rode an ATV with one, and it got annoying after a while, maybe just because I'm not used to the setup.
This is a pretty ludicrous statement. "Use your thumb till the point where you have to use your wrist"?? Err... how are you using the twist grip?i can tell you right now...ive been riding quads for 6 years before i recently switched back to dirtbikes and thumb throttles SUCK!!!!! they get extremely tiring for your thumb till the point where you have to use your wrist. it may bey cool and different but i would definately would not reccommend it!
