Abstract
A motorcycle transmission (100) utilizes a shift fork (45), a shift collar (30) including a plurality of engagement teeth (30c) and a collar rib (30a) and a gear (34) (or one of the other six gears). The engagement teeth (30c) drive the teeth (34a) of the gear (34). A trap door (49), in combination with a threaded retainer (55), reduces axial play in shafts (37) and (75).
