1. A motorcycle comprising:
- a frame;
a rear wheel rotatably coupled to the frame;
an engine supported by the frame and configured to drive the rear wheel, the engine having a crankshaft; and
a compensator assembly coupled between the crankshaft and the rear wheel and configured to dampen impulse loads between the crankshaft and the rear wheel, the compensator assembly having,a shaft extension rotatably fixed with respect to the crankshaft,an input member rotatably fixed and axially slideable with respect to the shaft extension, the shaft extension and input member forming a first interface therebetween,an output member driven by the input member with a torque-buffering interface, anda retainer rotatably fixed to the crankshaft and configured to axially retain the input member and the output member thereto, the retainer and output member being rotatably coupled to one another forming a second interface therebetween, and wherein the retainer includes a passageway extending between a distal end of the retainer and at least one of the first interface and the second interface.

Abstract
The present invention provides a compensator assembly for use in a motorcycle. The compensator assembly includes an input member, and an output member driven by the input member through a torque-buffering interface. The compensator assembly also includes one or more lubrication passageways formed therein extending between a distal end and one or more interfaces to provide lubricant thereto.

26. A motorcycle comprising:
-
a frame; a rear wheel rotatably coupled to the frame; an engine supported by the frame and configured to drive the rear wheel, the engine having a crankshaft defining a crankshaft axis; a compensator assembly to dampen impulse loads between the crankshaft and the rear wheel, the compensator assembly having, a shaft extension rotatably fixed with respect to the crankshaft, an input member rotatably fixed and axially slideable with respect to the shaft extension, the shaft extension and input member forming a first interface therebetween, an output member driven by the input member with a torque-buffering interface, a retainer rotatably fixed to the crankshaft, the retainer and output member being rotatably coupled to one another forming a second interface therebetween, wherein a distal end of the retainer defines a pocket, and wherein the retainer includes a passageway extending and in fluid communication with the pocket and at least one of the first interface and the second interface, and a retention bolt coupling the retainer to the crankshaft, the retention bolt having a head portion with a substantially conical outer surface, and wherein at least a portion of the conical outer surface is positioned within the pocket; and a cover at least partially encompassing the compensator assembly therein, the cover having a plurality of ribs forming an apex that is vertically aligned with the crankshaft axis.
