no sound coming from a bycicle but i really made a frontflip, bike and all. I dont know which of us was more startled, him or me.
Great scott! Two more miles per hour and you’ll be traveling through time like the deloran lol
Lol
My CHP friend clocked us with his radar detector on a fire road in California City. My 2000 CR250 did 87mph (I had one tooth bigger on the countershaft sprocket). My Husaberg FE550E is a six speed with a speedometer and a Scotts Steering Stablizer, it's kinda of scary to look down to see how fast you are going on the small readout (KTM's have the same), but I clocked the Berg at 93mph - it had more if I wanted to press the issue. That's more than enough speed for me on dirt. A friend of mine had an 86' CR500 geared to the moon, he said his bike went in the low 100's. That's pretty insane.
Totally agree with the re-gearing comment. My old 89 TRX250r would hit nearly 100. Engine was built by CT racing and gearing was different but still that 500 will def push 120. Need to get me one 😍
Damn not bad, just sharing my own personal experience about my built my TRX450R it does 87 MPH with a larger front sprocket and of course the engine is completely built 480 big bore bone stock I was able to top it out at 77 MPH that was it. But in all reality We all know top speed is not what we want. Get up and go low end power is all I care for. Great video New subscriber here.
I had one of these in the early '90's. I knew it was fast as hell but never clocked it. Thanks for the video!
Mine needs a rebuild. It is still powerful, but it does not hit off the bottom like it should. Compression is lower than it should be. But it's still fun to ride as is. Thanks for watching.
@@TNTMOTO that's what I was thinking. I was like isn't this thing supposed to pull wheelies in 5th!!!
Thanks for getting right to it without a bunch of stock music and teaser clips. Great video.
Back in the late 80's had a 87 KX500 ported, and milled head for all top end big carb just pulled super hard on top guy did the work he built some score racing bikes geared it for top end. Put street tires on it took it to the drag strip did 11.90 @ 121mph when I would get out of the throttle went into a speed wobble made a few adjustments to the suspension still did it 2nd pass was the last time almost threw me from the wobble. I have taken to some dry lake beds had it even faster never had the speed wobble on dirt just pavement. Being in SOCAL/AZ lots of open BLM land to ride on with dry lakes beds, sand dunes we made many trips to Glamis back in 80's and early 90's was lot of fun. Busted up my knee doing some big jumps decided to give up the dirt bikes I still miss those days.
Sounds like a blast. I broke my back when i was 16, in pain every day. 27 years later i got the bug again and now i cant stop.
Tuck in and gain 5mph more.
You won’t gain that much
Christ it doesn't take long to get there 😮 I would love to have a go on a 500 2 stroke someday, in the UK they're stupid expensive especially when you consider the age of them
Saw the out of tune yz490 speed run and it seemed to jump between 60-80mph a lot faster than the kx in this video. Remarkably much faster. Great vids.
Could have been the gps lag but yes the yz490 was quick. Complete rebuild on the 490 next year.
my dads friend was a honda fanatic, he has all kinds of old elsinores and you name it, he was also a huge fan of the 500s because of the power but he said he actually prefured kxs over the cr. he said Kawasaki just knew what they were doing when they built those.
The seat/gas tank integration on these old bikes alway amazes me.
Yes the older bikes were designed to sit on instead stand on. It was a way different riding style. Today you stand most of the time on big wide pegs. People comment all the time about the amount i sit on the bike when i am riding not knowing that was the way the are ergonomically designed. New bikes are not comfortable to sit on. Hard seats and high handle bars meant to stand.
The bike to in my pic (klx300) stock besides gearing did 86
You should do a top speed run leaning down for better aerodynamics and see how fast that 2stroke can go
I dont think it would change much on this logging road. Probably different on a paved road
That KX is awesome. I'm a street bike guy but i'd love to own one. I'd probably get in trouble with the police if i had one.
Honestly 86 is more than enough but the acceleration is what I love about those 2 strokes
Flat knacker on a 500 two banger bloody love these vids.
