A recent addition to the Primo Belt Drives line-up is an ultra narrow open belt drive designed for 1990-2006 Evo & Twin Cam Softails®.
This 11mm kit features a 1-3/4″ wide “dense pack” Kevlar Polychain® Super Belt. This combination has been tested to withstand horsepower loads in excess of 150 H.P. The Slimline™ belt drive uses a one-piece motor plate which helps to add rigidity to the frame by firmly connecting the motor and transmission together.
Two kits are available with either a billet aluminum outer guard that covers the outer pulleys or a faux carbon fiber outer guard that fully covers the belt and pulleys for added safety & pleasing aesthetics. In addition, the motor plate is machined for a center mount oil filter & also ready to accept optional mid-controls (part # 2084-0504) which are single fulcrum and include both the shift & brake assemblies with a designer master cylinder.
