I have a 07 gsxr1000 and I can feel a irregular vibration where what feels like the front of the bike. The best way for it to be noticable is to coast in neutral or squeeze the clutch to rid any engine vibes. While coasting and the bike is straight and upright, this is when the small but irregular vibes most noticable. While coasting I'll weeve back and forth( like the typical weeve people do to supposely warm up your tires) and the vibes almost go away the more the bike is leaned over. As the bike returns back upright, the vibes regain their strongest. Now this isn't a crazy vibration but its there and its not normal. I've checked for residue of a missing wheel weight on my front tire but it seems there isn't one missing. Everything appears to be tight and normal. On my recent trackday I have a feeling an incident may have created these vibes. I was turning into the bowl at full lean and had someone pass me in the apex. This person drove into my line infront of me and I got spooked and applied the front brakes. I used a little too much brake and my front tire made a "chirp" and my steering jarred hard for a split second. After this incident, I think I can remember my front end feeling slightly different. This leads me to believe possibly my front tire may have deformed and is now not perfectly round? What do you think?

Loosen the triple clamp pinch bolts then retorque them to spec. You likely twisted the forks in teh triples a little. Or maybe your tire was never round in teh first place and you just hadn't noticed...

Check the alignment of the rear wheel to the swingarm as well. If it's off from adjusting the chain, it could translate itself to the front.

How many miles on the front tire?

A drive chain that is too tight or has some binding links can cause similar symptoms.

Front tire probably had a few hundred street miles on it and a trackday when I noticed it. They are Dunlop Qualifiers.

I'll check that this weekend.

I just had some heli bars installed so I believe this would have been done already. And its still there.

Nothing seems to be wrong or out of alignment. I guess its just the tire.

my G/Fs 750 has a vibration in the front too. shes always complaning about it. i rode it the past few days and i can see why she she hates it. it puts my hands to sleep and i noticed that its actually making the tire wear funny. almost cupping. ive checked the tire press on her bike numerous times ands its never really needed it. i thought it was the warped rotor she had so i changed it. it helped.. especially with the braking problems (pulsing) but there is still something there.
