hi to everybody, I bought a new 2007 919 ,and after 1500 miles I still have a vibration that I think come from the motor. Is anybody had this problem before and what do you think it come from... thank you!

with the stock front sprocket they are buzzy at Interstate speeds. wht kind of vibration is it?

[fastguy]

Ît,a vivration that goes to the handle like a electrical chock.

[129CBRider]

Normal for the 919 if it occurs at about 75 to 80 mph.

If you buy a front sprocket with one more tooth (17), it will lower the rpms about400 and the buzz won't happen until about 85 to 90 mph.

You loose the ability to power wheelie but not too many people riding a 919 are into that.

thank you guys !

renthal bar'sGet renthal bars to eliminate the buzz not just move it then get 15/45 gears and you will power wheelie your @$$ off.

Add a tooth, get some better grips, wear good boots, add some Renthals, and consider some bar ends. But remember you're riding an inline 4 with its sleeves rolled up. Some buzz is expected.
