BDL Gates Final Drive Belt
BDL Gates Final Drive Belt: Unmatched Strength and Precision
When it comes to transferring power to the pavement, the BDL Gates Final Drive Belt stands alone. This collaboration combines BDL’s decades of V-Twin drivetrain expertise with Gates’ world-renowned Carbon Fiber technology. Designed as a premium upgrade for stock Harley-Davidson motorcycles and custom builds, these belts are engineered to withstand the extreme torque pulses and shock loads of high-displacement engines without stretching, snapping, or losing efficiency.
Carbon Fiber Tensile Cord Advantage
The “Poly Chain” technology utilized in these belts replaces traditional aramid or polyester cords with Carbon Fiber. This material science breakthrough offers several key performance benefits:
- Zero Stretch: Once the initial tension is set, carbon fiber belts do not stretch. This eliminates the need for frequent rear-axle adjustments and ensures perfect wheel alignment over the life of the belt.
- Superior Power Density: The high tensile strength allows for a narrower belt (such as 20mm or 24mm) to handle more horsepower than an older, wider 1-1/2″ aramid belt.
- Compact Efficiency: Ideal for wide-tire conversions where clearance between the belt and the tire is critical.
Patented Tooth Profile and Durability
The BDL Gates belt features a specialized 14mm tooth profile (or application-specific pitch) that is precision-molded to resist “tooth shear.” The teeth are reinforced with a rugged, low-friction fabric jacket that protects against wear and significantly reduces the “whine” often associated with high-performance secondary drives. Furthermore, the synthetic rubber compound is highly resistant to oil, road chemicals, and extreme temperatures, preventing the cracking and dry-rot that leads to premature failure.
Fitment and Selection
These belts are available in a wide array of lengths and widths to fit almost any Harley-Davidson application from 1980 to the present:
- Widths: 1-1/2″, 1-1/8″, 1″, 20mm, and 24mm.
- Lengths: 125T through 139T to accommodate various pulley combinations and swingarm lengths.
- Compatibility: Direct replacement for OEM Harley-Davidson part numbers.
- Origin: Proudly manufactured in the USA.
