ZF Sprockets Rear Sprocket 39T – Honda XADV 750

The ZF 39-tooth rear sprocket is engineered as a performance drivetrain component for the Honda X-ADV 750 and Forza 750. Carefully crafted from high-strength aluminium alloy, this sprocket offers excellent strength-to-weight ratio while reducing unsprung mass for improved responsiveness. The 39T configuration slightly alters the final drive ratio for a modest shift toward torque at the rear wheel.

Machined with precision to match the factory bolt pattern, chain pitch (520 series), and seating geometry, the ZF sprocket ensures a direct-fit installation without requiring modifications. Surface finishing (anodisation or color coating) provides corrosion resistance and maintains aesthetic appeal over time. It’s ideal for riders who want a balance between performance, durability, and style in their drivetrain components.

When installing, it’s recommended to check chain alignment, torque settings, and use new mounting hardware or torque washers where applicable. Since the 39T is one tooth higher than the more common 38T, you may notice a slight change in engine rpm behavior under load—depending on rear gearing, rider weight, and use scenario.
