PBR Steel C45 Sprocket – Manufacturer Ref: 899 51 C45

Designed by PBR, a specialist in competition chassis, this 51-tooth C45 steel sprocket is aimed at demanding motorcyclists looking for a robust part for their final drive. With a black finish and standard 520 machining, it is a reliable option to replace your original sprocket on Cross and Roadster machines.

• Material: C45 steel, providing good mechanical strength for road and off-road use
• Number of teeth: 51 – suitable for gear ratio adjustments for torque/acceleration
• Chain pitch: 520 – standard mounting on the relevant transmissions
• Black finish with resistance to corrosion and abrasion
• Strict manufacturing and quality control, high-quality raw materials

The geometry and machining quality limit wear and help reduce friction at the sprocket-chain connection, resulting in a smoother final drive. This standard part allows for direct mounting and is particularly suitable for machines like KTM 690 SMC R (2026), STARK FUTURE VARG EX (2026), and CF MOTO 800 NK SPORT (2025) equipped with a 520 chain. Ideal for maintaining or enhancing your transmission without major modifications.
