I notice the 919 has alot of vibration around 5k (or anytime really). is it just a design flaw. is there something I need to check that I'm over looking? I never notice this vibration on any of my previous bikes.
If im not mistaken, the vibes are more aparent because the motor is a stressed member in the frame. Around 5k seems a be a pretty common spot to have it get "buzzy". I would says its mostly just the nature of the beast.
well I should have been more discriptive. the buzz thru bars doesnt bother me as much as the foot pegs.
Oddly enough, installing the Sato rearsets on my bike almost completely eliminated the foot vibes. You would think that the solid mounting pegs would transfer more.. but I think not having a long piece of metal sticking backwards to wobble back and forth and pick up harmonics is the reason why. The long piece of metal being the passenger foot pegs. I have them, but do not use them.
Install a set of alloy bars...and beware of thick gel grips, a large diameter grip will tire out hands quick. I agree with the rearset theory...I am installing Sato's this weekend. At idle you can actually see the passenger pegs vibrating. Hope that helped.
And, my $.02 on the 919 vibration. Just don't ride in the 5k range.
well I think it vibes in all ranges but more in the 5k range. really I flog the **** out of it. being used to 600 sport bikes (R6 mostly) i bounce the 919 off the rev limiter quite offten. my friend used to ride a bandit and I rode it once. he said I could change gears on it but I was used to hitting 10k and shiffiting or keeping it up around 8k. he thought I was afraid to change gears lol
