About this category

The slimline profile allows for a more compact fit within the primary case, ideal for Evolution, Twin Cam, and Milwaukee Eight engine configurations. Manufactured from high-strength materials, these open belts provide smooth and efficient power transmission, minimising energy loss due to friction. Compatible with a wide range of Sportster, Dyna, Softail, and Touring models, both stock and aftermarket. Direct installation facilitates chain-to-belt conversion without modifying the gearbox. Available in various widths and lengths to suit specific engine and clutch configurations.
