Athena Final Drive Gear '89-'11

15 x 50 (22% Increase) or 14 x 42 (33% Increase)

(Please make a selection in the drop down menu!) 

Helical Cut design allows for quiet gear operation compared to straight cut!

Top Speed increase : 5-7 MPH with 15 x 50, and 6-12 MPH with 14x42

This is an easy install, however, we would recommend  replacing the bearing at this time and make installation a breeze along with maximizing performance!
