front sprockets YAMAHA 250 YZ 80-81

The sprockets are made of hardened 18NCD5 steel using CNC machines and washed in a special oil which makes them brighter and removes rust corrosion.

The innovative and exclusive Dicronite Dry Lube DL-5 treatment increases the smoothness and, consequently, the transfer of engine power and the life of the components.

The competitions are part of the DNA of PBR, which produces gears and accessories for all types of motorcycles, and distributes the prestigious Japanese EK chains. The 360 ​​° presence of PBR in racing has always been an indispensable test bench for new materials, processes and treatments that then improve the production dedicated to the series and after-market. For this reason PBR has been supporting the LCR Honda team for several years in Moto GP.

The PBR has also created a new line of racing sprockets in the 520 wheelbase version equipped with lightening holes, much lighter than the original ones but still with high qualities of strength and durability.
