RENTHAL Standard Steel Sprocket 259 - 420 (manufacturer's ref: 259--420-15P): engine sprocket designed for Offroad and Roadster practices. Designed by Renthal, a recognised specialist in motorcycle transmissions, this 15-tooth sprocket with a 420 pitch combines precision machining and alloy material for good wear resistance while minimising unnecessary weight. Ideal for those looking for a reliable part for the primary transmission of their small enduro or motocross bike.
This Renthal sprocket fits into drivetrains where robustness and precision of the tooth profile are essential. It is a direct replacement for original components on many models 70–85 cc; compatible notably with HONDA CRF 70 F (DE02) and HONDA CR 85 R (HE07) 14/17 and 16/19 depending on the setup. Before installation, check the chain pitch, number of teeth, and centre distance to ensure compatibility. Chain installation and adjustment recommended by a professional if necessary.
