About This Product
This BDL 1-1/2 inch primary belt drive kit is a classic choice for Knucklehead and Panhead owners looking to simplify their drivetrain. Featuring an 11mm pitch, this kit is designed for closed primary applications and is strictly for kickstart-only models. The kit includes the pulleys and the belt, featuring a 47-31 drive ratio that works perfectly with your stock clutch. It fits 1937 to 1947 Knuckleheads and 1948 to 1954 Panheads. By eliminating the primary chain and oil bath, you get a cleaner, quieter, and more reliable setup. Please note that this kit does not include an idler and is intended for use with the original clutch components.
Manufacturer part number: 47-31TK-1.
