EK/PBR 520MRD7 Chain Kit 13/51 - Ultra-Light Sprocket
Specifically designed for motocross, this EK CHAIN kit combines lightness and robustness. The aluminum "ultra-light" sprocket reduces unsprung mass for a more responsive rear wheel behavior, while the chain handles the traction and abrasion inherent to demanding terrains.

This kit is aimed at riders looking for a high-performance transmission for enduro and motocross: quick starts, acceleration, and endurance on soft ground. The golden finish also gives a polished look to the rear of the motorcycle. Compatible with many motocross machines, it is particularly suitable for models like the HONDA CR 125 R (JE01) – 1983 (125 cc) according to mechanical compatibilities.
Usage tip: check the torque of the sprocket bolts and regularly retighten the chain after the first hours of use to ensure optimal longevity on hard and muddy terrain.
