| I have one on mind . . .
works a treat - easy to fit - if you have longer bars you might need some longer cables though as they are not quite long enough on mine!
It comes with 3 cams - I have the biggest one (least amount of turn) on mine - tried the others - this one works best for me.
Unlike the advice I was given by Pro-Twins the throttle feels fab - they said it would be too hard to twist - rubbish!!!
