Description

Experience superior power delivery and enhanced clutch engagement with this premium 1-5/8" 8mm belt drive kit from Belt Drives Ltd. Designed as a direct bolt-in application, this system replaces your stock primary drive with a robust, high-efficiency solution. The innovative lockup clutch design applies extra pressure to the clutch plates, ensuring positive engagement without any clutch slippage, even under aggressive riding conditions. This means more power directly to your rear wheel when you need it most. The kit features a durable 41.3 mm (1-5/8") width and includes a precision-machined front pulley, the belt, a high-strength clutch hub, and a clutch basket. The aramid clutch set, comprising two half plates, four full plates, and five steel drive plates, is built for longevity and consistent performance. Crafted from a combination of steel, DuPont™ Kevlar® Fiber, and 6061-T6 Billet Aluminum, every component is engineered for maximum durability and lightweight strength. Made in the USA, this motorcycle primary belt drive provides a significant upgrade in both performance and reliability, all while maintaining a quiet operation thanks to the Quiet Clutch and ball-bearing lockup design pressure plate, without increasing lever pull effort.
