PBR Standard Steel Sprocket 2107 - 420 (Manufacturer Ref: 2107 13 18NC)
Designed by PBR drawing on its competition experience, this standard steel sprocket 2107 is aimed at urban users looking for a robust and precisely machined part for mounting on 420 transmissions. Its 13-tooth configuration corresponds to common setups for 50 cc engines and offers a suitable gearing ratio for city journeys.
The 18NCD5 alloy ensures good resistance to corrosion and abrasion, and the part benefits from a strict manufacturing process to ensure precise tooth geometry and limit friction against the chain. PBR thus offers a sprocket suitable for regular replacement, compatible with many mopeds and small displacement bikes equipped with a 420 transmission.
