Based on PBR's competition experience, the standard steel sprocket 238 - 420 (manufacturer reference 238 36 F) is designed for demanding motocross riders looking for a solid and reliable part for their transmission. Engineered to withstand the challenges of off-road riding, it combines meticulous metallurgy and a discreet black finish to blend seamlessly with both prepared and stock machines.
The 18NCD5 alloy used ensures excellent resistance to corrosion and abrasion, while the strict manufacturing process limits dimensional variations and unnecessary play. The result: a consistent tooth profile that reduces friction and premature wear on the transmission when engaged on soft or rocky terrain.
Practical compatibility: ideal for the listed motocross machines (e.g., HONDA CRF 110 F JE02 2025-2026, CRF 70 F DE02 2012). Check the pitch and number of teeth to adapt it to your setup.
