Designed by PBR, this front sprocket is aimed at riders looking for a robust replacement part for a 630 chain transmission. Inherited from the experience gained in competition, it is machined from an 18NCD5 steel alloy, a material recognized for its mechanical strength and abrasion resistance. Its finish minimizes wear points and contributes to a consistent lifespan of the transmission.

Suitable for classic roadsters and customs, this sprocket can be installed as a replacement on many machines (e.g. SUZUKI GSX 1100 EF, KAWASAKI Z 750 GP KZ750R, SUZUKI GSX 1100 E). When replacing, check the condition of the chain and the rear sprocket to ensure uniform tooth engagement and avoid premature wear. Professional installation is recommended if you are not equipped.

A solid and straightforward part, this PBR sprocket is a reliable option to restore the front transmission and regain a rolling geometry that meets manufacturer specifications.
