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.

Abstract: A replacement neck assembly for a motorcycle modifies the motorcycle frame to accept a larger front wheel diameter than the factory original, the replacement neck assembly providing the replacement neck, an optional fairing mount, the replacement neck accepting a factory or modified triple tree, whereby the motorcycle frame can accept the large front wheel without affecting the operating height of the motorcycle.
