Idk im not a dirtbike guy and always have trouble with the twist but think it would be fun but could see the problems with it going up hills, I am a horrible hill climber as it is. If you thumb gets tired they do have extenders to give you more leverage. I would really like one my thumb cramps up really bad and sometimes i cant give it gas when it needs it becuase my hand turns numb and i have to stop for a second.
