EK/PBR 520MRD7 Chain Kit 13/48 - Standard Sprocket
Brand: EK CHAIN — Chain kit dedicated to motocross, delivered with a 13-tooth sprocket and a 48-tooth rear sprocket. Designed for the demanding conditions of off-road riding, this kit features a robust 520 chain and a standard steel rear sprocket for reliable transmission on the track.
The Gold/Gold finish adds a visual touch and provides protection against superficial corrosion. The kit includes 114 links (pitch 520) and has a reference weight of 1.47 kg for 100 links, useful for estimating the impact on unsprung mass.
Practical compatibility: designed for motocross bikes — particularly suitable for KTM 450 SX‑F (2018‑2019) and Herlings replicas. Before installation, check the number of links and adjust the length if necessary (cutting and riveting). To preserve longevity, adhere to the tension and lubrication intervals recommended by the manufacturer.
