Have a new '12 450. Bike pulls hard, runs great BUT the bike will not ride at a constant speed. I understand the bike is designed for racing and its accelerates great but when trying to cruise at a constant speed the bikes lurches to the point it wants to buck me off. I think something is wrong with the TPI. My dealer has remapped the bike to some retarted acceleration curves as they say "it's rider error and the bike it to violent for me". Not happy with them. Their map is dirt and it still does the same thing.

Acceleration curves don't have anything to do with the bike not riding at a constant speed. I damn near got whip lash riding back to the pits.

Bike has about two hours on it.
