EK/PBR 520M3 Chain Kit 14/52 - ultra-light sprocket from the EK CHAIN brand, designed for motocross use. This kit includes a 520 chain in gold finish and an ultra-light aluminum sprocket, engineered to reduce rotational mass without compromising abrasion resistance and traction during off-road rides.
Ideal for riders looking for a robust and lightweight transmission set, it combines a reliable 520 pitch with an aluminum sprocket for a noticeable weight reduction at the rear wheel. The chain features 116 links and a relative wear index of 450 (reference for 100 links), providing a good balance between longevity and performance on demanding terrains.
