Abstract: Braking arrangements for inhibiting pedals of a pedal drive system for a watercraft from rotating when an assist drive train of the pedal drive system is activated are provided. Method of preventing pedals of a pedal drive system for a watercraft from rotating when using an assist mode are provided.

Abstract: The present invention provides a motorcycle including a front wheel, a rear wheel, a frame supported by the front and rear wheels, a crankcase including a first interface portion and a first passageway exposed to the first interface portion, a reservoir located remotely from the crankcase adapted to contain a lubricant, and a transmission case supported by the frame and including a second interface portion and a second passageway exposed to the second interface portion. The second passageway is in fluid communication with the reservoir. The first interface portion is coupled to the second interface portion. The first passageway is in fluid communication with the second passageway. The first and second passageways provide fluid communication between the reservoir and the crankcase through the first and second interface portions.

Abstract: 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.

Abstract: The present invention provides a transmission case assembly adapted for use with a motorcycle. The transmission case assembly includes a transmission case having a gear chamber adapted to contain a lubricant and generate a lubricant-laden mist during operation of the motorcycle, and a breather chamber in fluid communication with the gear chamber. The breather chamber is adapted to separate the lubricant-laden mist into lubricant and vapor and drain the separated lubricant into the gear chamber. The transmission case assembly also includes a transmission case cover coupled to the transmission case. The transmission case cover includes at least a portion of a passageway in fluid communication between the breather chamber and ambient air outside of the transmission case assembly. The passageway is adapted to exhaust the separated vapor outside of the transmission case assembly.
