Popping Wheelies on a 250cc??

[Sensei]

Andy1 : Posted what I read .You don't say that you bumped wheelied your bike CBR250 into a wheelie. I read it that you pulled it up as with a trial bike from stand still or rolling so based my opinion on that & stand by it!! . I'll go ride with anyone here that think's he or she is fast even if they are . I'll learn from your riding if you are as fast as you or other's say you are . If not then you'll learn from me . Na just an old rider with 33 year's of bike riding having some fun while been safe ! Don't take yourself to serious guy's it may slow you down Sensei

There seems to be some confusion here.

People have different ideas of what a wheelie is so let's explain the difference. What Andy1 and Motoracer are describing (and I didn't realise in my earlier post) is travelling at a very high speed and the front wheel gaining altitude off the top of a crest in the road. The front wheel is off the ground so *technically* it is a wheelie.

What the disbelievers (myself included) were in debate over is the front wheel being lifted through engine power and held at a reasonable height for a decent length of time.

You mean the difference between power standing and a true wheelie...There are plenty of bikes that can pop the wheel up in the air (even for a little while) - I think the trick is finding the balance point, where the wheel stays airborne indefinately, with only minor corrections required.

How do you pull 195kph on a bike that cuts out at 180Kph? im not very smart but i can smell poo gas from here.

Quite possible the speedo was reading 195kmh, but there could have been a 10-15kmh error, between that and actual road speed, as has been mentioned on another thread. So it may have been just under the cut out ???

Are we sure Andy1's last name isn't Stroud ?

It's actually bloody easy to derestrict imported Hondas so it's very possible.

CBR250RR's have my respect . I've riden with one that could do 200KPH (he had to to stay with the VFR750 I was riding)

Just load up the front forks, open the throttle up hard and pull up. its easy when you know how If you use the clutch you dont have to pull it all the way in, just till it starts to slip

..And did they teach you that on the Basic Skills course you did last week..?

Bollocks, that only works if your bike has a certain amount of power. I spent MONTHS trying that on my bike because of silly twits like you who parrot wheelie advice for R1s.

Sorry guys, you have to dump the clutch on a full throttle. Only way to bring most 250 road bikes up.

As far as wheelies go, I've pulled like one on takeoff once, but quite often the front wheel lifts a bit off the ground when I'm thrashing it and I drop it into second.

And as for stoppies, my tyres are too crap, and it skids every time I try it... which is really dodgy cause if you don't get off the brakes fast she'll go down on you (not the good kind of 'going down on you').

Here's an awesome vid of a guy who knows how to ride his CBR250.

And here's a good thread about what can happen, and other advice.

Couple of things I've picked up - first, you cant be too sudden on the brakes, you gotta be hard but smooth. Second, you gotta have warm tyres... I've tried on cold on a FZR250, and no way would it work. I had to stick my boot down to stop it going over after the front locked up once

That guy is too good. His wheelies are too bloody awesome for a 250 though!

I want to have his great skillz.

Anyone know how hard it would be to wheelie a GSX250250F Across?

I thought the soundtrack was tragic.

Maybe you could fit some helium balloons in the helmet storage compartment to get the front up?

Keep an eye on the bolts holding the front of the bike together,
the tend to come loose,
with to much abuse.

HAAHAHAHAHAHHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHHAHAH AHAHAHAHAH

im sorry but i only just found this thread and shit me i spent the last 20mins reading thru it...

and pitty now i have to go to work damn, im going to re-read this again later.

At the risk of probably soundin stupid.

Top speed of a cibby 250 is 220k de-restricted. The engine does it quite easily, it just runs out of puff. My theory is carbs but I haven't the expense nor the desire to mod mine to find out.

They are geared to run to 180k using standard fitment sprockets and (having tested mine against one of those radar speed signs they have on trailers) the speedo seems pretty accurate. Although I find it hard to read dials on the cibby at that speed other than to get a feel for the general direction of the needle.

Using standard gearing they will run to the speed limiter at the top end of 5th gear, 6th is just for cruising.

They will wheelie quite easily in 1st and 2nd. The wheel will skip under power (12k rpm on my machine) fairly easily and you just need to bounce it a bit to bring it up with a bit of rearward balance.

Not tried it in any gear above 2nd as I have no balance for wheelies (fall over to the right). But I know people that can lift the wheel in 3rd. It should be technically possible to bounce lift it in a higher gear, but I dont have the bottle or desire to try - so I shall leave it in the theory till seen done dept.

With a different end-can on from standard you gain back the 5bhp flat spot at 12k rpm to give about 40bhp peak power/15 ft-lbs torque. The power curve is almost dead straight - it feels like riding a fuel injected bike with a linear gear box.

I could well believe the front end can come up at the top end of the speed limit but for myself I think it would have to be an aided lift some how. The gearing/power delivery/torque doesnt allow for a power lift at those kind of speeds.

For stoppies, I have double H pads on that suck when cold, so I've not been able to do them. Most of the time I end up with the front wheel skipping, but I suspect I'm not getting the weight forwards. Dont bother trying these on this bike as it does munt the forks somewhat and I dont really want to put in new seals again.
