I don't know about that. I drove a small race car that used a snowmobile engine and CVT, although it worked really well in the race car, and of course in snowmobiles, I think the way it reacts to changes in throttle would be scary on a bike. When you back off throttle there isn't much, if any, compression braking, the engine rpm goes down very quickly unless you keep the throttle partially open, then when you roll the throttle back on the CVT hunts momentarily for the proper ratio. This delay, although very short with a well tuned system, might be unsettling on a motorcycle. When I drove that race car, I never had the throttle less than half, even under braking, to keep the CVT ready for throttle up. It worked well for the race car, but again, I don't think I'd like it on a bike.
