PBR Standard Steel Sprocket 426 - 428 (Manufacturer Reference: 426 12 18NC)
Designed by PBR based on experience gained in competition, this standard steel sprocket is aimed at riders looking for a reliable transmission part for their roadster. Machined from high-quality 18NCD5 steel alloy, it combines mechanical strength and wear resistance for an installation as an original replacement.
The design adheres to a strict manufacturing process aimed at minimizing friction between the sprocket, crown, and chain while delaying abrasion. Corrosion-resistant, this sprocket is suitable for common 125 cc configurations listed in compatibility (e.g., Benelli Leoncino 125, Keeway RKF 125, Mash Seventy Five), provided that the pitch and number of teeth on your motorcycle are verified.
Before ordering, check the reference and dimensions of your transmission for a confident installation. PBR delivers a robust replacement part designed to last on the road while meeting the demands of modern transmissions.
