BDL Rear Drive Belt For Harley Custom Applications
BDL Rear Drive Belt: The Ultimate Final Drive for Custom V-Twins
The BDL Rear Drive Belt represents a partnership between Belt Drives Ltd. and Gates, the global leader in belt technology. Designed for Harley-Davidson custom applications, these belts are engineered to handle the massive torque and horsepower generated by big-bore Milwaukee-Eight, Twin Cam, and Evolution engines. Whether you are building a ground-up custom or upgrading a performance touring bike, BDL provides the most reliable connection between your transmission and the rear wheel.
Carbon Fiber Tensile Cord Technology
The “Poly Chain” technology used in these belts utilizes Carbon Fiber reinforcement instead of traditional polyester or aramid cords. This material science breakthrough offers several key performance advantages for custom builders:
- Zero Stretch: Carbon fiber does not stretch under load. This means that once your rear wheel is aligned and tensioned, it stays that way—eliminating the need for frequent maintenance.
- High Power Density: These belts can handle more torque in a narrower profile. This is essential for wide-tire kits where clearance between the belt and the tire is extremely tight.
- Exceptional Durability: Rated for high-output engines producing well over 150 HP and 150 ft-lbs of torque.
Precision 14mm Tooth Profile
BDL rear belts feature a precision-molded 14mm pitch (standard for Harley final drives). The teeth are jacketed in a durable, self-lubricating fabric that reduces friction, dissipates heat, and minimizes “belt whine.” This ensures a smooth, quiet ride and prevents the tooth-shear that can occur when high-torque engines are paired with inferior aftermarket belts.
Designed for Custom Versatility
Because custom builds often use unique gearing ratios and swingarm lengths, BDL offers these belts in an extensive range of sizes:
- Widths: 1-1/2″, 1-1/8″, 1″, 20mm, and 24mm.
- Lengths: Available in tooth counts from 125T to 139T to match your specific sprocket combination and axle-to-axle distance.
- Style: Features a clean, black-out look that integrates perfectly with both show bikes and performance “club-style” builds.
Key Specifications
- Reinforcement: Carbon Fiber (Poly Chain Technology).
- Pitch: 14mm.
