S&S Cycle Rear Drive Belt For Harley Custom Applications
S&S Cycle Rear Drive Belt: The Gold Standard for Custom V-Twin Performance
When building a custom motorcycle or upgrading a high-torque V-Twin, the final drive belt is often the weakest link. The S&S Cycle Rear Drive Belt is engineered to eliminate that weakness. Developed to meet the rigorous standards of S&S Cycle, these belts are designed to handle the massive horsepower and “shock loads” of performance engines that would easily snap or stretch a standard OEM belt.
Carbon Tensile Cord Technology
The heart of the S&S belt is its Carbon Fiber reinforcement. Unlike traditional polyester or aramid cords, carbon fiber offers superior dimensional stability. This means:
- Zero Stretch: Eliminates the need for frequent tension adjustments and prevents “belt slap” against guards or frames.
- Increased Power Transfer: More energy is transmitted directly to the rear wheel rather than being lost to belt deformation.
- Extreme Strength: Provides up to twice the tensile strength of standard aftermarket belts, making it essential for 124″+ engine builds.
Advanced Tooth Profile and Material
These belts utilize a modern 14mm pitch (or application-specific profile) with precision-molded teeth. The teeth are jacketed in a specialized, low-friction fabric that reduces noise and wear on your pulleys. The high-temperature rubber compound remains flexible in cold weather while resisting the “softening” and tooth-shear that can occur during high-speed summer touring.
Engineered for Custom Applications
S&S Cycle offers these belts in a variety of lengths and widths to accommodate wide-tire kits, custom swingarms, and unique gearing setups. Whether you are running a 1-1/8″, 1-1/2″, or the modern 20mm/24mm widths, S&S provides a belt that fits your custom geometry perfectly while offering a clean, “black-out” aesthetic that complements any build style.
