t is common knowledge that a belt drive primary provides advantages & service that a standard chain drive

primary cannot. For dependable, high-performance, long lasting service nothing beats a modern Primo

pri-

mary Belt Drive! A long standing tradition of ”Quality & Performance” has made Primo

Belt Drive systems

the most popular in the world! That same quality & performance is now available in the Brute III EXTREME

belt drive for Evolution Big-Twin and Twin Cam motorcycles (fully enclosed primary drive). The wet clutch night-

mare is over, no more leaky primary, no more draining the primary for inspection or maintenance. Carefully

read & follow these instructions for a quick, convenient installation. If you have questions call (562) 907-2600.

IMPORTANT SAFETY NOTICE....

When performing any motorcycle work such as installing a belt drive, secure the motorcycle in an upright position