I was just trying to figure out why is my 2018 Suzuki DRZ400sm faster than this KX500🤔 something must be wrong with that KX 🤷🏼♂️
Your DRZ400 will have a faster top speed due to transmission gearing and sprocket sizes. But when the KX500 hits 86Mph you will be a long ways back. KX is a motocross bike its geared for extreme acceleration.
KX500 bad boy for real
What sprockets are on each bike wouldnt be a fair test with out the same ratios for top speed tyre pressure clean air filters and running right at the altitude and humidity???
everything was equal with respect to both bikes running stock equipment
Good effort mate 👍 they have around 65hp, so some of those comments are correct. A change of gearing & 120mph is plausible
This was just a stock speed test to see if after all these years it could still go the original speed geared from the factory
Nice vid I had an 85cr5 it was a beast cracking the throttle was like a keg of dynamite going off , sold it and bought a 90kx5 great bike as well wicked fast too in the process of freshening it up now so while it's down I needed another half litre to keep my big bike skills sharp so I picked up an 88 cr5 just thought I'd share that and again nice video
Yes perfect description of the 85. "like a keg of dynamite going off" .I have never ridden an 88 cr500, but i have heard that they smoothed out the power to make it more rideable. Much like the KX500.
I managed to reach 118kph on my CRF450R on a fire trail once
You need to rebuild it is not reaching max speed and it is not wheeling like a kx500 would
back wheel is spinning on loose gravel every gear. and 86 mph is the top speed for a KX500 of this year with stock gearing.
How can you pin it on all gears without it trying to flip? I had a banshe e a little built and I couldn't pin it in any gear before 4th
Loose gravel road. rear wheel is spinning.
Team Green's Baja KX500s would do 120mph with the stock transmission, clean-up porting and a pipe. You need different sprockets for a max velocity test.
This was a stock gearing test.
I've seen desert racers gear THE KX 16/42 it topped out at 116 MPH.
16/42 over stock gearing of 14/47 is equal to an increase of +/- 7.65 MPH in this bike as demo'd at top speed if gearing was changed to example, believe he could have reached 92 MPH no issue. Just doing the math, but would really come down to individual engine performance which has a lot of variance depending upon engine mods... race gas, total weight (rider + bike + unsprung weight drag factor)... etc. Without a doubt believe a highly modified factory desert racer could reach the mark of 116+.
Had a 93 DT 125 R... enduro decaf 30hp bike and it had the same top speed.
You got plenty of power, go ahead and change the relation ;)
Done about 200 plus hours on the KX500 . Yep. They get along OK .
That bike should be pulling wheelies in every gear
It sounds like it needs a rebuild also
Rear wheel is spinning on the gravel road in every gear but yes it could use a new top end and carb rebuild.
Life of Rye Every 500 2-Stroke Dirt Bike that I have Rode Pulled Wheelies in Every Gear Too. That Bike Needs a New Piston and Rings.
Mark Fuller you can't wheelie when your back wheel can't get traction. But yes as I said in my above comment. It needs a top end job and carb work.
no doubt
The power valves take speed from the top end and make more power on the bottom end. We clocked a kx250 at 85mph. My Husqvarna 86/400wrx destroyed the kx250.
The pipe i have on it is a gnarly which is also for low end grunt
was it the stock sprocket sizes?....the moto-x bikes tent to be geared low...i always ran a smaller rear sprocket....more top end
yes this was a stock sprocket size
For posts below top speed was not trying to set a record just showing with the best stock 86 is top speed. Yes other bikes and hearing get it higher but if done who gets to 86 faster than 500cc 2 stroke?
I had kx100,yours 4x power, that's a nice bike!!
Them wher the days, on the back wheel on a big 2 stroke
another tip when balls out tap the kill button every now and then itll save your motor from a cease I've ridden so many miles in the open desert, full throttle its an old danny hamel king of the desert trick
i run rich and 32:1. i clutch and blip regularly. have never ceased a motor
The kx500 is fast that's for sure I think 96mph with stock gearing. My kx500 is the fastest bike I own besides maybe my 500af
perhaps mine is not stock gearing then, i have not checked yet.
