EVO-9SF is the work horse of belt drives. With over 50,000 kits running on bikes today you can be reassured this drive can outlast and out perform the competition. Our one-piece 6061-T6 polished billet motor plate locks the tranny and engine together. All of these kits include a 3Ē wide belt drive unit with polished pressure plate, double row sealed mainshaft bearing, polished aluminum side plate and pulley covers and a complete "Competitor Clutch" with Kevlar plates. For installation in wide frame/ tire applications, choose the appropriate insert. Kits come with an oil filter mount centered in the motor plate. The kit allows the oil lines to be hidden out of the way. For Softail models from 1990 to 2006.
