12-1101-20 Off-set Front Pulley Inserts

These 3 1/2-inch diameter offset front pulley inserts from Rivera Primo are engineered for late-style Brute IV 3-inch wide belt pulleys. They are a vital component for custom builders looking to offset the transmission to clear wide rear tire setups. Each insert is supplied with two dowel pins and five countersunk screws for installation. Rivera Primo is a staple in the American V-twin industry, known for durable primary drive solutions. When installing, builders must also source the corresponding motor nut, special washer, and outside guide to ensure the belt drive system is correctly spaced and aligned for reliable performance.
