Does anyone have problems with vibration through the throttle on a CBR 600 F1? My hand doesn't take long to go numb and the last time I travelled to Manchester from Plymouth I had to stop three or four times to give my right hand a rest! I normally would have got there with just the one stop at Strencham Services, but that was on my old BMW that I owned before buying the CBR. Love the bike but the vibration is spoiling my ride! Any suggestions gratefully received!
