Abstract: The present invention is directed to reducing the amount of exposed hydraulic lines and the like in a vehicle such as a motorcycle. Embodiments of the invention utilize the frame tubing to route the hydraulic lines through the fame to different parts of the vehicle. Different fittings are used to connect the hydraulic lines from the frame tubing to external lines. In accordance with an aspect of the present invention, an apparatus for routing a line through a vehicle frame tube comprises a line including an end portion configured to protrude from a side opening through a wall of the vehicle frame tube. The end portion of the line has at an end a fitting for coupling with an external line. A tube extension is configured to be attached to the wall of the vehicle frame tube around the side opening and to surround the end portion of the line. The tube extension is coupled with the fitting at the end of the line.

Abstract: Embodiments of the invention provide a bearing support for the primary drive shaft extension of a motorcycle or the like so that the main bearing support is as close to the drive mechanism as possible. In one embodiment, the shaft extension device comprises a shaft extension member configured to be attached to the shaft to rotate with the shaft. The shaft extension member includes a bearing surface disposed at a distance axially spaced from the shaft. A primary spacer is configured to be connected to the motor casing. A bearing is supported by the primary spacer to be axially spaced from the shaft and to contact the bearing surface of the shaft extension member to provide bearing support for the shaft extension member.

Abstract: The present invention is directed to a suspension mechanism that is built into the rigid frame members of a vehicle such as a motorcycle to provide a softer ride while preserving the clean look of the rigid frame. The vehicle has a wheel mount for a wheel, a steering head for a steering handle, and a vehicle frame. The suspension mechanism comprises a lower frame member of the vehicle frame extending from the wheel mount, and an upper frame member of the vehicle frame extending from the wheel mount and being disposed above the lower frame member. An upper frame arm of the vehicle frame extends from the steering head and is movably coupled with the upper frame member at a location between the steering head and the wheel mount. The upper frame member is slidable relative to the upper frame arm along an upper arcuate path centered around a pivot axis disposed between the upper frame member and the lower frame member.
