wheelie related question

just a small question for you guys that do a lot of wheelies. when you're putting the front end back down, is it normal to experience headshake when the front wheel touches back down? only reason I ask is I keep experiencing this and I'm not sure if its normal or not. I know its something that usually will stop on its own, as it has for me so I dont panic about it, but it just makes me wonder.

bear in mind, I'm new to stunting and still have a lot to learn.

life is but a way of killing time until you die. why care how you live, just have fun while you can.

Depends, if you put the bike back down somewhat softly, with the bike not leaning, going straight, and the front wheel straight, head shake is not likely.
The most common time to experience it is when the front end comes down and the front tire is not in line with the direction of travel of the bike.
That's my experience anyway.

In my limited experience SVR is exactly right... Also, what speed are you bringing it up? I never really had this problem with my 500r (I assume that's what you're talking about)... Perhaps head bearings?

Hmm.... Never had that problem... Head bearings... Tire pressure perhaps... Comin' down at an angle or with the bars slightly tweaked... I have the tendency to pull the bars/wheel to the left... Even slightly tweaked when it comes down causes some shake...

Your wheel probably isnt perfectly striaght when it comes down if it jerks it violently straight. No big deal just hold on

Another thing to consider is how hard you are setting it down... I am a wheelie amateur so sometimes I come down fairly hard which magnifies the tweak of the bars...

If you can afford one, get a damper. That will help 10 fold.
Like already stated, set it down easier and more straight. Also, the slower you are, the less aggressive the head shake is.

ooooo, didn't catch that. I know of people fabricating there own bracket to fit one on bikes that don' have one, but I don't know if its worth the trouble.

never had a problem with shakes, keep the wheel straight and ya won't have probs. had 1 wobble where i had put a little too much weight on one foot peg and the bike had leaned a bit when i set the wheel back down and it kicked a bit, but no wobbles. keep it straight and make sure your head bearings are good and triple clamps are tight.

It simply comes from setting the wheel down not perfect in the direction of travel, as was stated before. It has nothing to do with the mechanical error. Just keep the wheel straight or get a damper, only 2 solutions.

2002 ZX6R, Shark Skinz, custom paint, Ignition advance plate, Shift kit, Yoshimura TRS Full race with Duplex header, K&N, 14/40 gear and sprocket, Ivans jet kit and Dyno tune for 103hp at the wheel. 110hp with 110 octane!

at high speeds, a damper might transfer the shake into a frame whobble. a good rule of thumb, throttle hard to take the weight and frequency out of the front before a tank slapper results. i've had a high speed tank slapper before, shat ma panties.

I have had a damper before getting into wheelies so at worst I get a half second jolt that tells me I set it down crooked Gotta love dampers


Dont even worry about it on a ninja 500

Everyone's advice sounds good on here and I agree with them. One question though, how fast are you going when you're pulling these wheelies?

Start at around 20 mph or so, no clutch. But that's w/my v twin too. Different bikes will be at different speeds in their said powerband.

Prolly not gonna happen that way with the EX500... Then again, I could get it off the ground and with Bob's much lighter weight (like half of my fat azz)... Could be possible...

I've wheelied the gf's 250... get rolling about 10 mph or so, pull in clutch, sit WAY back on pass seat, rev up to about 8-9 grand, and just drop the clutch and pull... get it up about a foot or so. Thinking the 500 should be able to do it too???
