The primary shaft is supported by a support bracket, the support bracket being connected to the crankcase. An air inlet is adapted to permit entry of cooling air into the transmission chamber, and an air guide is configured to direct a flow of cooling air into the transmission chamber along the drive belt, the air guide being connected to the support bracket.