I also think 86 is slow for a 500. My friends ran 105mph tapped right out nothing left to give next to a zx9. But we were on the highway not gravel. Bike was bone stock and brand new just broke in.
Spec for stock gearing on a 89 KX500 is 86 MPH, so i am guessing your friends sprockets were changed.
It has the horse power for much higher top speed, the limiting factor here is the gearing. My Yamaha WR450 had top speed of 170km/h (more then 100 miles /h) with stock gearing but that has a 5 speed gearbox made for it to actually reach top speed. MX bikes are geared for riding on tracks where you never reach anything near those kind of speeds...
This was a stock run.
Did they put a governor on the new bikes, my friends old YZ450F hit over 100 and could beat a KZ900 off the line
its all about transmission gearing,4/5/6 speed transmission, sprockets and horsepower. Most dirt bikes ranging from 80cc to 500cc are set up from the factory between 65-85mph. Then most people start by changing sprockets, then they change exhaust/jetting for more hp. Then its usually cc increase or head mods to get even more hp. Some of these newer 4 strokes with high compression ratios are getting 80hp after mods, which translates to alot of available power for sprocket adjustments. Biggest problem with 2 strokes is the power curve. Rear wheel just wants to spin rather than hook up.
It’s not good to use downshifting as braking on 2 strokes because they won’t get enough oil when you do
Plenty of throttle blips. 32:1. Fat jetting. Have never sized or damaged a cylinder.
That doesn't surprise me. My 450 pulls mid to low 80's and my drag toy eats 500 2 strokes all day lol. Bad ass video I liked
Yes those 450's are definite torque monsters. and hook up extremely well.
Which is faster in a drag race the kx500 or the cr500? Thanks
Stock, depends on what year. Top speed I think all the kx were faster top speed. If you can keep the CR from spinning it is like a sling shot on the bottom end. Probably not the answer you were looking for.
TNT MOTO cool thanks man! 👍
is that a dry break tank? was that some race model?
Desert tank. Not sure the brand. I have sold the bike.
Do they have the same sprockets???
Can the bike reach 130mph if we use 15 / 36t gears?
I don't know what exact gearing you would need but yes it has the power to do it.
@@TNTMOTO I really want the kx 500, but in Indonesia unfortunately it is not in the production of that motorbike
It's the gearing. My 1980 xr500 tops out at 97... Unless I change my gearing.. I can go faster or have more torque. So can't really compare this to the cr500 unless gearing was matched.
This was a stock gearing test as the description states.. The CR500 was also stock gearing for the year.
What brand was that speedometer it’s nice digital would like to buy same one
It is my phone using an app called Digihud
That pilot is lean or you're aircrew is out so far it's about to fall out!
Set the aircrew around 1&1/2 & give it a 62-65 pilot.
...or maybe you have an air or exhaust leak?
Stock pilot #60, air screw 1 & 1/2. 170 main. Carb slide was worn out and needed to be replaced.
@@TNTMOTO
Oh gotcha. 👍 Something seemed off on the low throttle openings.
Thank you for the reply. 🙂
There's so many factors ..so gotta say it's just a general speed ..all depends on set up ..right..one can make ..pretty much anything fast ..depends what you want to do with the thing..in my world ..
Just a stock set up speed test
I always wondered how fast a kx500 was thanks for sharing
Stock sprocket test, capable of much higher speeds with sprocket change.
Lucky man to own cr and kx500s
raymundo marte Luck is when preparation meets opportunity. If you prepare for it, the opportunity will present itself. Never forget that!
Why are you braking with your engine in smoker? It's not healthy for your engine :/
ImEddyslaw if you listen. I blip the throttle each downshift which gives the bearings enough lube.
Yea maybe bearings but not enough for piston
I run 32:1 not 40 or 50 like others. lots of oil for piston.
Does that ruin plugs running too much oil?
Rick Jones not usually, the plugs will tend to burn it off if you have the right air fuel ratio
That’s so cool! How did you get the speedometer on your phone? Is it an app?
Yes its called "Digihud"
TNT MOTO awesome! Great videos love your bikes!
