High-Tensile Carbon Fiber Technology

The secret to this belt’s longevity is its carbon-fiber-reinforced tensile cords. Unlike traditional aramid-style belts, carbon fiber offers significantly higher dimensional stability. This means:

• Zero Stretch: Maintains consistent tension over thousands of miles, reducing the need for axle adjustments.
• Exceptional Strength: Rated to handle the torque of Stage I and Stage II performance upgrades with ease.
• Efficient Power Transfer: Minimizes energy loss during acceleration, providing a more responsive throttle feel.

Quiet and Smooth Operation

Featuring a precision-molded 14mm pitch, the Drag Specialties belt is designed to mesh perfectly with your stock front and rear pulleys. The teeth are jacketed in a durable, self-lubricating fabric that reduces friction and heat. This specialized coating virtually eliminates the “belt whine” common in aftermarket belts, ensuring your ride is as quiet as it is powerful.

Built to Withstand the Elements

Whether you’re daily commuting or cross-country touring, your belt faces oil, UV rays, and road debris. This belt is manufactured from an advanced synthetic rubber compound that resists ozone aging and chemical degradation. Its robust tooth profile is also engineered to help eject small stones, preventing the punctures that are the leading cause of premature belt failure.
