PBR Steel Noise-Reducing Sprocket 2147G - 525 (Manufacturer reference: 2147G 17 18 NC): rear sprocket made of steel designed for 525 chain transmissions. Its design incorporates PBR's RSS (Rubber Sprocket System) technology, which integrates rubber injected into the perforations to limit vibrations and significantly reduce transmission noise.
This sprocket is aimed at riders looking for a durable solution to reduce transmission noise without sacrificing strength. Ideal for powerful roadsters: it is listed as compatible with machines such as the KTM 1390 SUPER DUKE R EVO, SUPER DUKE R, and SUPER DUKE GT (2025 - 1390 cm3). Installation and maintenance remain unchanged compared to a standard steel sprocket ā just check the 525 pitch and tooth compatibility before installation.
