closed belt drives for Harley-Davidson

There's a drive system that, once installed, lets you forget about lubrication, adjustment, and regular maintenance – it's the enclosed poly-V belt drive. Unlike traditional open rear belt or chain drives, the enclosed belt drive operates within a completely enclosed, protected casing, shielding the belt from dirt, gravel, and moisture, while also protecting the user from moving parts. The poly-V (or multi-rib) belt design also provides greater load capacity and quieter operation than traditional toothed belts, making it an ideal choice for both everyday use and more powerful custom motorcycles. Our range includes enclosed poly-V belt drive systems for Harley-Davidson motorcycles, from complete kits – pulleys, belt, cover, fasteners – to individual components, if you only need to replace a specific part. The enclosed design is particularly popular for bagger and touring builds, where cleanliness and lubrication-free, long-term reliability are paramount. Quality enclosed belt drive systems are made from durable materials with precise manufacturing to transmit power quietly, cleanly, and reliably for a long time, with minimal maintenance requirements. Whether you're looking to replace an open chain drive or build a completely new, maintenance-free drive system, you'll find the enclosed poly-V belt drive that perfectly suits your motorcycle.
