Abstract
Embodiments of the invention facilitate shifting by reducing forces on certain shifting components and includes a snowmobile comprising a chassis, an engine supported by the chassis, a drive train operatively connected to the engine, the drive train comprising a reverse sprocket assembly functionally coupled to an upper sprocket assembly, a jackshaft rotatable within the upper sprocket assembly, and a pinion operatively connected to the jackshaft and selectively positionable axially along the jackshaft to a first position that engages the upper sprocket assembly to translate the snowmobile in a forward direction or to a second position that engages the reverse sprocket assembly to translate the snowmobile in a reverse direction.
