Abstract
A shifting system is provided that includes at least one shift fork and shift collar. The at least one shift fork is axially movable on a shift rail. The at least one shift fork further has a second end with spaced side walls and a shift fork pin. The shift collar is axially movable on the shift rail between the spaced side walls of the at least one shift fork. The at least one shift collar has a shift collar pin. A biasing member is configured to bias the at least one shift collar against one of the spaced side walls of the at least one shift fork. A rotating shift drum has at least one shift guide profile that receives at least one of the shift fork pin and the shift collar pin to guide the at least one shift fork during a shift of the shifting system.
