What causes headshake?

I think I've experienced the common 954 headshake I've heard these bikes are prone to. Leaned over in a corner, hit the apex applied throttle and the handlebars start going back and forth. I was thinking about it and figure it was because when you apply throttle, the front end will get lighter and upset the suspension.....am I correct in my thinking? What can I do to fix this issue? I know a steering damper will help but that doesn't exactly "fix" the problem, it just masks it. Is there something specific about the 954 that causes this?

The most common cause is rider input.
Are you completely relaxed on the bars?

I'm not sure....I would say that since this is my first sportbike (not first motorcycle) I might be a little tense I guess. Could it really be that simple? Is it possible to countersteer in a hard corner and still be completely relaxed?

Rubbish, they don't _need_ a damper.

Because of my weak right hand I tend to hang on only to the left bar which tends to upset the bike on the exits if I get lazy.
What do you mean by "countersteer" in a corner?

Sure, but how much headshake were you experiencing before you fitted the damper?

Re: What causes headshake?

only when the front gets light. Ok if you stay out of it you don't need one.

Even at full noise on the race track you don't need one.

What do you mean by "countersteer" in a corner?
By countersteer I mean in a right hand turn you are putting pressure on the righthand bar. And vice versa.

Re: What causes headshake?

For some more info, when I was getting these headshakes it was on a highway on ramp with long sweeping turns.....it didn't feel like I was on the throttle too hard, but again, I don't have very much experience on these bikes.

What kind of weight is the suspension set up for stock? I'm about 185-190 lbs. with full gear.

Get your front wheel off the ground and check bearings
