2005 BCR with mucho vibration felt through the bars...

Any pointers on sources of vibration in my buddy's 2005 R1100S ? - I suggested he check engine & exhaust mounts/rubbers. I rode it this week and there is definately a lot more vibration felt at the bars between 3000-5000rpm which I can see would be really annoying on a ride.

Would probably be worth looking at balancing the throttle bodies as this can often make a significant improvement. We all know the 11S isn't exactly the smoothest engine ever made, but measures can be taken to help it on its way.

Also, engine's mileage can make a difference too - I've found that bikes with upwards of 15k miles on tend to be smoother, but of course that's no figure set in stone.

Hope he gets sorted at any rate.

Hi
First check that the bike is running right. Valve clearance and throttle body sync etc. then if still bad vibes check mounts. There is a spar on the frame under the gearbox which has been known to fracture.
All the best

Thanks I will investigate these.
