ABSTRACT:
A motorcycle frame is formed of tubular members which are hollow to provide a reservoir for oil used to lubricate the motor of the motorcycle. Fittings are provided within the tubular frame for receiving an oil filler cap, an oil spill hole, an outlet to the oil pump, an oil return inlet, an oil drain, and a crankcase vent. The seating area of the motorcycle frame is dropped closer to the ground due to the elimination of the oil reservoir normally located below the seating area of the frame, while incorporating a dampened rear wheel swing arm frame.
