I agree, twist throttle is bad, the first time I rode with it on I pulled a wheelie and the throttle pinned wide open and I flipped it right on top of me.
Yeah there is one that has both. I think there is another comomany othe than moose. I had a mojave once with a twist. Hated it. Went up a 3ft rock ledge in a water crossing. Bike slipped, my hand came down, the throttle pinned and the bike shot out from under me. Never again will I own one.
