The EK/JT 520MRD7 13/48 chain kit is a set designed for motocross use: a 520MRD7 chain combined with a 13-tooth sprocket and a 48-tooth mud-profiled rear sprocket. Designed to reduce friction, this kit provides mechanical durability suited for off-road conditions while facilitating mud evacuation thanks to the specific sprocket design.
Suitable for muddy conditions and terrain demands, this kit is aimed at motocross riders looking for a robust setup and optimized transmission performance. Compatible notably with Kawasaki KX 250 F (2004-2005 models), it is a serious option for replacing chains and sprockets to restore a responsive and clean rear end for off-road use.
