The EK/PBR 520MRD7 chain features a construction that minimizes friction while maintaining good tensile and abrasion resistance — essential qualities for tackling mud, jumps, and the typical accelerations of motocross. The aluminum sprocket lightens the rolling train and contributes to a lively feel during acceleration. The golden aesthetic adds a polished and race-ready look to your machine.
Compatible with many 250 SX-F models (e.g., KTM 2011–2012) and other enduro/cross bikes equipped with 520, this kit is aimed at riders looking for a reliable, easy-to-maintain transmission suited to the rigors of the terrain.
