Default cause front to shimmy a tad?

I noticed when at the track at around 120-130mph the front would wobble a little bit. Every had that? Anything under that never felt it. Just trying to figure out since if weigh so little I can put enough weight on the bars to push it down like some of the bigger guys.

are you WOT?
If you dont have much of the tire on the ground it'll shake a bit.
or does it feel like an out of balance tire?

Check your tire for cupping. I get what I'd call a slight vibration over about 100mph but nothing I'd call an actual wobble or shimmy as the bike and front end is still rock solid.

The front tire is brand new or newer(maybe 500-800 miles) and was balanced. So that is perfect. I was at at full wot. If I got off it and back on and pushed kind of hard it seemed to go away. Maybe the tire was coming off the ground a bit. I am only 130lbs. I tuck really really hard under the windscreen so most body weight is at the tank or back more

sounds like what red is sayin is prolly true then... you could fix this issue with a stabilizer..

I track mine quite a bit. If there is a suspension tech there, pay the meager fee to have them set up your suspension properly for your weight, etc. A good stabilizer is helpful too. Took care of mine for the same problem.
