A supercharged motorcycle is disclosed and broadly includes a motorcycle and an air induction system. The supercharged motorcycle includes a case that partly houses a drive train of the motorcycle within a first case compartment and a wet belt drive of the air induction system within a second case compartment. The wet belt drive incorporates a toothed belt that enables a slip mechanism of the wet belt drive for protecting the motorcycle engine. The two adjacent compartments of the case fluidly communicate and are configured such that the wet belt drive can be compactly assembled onto the motorcycle.
