PBR Steel Standard 2177 - 428 Output sprocketRef : PBR00707A / 1077596002

The PBR 2177 steel sprocket (428) is a transmission part built to last on roads and loose terrains. Designed by PBR from experience gained in competition, this standard 14-tooth sprocket offers a reliable solution to replace a worn sprocket and restore a perfectly adjusted chain.

• Manufacturer reference: 2177 14 18NC
• Type: PBR standard steel sprocket 2177
• Material: 18NCD5 steel alloy
• Number of teeth: 14 (pitch 428)
• Applications: Cross and Roadster universes

The composition in 18NCD5 and strict manufacturing control limit wear and corrosion while maintaining a uniform tooth profile to reduce friction with the chain. PBR relies on proven industrial processes to ensure consistent tooth geometry, essential for smooth transmission and predictable behavior during acceleration and deceleration.

Easy installation as a direct replacement for the original sprocket (check compatibility regarding pitch and number of teeth). Particularly suitable for small displacements listed in top compatibility: YAMAHA TT‑R 125, YAMAHA YBR 125 (various years). An ideal part for riders seeking a robust transmission and effective chain maintenance.
