EK/PBR 520MRD7 14/51 Chain Kit - Standard Sprocket
Designed for the motocross world, this EK CHAIN kit combines durability and meticulous finishing for demanding riders. The 520MRD7 chain, in gold/gold color, aims to minimize friction while providing good resistance to traction and abrasion, suitable for the rigors of tracks and competitive conditions.
Ideal for Cross machines, this kit is particularly compatible with KTM 250 SX-F (2020, 2021, 2022). Installation and adjustment should be carried out according to manufacturer specifications and regularly checked: chain tension, condition of the teeth, and lubrication. To maintain a responsive and safe transmission on the track, prioritize regular maintenance and replace the sprocket/crown/chain set in case of visible wear.
