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.

A shaft extension device for a drive mechanism having a shaft and a casing having an outer shape and an arrangement of outer apertures, the shaft extension device comprising:
- a shaft extension member configured to be attached to the shaft to rotate with the shaft, the shaft extension member including a bearing surface disposed at a distance axially spaced from the shaft;
- a primary spacer configured to be connected to the casing, and to have identical outer shape and arrangement of outer apertures as the casing;
- and
- a bearing 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.
A shaft extension device for a drive mechanism having a shaft and a casing, the shaft extension device comprising:
- a shaft extension member configured to be attached to the shaft to rotate with the shaft, the shaft extension member including a bearing surface disposed at a distance axially spaced from the shaft;
- a bearing support member having a bearing support surface axially spaced from the shaft;
- and
- a bearing supported by the bearing support surface of the bearing support member 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;
- wherein the shaft extension member comprises an outer surface pattern disposed distal of the bearing surface which is configured to be substantially identical to an outer surface pattern of the shaft.
