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.

• Material: steel (18NCD5 alloy)
• Number of teeth: 13
• Chain pitch: 420
• Version: standard, type 2107

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.

Compatible notably with:

• Aprilia RX 50 (2010)
• Derbi GPR 50 R Nude (2008)
• Bultaco Lobito 50 (2006)
