Top speed of supermotos?

What kind of top end would you expect from a 500-650cc supermoto if you tinker with the sprockets?
I DO realise that this kinda bike isn't built for speed but i'm just interested to see how fast people get them...........and also to work out if my speedo is buggered or not!

Mate, your lucky if 50 % of peeps on here have speedos.......

I've no idea what you mean, officer

Supermotos have speedos?

Yeah i realise that too. So those or you who have speedos......I'm riding a Husky SM610R. The speedo is driven by the front wheel and the bike is designed to run the 17" wheels that i'm using. Its a Husky speedo that was fitted to the bike when i bought it but i've no idea if its the one the bike was suppied with when it was new or even if the bike came with a speedo when new.So the speedo has 200kmph on the clock (about 127mph????) and it runs off the clock. I'd be amazed if it was this fast. I'm used to riding big sports bikes and ok the Husky does feel quick but i put that down to lack of aerodynamics and upright riding position.Most speedos are inaccurate anyway. My TL1000R read 175mph flat out and GSXR750 180mph so it could just be that i suppose.Could the speedo be from a different husky with Enduro wheels maybe?

I managed to get 111mph out of my KTM 625, that was with an Akrapovic end can on and standard sprockets.

I got 165mph out of my YZ400F two weeks ago, but the trailtech speedo still needs calibrating. Dunno; on a race track Iddon was clocked at 127ish I think???

hi there i have a husky 610 and have seen over 120 on speedo with different gearing usually geared for about 100 though much more fun :burnout: hth chris

It might well be right then huh? Shes fitted with an Akrapovic titainium system along with airbox mods so it could be right enough.Its the first bike i've owned where i need to think about where i'm going and then change the sprockets to suit. Like Chris said its much more fun with the husky topping out at 90/100mph but then a 30mile run on the open road is a total nip! The way its set up just now i can cruise at about 80/90mph without sreaming the tits of it but 5th and 6th gear aint very responsive I guess i need a road bike now too!

Sounds like you need a Highland mate Mine will cruise easy at a ton+ with it just tickling the max torque rpm range It's just had its first service and ecu reprogrammed and apparantly it's even quicker. I shall pick it up tomorrow and see

Dunno, mebbe 120?I seem to remember reading in John Robinsons about his hillclimb CR500 where he said the theoretical top speed of it should be about 127 mph.Fucked if I would want to ride my KX at that speed cos it gets a tad twichy at about 90.

Yeah but the title says Top speed of supermotos?

I know nothing about Highland bikes at all. Infact i don't know if i've even seen one before.Think i'm gonna buy a Superduke when i get back from Zimbabwe. I'm taking a test drive of both the Superduke and the SM950 in 3weeks time.I'm almost wishing my holidays away!!!!

My XR650 with 17" wheels (with present gearing 15/46) will do about 95-100mph absolutely flat out.My trailtech (which is calibrated) says my max speed so far is 96mph.The engine feels happy if I keep it sub 90mph and spend most time up to about 80-85mph. It still accelerates quickly though. Could go to 15/42 and get about 105-110mph but I want to keep the quick acceleration I have. I tried 15/45 but I prefer 15/46 gearing and lots of go through the gears.All high speeds attained on an old piece of private land.Tim

Supermoto enough to race in the NORA series

I get about 105mph out of an 04 640 LC4 with an Akrapovic system on 17:42 and the same with 16:42 gearing.

Very rare piece of equipment mate. They are what the KTM 950SM aspires to be, but won't for a couple of years 950 cc fuel injected vee-twin SuperMoto

Lets face it guys theres a few things were missing here,just how many times do you go flat out?,and i know kitefighter must be using that hill down off the dava moor to get 127mph out of a husky .But this is the real prob unless you have you speed clocked on a pukka timing lights etc then its all boll$£ks as its just indicated speed which is worth nothing ,but does make you feel good

You've totally missed the point mate! This isn't a 'my bikes faster than your bike' post!!! I'm just interested to know how fast peoples motos go flat out. I know that not what these bikes are about and i know its not something folk do often. I just wanted to know if my speedo worked correctly.Should have just used the GPS in the first place.

Aye but the bar is set pretty low, wasn't there a bloke racing a Triumph in it a while ago

No matei know was just pointing out that unless you use a gps etc its not worth doing

Now I,ve got my trailtec working properly my XR600 does 106 with quite alot of engine and airbox mods, Although thats not using GPS or the bruntingthorpe timing lights!!!!

That highland in the Nora series flies down the straights, seems its got way more power than anything else. I bet with the right gearing 130mph could easily be achieved.

Loads of times today. I love Scottish roads

you probably need to fit a speedo drive geared for a 17" wheel on it, mine used to regularly hit 115-120, until i fitted the right drive ,now maxes out at 100ish, but can't really see cos head feels like it's in a wind tunnel.get it at talydodabs

Ahem ................................

Is the highland not a 950 v twin? if it is theres no comp .How can us lot on 600-650cc get 130mph any way if it is! its slow for a ltr v twin

It is a vee-twin, but as was proved at Blyton it has been geared for acceleration.Not saying it is brilliant, but I was giving rides out at Blyton and there were no returns without a grin

How did i know you would bite ,im just jelouse

they changed the brands round last year in the winter series and had that cut back in clearways to stop people getting too much speed down the start/finish straight because iddon and a couple of others were clocked at 127+, steve

H & M tuned Husky SMR600R Dyno at 65bhp@8000rpm = 128mph

MZ Baghira, bog standard, 2500kms old. M11 southbound, junction 6 to 5. Early morning, tempreture cool and with slight mist. GPS fitted to works car driving alongside. 118 mph.

TDR 250 showing 110mph on clocks

My WR does about a ton flat out, with a 50T rear sprocket.

Yeah that actually sounds reasonable. Mine did >100 with knackered powervalves although it took a while to get there.

Stuff and nonsense. This is a very interesting question so I thought I would take a scientific approach. Using my trusty SM570R with typical can and airbox mods as a reference. I spent some time calibrating the TrailTech speedo.Firstly I paced out 100 revolutions of the front wheel and measured the total distance, divided all up to caculate wheel diameter to the nearest 1mm. I then used Michelins excellent reference on tyre growth vs. speed to introduce a correction factor to the rolling diameter. This figure was entered into the TrailTech computer.I found a 1.5 mile long straight for high speed tests and set the bike up with a selection of different gearing to allow the bike to just rev out in top gear. We used a video camera (at both ends using Time of Day timecode) to record runs in both directions and averaged the results over six runs in each direction.Finally I am happy to declare possibly the most accurate and scientific measurement, corresponding to the Guinness approved method for motor vehicle speed recording. On a cold, dry day in March we ended up with an impressive 217.236 miles per hour. Good old Husky and thanks TrailTech!I hope this puts everyones mind at rest and we can remain happy in the certain knowledge we have some of the quickest machinery out there.Meeow.

ah bollox to that, everybody knows that my berg breaks the sound barrier in 1st gear huskies, i've shit 'em

Just got it back from service and ECU re-program ........................... fook moi, it was quick before. Now it is substantially quicker

Well the XT will indicate 100mph if you hang on for grim death, but as the speedo still thinks I've got a 21" front wheel its probably more like a wheezy wobbly 85. But then, even when it still had a calibrated speedo, the most I ever saw was about 89mph... the difference is that back then it had to fight for every last mph, whereas now it just zips straight up there.

Used the GPS yesterday whist out for a short run. Highest recorded speed was 122mph with my forehead on the bars. Quite suprized it was that fast!