Just as I expected it is a bit faster top speed than the CR. I ran my CR to near (or possibly at) top speed on my road several times in the past couple weeks. My tires are kind of dry rotted and the right side axle adjuster backed out and gave up the jam nut so I'm not sure how often I'll be doing this. I want to get around to having someone record a flyby though. Plus I damaged my silencer trying to repack so I'm somewhat out of commission until I deal with it. I also want to find a way to test my 0-60 mph time and possibly my 1/4 mile in addition to top speed. How are you able to keep the front tire down? I lean forward on the tank as much as I can but my front tire wants to lift regardless. As much fun as this is it prevents me from achieving maximum acceleration I'm sure.
gravel road. tires just spins the gravel on the surface of the packed dirt. 0-60 going to be tough to keep the wheel down anywhere but loose gravel. top speed use rolling start 20 plus before you hit the throttle. Now my bikes jetting is probably off because it had a fmf fatty on it and i swapped over to a oem. With my fatty on it, it was nuts.
TNT Moto Yea my runs are on pavement so the tire comes up hard. Usually I don't run wide open until 3rd, but still it lifts hard.
What gearing are you running?
TNT Moto I believe the stock 14/51. I'll have to check.
GyroPyro12 Your a daredevil, tie a cinder block to the number plate to keep your front end down or just deal with it its called power.
holy sh*t that thing can move, how many factory hp? is the engine still factory spec? whats the intro music to this vid?
factory spec bike with a fmf gnarly pipe, i would guess 60 hp

My KMX 125 used to do 85mph 2 up back in the 90s 👍
@W P I had a black and red KMX in 1991 and a Green one with KMX written in pink in 1995 the black and red one got stolen in 1992
@W P Definitely mate I wouldn't lie about it 👍
@W P I remember that colour KMX they were stunning mate!!!
Great power taking of looks very easy to throw around good video bro
Obviously it can pull more gear but you can also remove the front fender and lower it down in the forks and get a few more mph.
True. this was basically a test as is and what i believe to be stock sprocket sizes
TNT Moto what a ridiculous video. Have you ever raced dirt bikes? Gehring is everything. Depends on the track, conditions, Etc. Are you a newbie to dirt bikes or what?
What is your comments point? This was a top speed test of my kx500 with stock sprockets on it to see if it indeed did go the preset factory speed. This video has nothing to do with setting up the bike for different tracks. Of course the sprockets have to be changed for different races. racing styles ability etc. What is your problem. Oh by the way, thanks for watching and feel free to comment on further videos.
The CR is geared lower 14/51.The KX is geared14/47. These are stock gears.
The cr has a short ratio transmission from 89 to 91 maybe the 88 as well. My 94 has the wide ratio transmission and does 91 with stock sprockets
What app you used?
Digihud
Carb not clean? Seems like it’s held back
It could have used a new carb but this is a gravel rd. the rear wheel is spinning in every gear.
Love 500's I owe one now and have had a few but the gear ratio in the transmission is def higher in the kx's.
Yes probably why they became the preferred desert bike.
I don't think the Speedo was keeping up.even idiling away it was not responding and I would think it should be good for 95 mph
This is right in the ball park of stock speed for this year. Sprocket change and it would far exceed 86.
Has it got the same reeds exsught gearing sprocket size buddy lol
All stock except pro circuit pipe.
The top speed of the kx500 isn't that great really,but it's how quickly it gets there that is the buzz and considering it's designed for jumps and bumps,they do alrite!!!
Show me any single cylinder bike faster and no way quicker to that speed.
That powerrrr! 😩😍
damn thats bad ass... love 2 stroke with powerband
500 doesnt have a power band
Lower suspension add some clip on and street tires this bike will eat most any street bike in the canyons. Light fast and flickable. That is what a real sportbike should be. I would kill for that bike. Ninja and hayabusa would not catch it until 100 mph, and really how often do bikes have room for 100mph plus speeds on the street? Imagine stop light to stop light runs smoking all those 10 grand plus sport bikes and being able to run circles around them in the tight corners.
