PBR Steel Noise-Reducing Sprocket 2344 - 520 (Manufacturer's reference: 2344G 17 18NC)
Designed for roadsters and demanding motorcycles, this 17-tooth PBR 2344 steel sprocket fits 520 pitch chains. Its design incorporates the RSS (Rubber Sprocket System): machined perforations house injected rubber that limits vibrations and dampens transmission noise without compromising the strength of the teeth.
Ideal for replacing a worn sprocket and achieving a quieter and smoother transmission without heavy modifications. The rubber is formulated to resist detachment during road use and long stages, while the steel ensures mechanical strength and durability. Compatible with several modern 660 cc models (e.g. Aprilia Tuono 660 and Tuareg 660 Rally), please check compatibility with your machine before installation.
