I run 2 Rm 370s an A & a B and they both vibrate like hell , Modern bars with dampers will reduce the vibration a bit but i think its just patr of there Character :)

Vibration is part and parcel of the makeup of the RM370. Mine used send my hands to sleep and pump my forearms. Lets you know your alive.  ;D

A crank rebalance is the only way to sort this out.To move the vibrations out of the rpm zone where the engine spends most of it's life at.May pay to check that a  oversize/heavier/lighter piston has or hasn't been used.

Yup I agree the 370's will vibrate. My '78 400C has the rubber mounted pull back type bar clamps and still the vibes send your hands numb after a decent ride. I've had worse though, the fireblade I had would make my hands totally numb after 15 or so minutes of highway buzzing..I could never be sure if I had indicated unless I doubled checked the flashing light on the idiot panel and this was on a street bike!  ::)

There you go, its unanimous. As you know as per our chat that mine also vibrates. Could get good money down the adult shop with the vibrations it puts out!
