ABSTRACT:
A motorcycle reverse gear transmission that precludes inadvertent shifting into a forward gear when in reverse and inadvertent shifting into reverse when in a forward gear. The reverse gear transmission requires the forward ratio gears to be in neutral before shifting into reverse; during shifting, the apparatus locks the forward gears in neutral and then engages the reverse gear. The forward ratio gears are unlocked from neutral after the reverse gear is disengaged.
