PBR standard steel sprocket 1252 - 520, designed for demanding riders seeking durability and consistent transmission. Born from PBR's experience in competition, this sprocket is intended for Cross and Roadster machines requiring a 17-tooth sprocket with a 520 pitch. Its construction from 18NCD5 steel alloy provides high resistance to wear and corrosion, useful in any riding conditions.
This sprocket is suitable for riders who want to maintain a reliable drivetrain and limit abrasion on the chain and sprocket. It promotes reduced friction thanks to its material characteristics and treatments, without altering the original behavior of the transmission.
Examples of common fits: GAS GAS SM 700 (2026), KTM 690 SMC R (2026), HUSQVARNA NORDEN 901 EXPEDITION (2025). Please check the pitch and number of teeth before ordering to ensure compatibility with your transmission.
