ZF Sprockets Rear Sprocket 43T Suzuki GSR 750 / Yamaha MT03 / R3

The ZF Rear Sprocket 43T (part number ZFD-486-43-GLD) is a premium drive component engineered for performance motorcycles from Suzuki and Yamaha. With 43 teeth, this sprocket is designed to match the 520-pitch chain commonly used on bikes like the GSR 750, MT-03 and R3, allowing for direct fitment and optimized transmission geometry.

Manufactured from high-grade aluminium alloy and finished with an anodised gold coating, it offers an ideal combination of strength, durability and reduced weight compared to many stock steel sprockets. The precision machining ensures accurate bolt-pattern alignment, correct chain engagement and consistent performance under load. In riding conditions—whether spirited street riding, occasional track use or everyday commuting—this sprocket supports smoother power delivery, more immediate throttle response and durability over time.

Since the tooth count aligns with the stated model fitment, its gearing retains the stock ratio while introducing upgrade quality materials and finish. Installation typically involves removing the rear wheel, unfastening the original sprocket, fitting this replacement unit with fresh bolts (if recommended), verifying chain alignment and tension, and then re-torquing to specification. Riders seeking both style and substance in their drivetrain upgrades will benefit from this ZF unit.
