PBR Steel Noise-Reducing Sprocket 2137 - 525 (Manufacturer Ref: 2137G 15 18NC): a transmission sprocket designed for riders seeking durability and quiet operation. Made from steel, it features a 15-tooth configuration suitable for 525 pitch chains and stands out with its noise-reducing version incorporating the RSS (Rubber Sprocket System).
The RSS process combines the strength of steel with a rubberized insert that helps to dampen shocks and noise transmitted by the chain, without compromising reliability in intensive use. Installation and replacement are carried out like a standard sprocket; please adhere to the alignment and torque specifications recommended by your manufacturer.
A product from the PBR brand, this sprocket is particularly suitable for roadsters and is compatible with models such as: KAWASAKI VERSYS 1100 SE (2026), VERSYS 1100 S (2026), and NINJA 1100 SX SE (2025).
