Specifically designed for motocross use, the EK/PBR 520M3 13/51 chain kit combines a high-end chain and an ultra-light aluminum sprocket to minimize unsprung weight while maintaining durability against the demands of off-road riding. The gold finish adds a racing touch and provides visible corrosion protection.

The construction of the EK/PBR chain emphasizes reduced friction and good resistance to abrasion and tension—essential characteristics for endurance outings and competition. The ultra-light aluminum sprocket decreases rotational inertia for a more responsive behavior at high RPMs, while still maintaining a design suited to the stresses of the terrain.
Compatible with motocross machines and ready to be mounted on trails and enduro/cross bikes such as the HONDA CR 125 R (JE01) 2002, this kit is aimed at riders looking for a performance-oriented and lightweight chain/sprocket set. Always check the number of teeth and pitch before installation to ensure compatibility with your motorcycle.
