EK CHAIN 520MRD7 13/43 Chain Kit - Standard Sprocket
Designed for the demanding uses of off-road and motocross, this EK chain kit offers a combination of durability and meticulous finish. The 520MRD7 chain in gold finish minimizes friction while providing good resistance to tension and abrasion — qualities sought after both on the track and during off-road outings. The standard steel sprocket accompanies the 13-tooth pinion for a simple and reliable installation.
Ideal for those seeking a robust installation and a polished look, this kit requires regular maintenance: checking tension, cleaning, and lubrication suitable for off-road use to preserve the links and sprocket. Replace the pinion and sprocket at the same time as the chain to maintain a clean transmission and optimal acceleration response.
