Our EVO-900SF is the drive for people that would like the comfort and reliability of an outboard bearing support. This drive was designed with the same ideas of our Top Fuel Street drive the TF-2000. This drive has all the components of the EVOľ9S but with a strong billet outer bearing support to help minimize flex in the motor plate for high horsepower motors. This drive also includes our oil filter relocation kit so you can clean up the look of your bike by hiding your filter and oil lines on and behind our belt drive. Fits 1990-2006 Softail models.
