A motorcycle power transmission assembly including an engine, a transmission, a drive assembly, and a starter assembly. The engine includes a crankcase, and the transmission includes a transmission case coupled to the crankcase to define an engine-transmission assembly. The drive assembly includes a drive housing coupled to the engine-transmission assembly to define a drive chamber. The drive housing including an opening, and the drive assembly further includes a starter gear. The starter assembly is mounted to the drive housing and includes a nose portion that extends through the opening. The nose portion includes a pinion gear adapted to engage the starter gear.

Starter assembly for a motorcycle engine

A primary housing for a motorcycle engine includes an inner housing that defines internal coupling apertures, transmission coupling apertures, and external coupling apertures. Internal fasteners extend through the internal coupling apertures and the transmission coupling apertures to couple the inner housing to the crankcase and the transmission. An outer housing defines coupling apertures that align with the external coupling apertures and fasteners extend through the coupling apertures, through the external coupling apertures, and into the engine crankcase to couple the inner and outer housings to the crankcase. A resonant damping device is rigidly or moveably coupled to an anti-node region of the outer housing to reduce noise emissions from the outer housing during engine operation.
