The PBR crown ref. 820 43 C45 is a transmission part specifically designed for demanding riders. Machined from C45 steel and coated in black, it fits transmissions equipped with a 520 pitch chain. Its 43 teeth provide a performance/durability compromise suitable for off-road and road practices.
Born from PBR's competition experience, this crown is aimed at motorcyclists and teams looking for a robust part to equip their rear transmission. It is suitable for Quad, Cross, and Roadster environments and can replace the original crown when the specifications (520 pitch, 43 teeth) match.
Examples of compatible machines according to these specifications: SHERCO 500 SCF (2020), BETA RR 480 4T (2020), GAS GAS EC 250 RACING SIX DAYS (2020). Before installation, check compatibility with your model (sprocket carrier, spacing, and chain adjustment).
