Can you put a 110cc engine in a x1 pocket bike?

Yes a 110cc semi or non auto trans will fit into the x-1. there is plenty of room for starter, shifter, case, and cylinder head. The motor sits right in between the rear frame bars to get more clearance between the the head and front forks. If positioned just right the case sides will even line up with the faring plastic and almost look like it was ment to be. the single front frame bar and motor base plate can be removed and height adjusted to the base plate on the 110cc motor. We even found room upfront for a Oil cooler, and the battery holder stayed in the factory position. Next is a turbo.
