Product details :

Features

EK/PBR 520MRD7 13/51 Chain Kit — a transmission set designed for motocross, combining lightweight construction with durability to withstand the demands of challenging terrains. The ultra-light anodized aluminum sprocket reduces unsprung weight while providing a wear-resistant finish. The chain and sprocket are ready to handle the specific accelerations and RPM changes associated with off-road motorcycles.

Color: Gold/Gold
Pitch: 520
Configuration: 13/51 (13-tooth sprocket / 51-tooth crown)
Number of links: 114
Crown material: Hard anodized aluminum (ultra-light)
Weight: 1.47 kg for 100 links
Relative lifespan (for 100 links): 450

Designed for motocross riders, this kit prioritizes friction reduction and good abrasion resistance. The gold aesthetic adds a visible racing touch, while the lightweight crown enhances rear wheel responsiveness without compromising the strength necessary for competition or intensive off-road outings.

Compatible with several 125cc motocross models: including SHERCO 125 SE-R FACTORY (2022) and SHERCO 125 SC (2019-2020). Before installation, check the pitch and the required number of teeth for your model to ensure a perfect fit.
