PBR Steel Noise-Reducing Sprocket 2344 - 520 (manufacturer's ref: 2344G 16 18NC): a robust front sprocket designed for the final drive of roadsters equipped with 520. Designed to limit noise and improve chain smoothness, it is aimed at riders looking for a reliable part for road and intensive use.
The RSS system incorporates rubber injected into the bores to reduce vibrations transmitted by the chain, limit noise, and provide a smoother transmission behaviour. The rubber is formulated to resist detachment, which enhances durability during repeated use or long distances.
Designed for roadster motorcycles, the PBR 2344 sprocket is particularly compatible with the APRILIA TUONO 660 FACTORY (2025), APRILIA TUONO 660 (2025), and APRILIA TUAREG 660 RALLY (2025) models. Please check the required number of teeth and mechanical compatibility before installation.
