Abstract: The hydraulic drive powered endless track drive motorcycle is a track cycle comprising a front track assembly, a rear track assembly, a power plant, and a frame. The front and rear track assemblies use an endless track circulating around a driven sprocket, bogie sprockets, and idlers to distribute the weight of the vehicle and provide greater traction than a tire would provide. The track assemblies are driven by hydraulic motors that receive pressurized hydraulic fluid from a power plant mounted to the frame. The power plant comprises an internal combustion engine driving a hydraulic pump and a hydraulic expansion tank. A seat is mounted to the top of the frame. The front track assembly is steerable using handlebars and a suspension system pivotably mounted to the front of the frame.

Abstract: A monoshock mount assembly allows conversion of the rear suspension system of a motorcycle from any existing configuration to a monoshock configuration that uses a single shock absorber. The monoshock mount assembly replaces factory-standard frame and suspension components. A body mount assembly attaches to existing attachment points of the motorcycle frame and provides structural support for bodywork, electrical and suspension components, and Other components. A swing arm pivotably attaches to the motorcycle frame and provides a lower shock mount, which may be offset from the centerline of the motorcycle. An upper brace attaches to the same attachment points as the body mount assembly and provides an upper shock mount that cooperates with the lower shock mount to mount the single shock absorber in a position where the shock absorber can operate normally without contacting motorcycle components supported by the body mount assembly.