Only 86, that’s kinda weird when I go full speed on my rmx450 I can go into the 90s
Stock gearing.
Why a kx450 way faster I had stock everything mine reached 94 mph
Because your sprockets are a different size. The KX500 would get to top speed faster than the 450. Then the 450 would pass it.
Good video keep up the good work
Man if this were to have a Supermoto Setup
it has enough power to push it to around 120mph
My 85' Kawasaki KXT250 Tecate only does top speed with 14T front, tiny 34T rear sprocket, 73mph. And that's all I'll ever get out of it. Still, for a 249cc, 263# 3-Wheeler, it's acceptable.
That's some tight gearing. That bike could do way more I'm sure. An old klr 650 will do 95mph on gravel
Yes this is stock.
Your cr is geared much lower. My 94 cr has the wide ratio transmission and it tops out at GPS 91mph
Stock gearing
I got my fat buddy's Honda SL 100 to 63-64 mph in 1974. After he sprayed Either in the tank.
Phone can't keep up work the kx😂
What app did you use?
"Digihud" has trouble keeping up with acceleration but i think top speed is pretty accurate
Thank you so much!
i dont think the gearing on that is good or if its a healthy bike but ive seen a lot of kx500 and cr500 go 110mph easy
Stock gearing
@@TNTMOTO with stock gearing ive seen them go over 90mph
My old kx490 was close to 100 mph just race against cars and few bikes with speedometer on them got us at 98mph. Not bad. Sprocket change and Reed's will get it to 100.mph easy
This kilometrs or milies
MPH
Idk how accurate this is I once i did 102 on a 93 cr250r Hotrod crank and piston
Smaller rear sprocket is my guess. almost all mx bikes are geared stock 75-85 mph
My yz250 lightly nodded will run all of 105 so I don't get it
MPH? seems a little fast. must have a very small rear sprocket.
Is it street legal
No
I would love to live somewhere like this
Yes BC is a great place to live.
@@TNTMOTO I mean a place like that where I could just come home after work and rip a dirt bike around legally without a care in the world
@@I_am_BiG_Al when I lived in the interior of BC. I used to ride my bike to and from work trails and logging roads. It was the life.
@@TNTMOTO in London I grew up being chased by police everytime we tried to ride
@@I_am_BiG_Al :)
Big cr500 fan
my r1 got up to 100mph in 1st gear quicker than that got to top speed through all gears
200 hp, 998 cc, inline, 4-cylinder on pavement vs 63 hp, 499c -cylinder on loose gravel spinning rear tire. Not really a good comparison, but yes this bike could use a top end rebuild.
What a genius comparison
Try that again on dirt with your r1 you absolute meathead
its all in the gearing my kx with a 43 tooth rear sprocket and 16 front 103 top end
top speed yes it is all in the gearing.
My husqvarna te 125 has bigger top speed than that with 13-44 sprockets, pretty weird if you ask me but of course the kx accelerates like a lightning
Impressive speed, the same as a BMW S1000RR
in first gear. 😊
Probably have a tough time getting that bmw around the mx track at that speed though.
@@TNTMOTO , Agreed. A case of 'horses for courses' in more ways than one.
the 500s were sick !!!!!!!!!
I like that Gas fill cap on that Kx500, lol
Desert tank. Fast fill, you just push down. When i restore the bike, i will have two plastic sets. one original and one with this big tank
I just got one (kx500) off craigslist for 6000 i have never seen one for sale had to cop with in first 30 minutes of posting guy said their was 3 people on their way
Darn wish i could sell mine for that and that fast. im only asking $3500 cnd. I love it and it is a great bike but i have too many bikes and i want all the 89 CR's
Post a video, would love to see it
TNT MOTO if i had a action camera i wuold i have all sorts of quads bikes side by side
The 500 kx I had done about 120 mp and even taking off slow at top speed the front always came up never on ground unless you hitting brakes lol
A lot of people talk of these 120 mph wheel up in the air every gear KX500's but i have yet to see a video of one. I am not hating on the fact that people may have had one but i cant find a video with a speedo that shows it. Do you have a link to any?
