EK/JT 520MRD7 Chain Kit 14/48 - Ultra-light Sprocket
This EK CHAIN kit is designed for off-road riders seeking a lightweight and reliable transmission for motocross. It combines a robust 520 chain with an ultra-light aluminum sprocket, reducing unsprung mass for a more responsive engine behavior during jumps and accelerations. Engineered to withstand the demands of track and trail use, it limits abrasive wear while maintaining good tensile strength.
Simple installation and maintenance: check tension, lubrication, and wear of the links after muddy rides to preserve longevity. Commonly fitted on: KAWASAKI KX 250 F (2004 - 250 cc). This kit is aimed at demanding riders who want a transmission suited to the challenges of motocross, balancing delivered power and reduced rotating mass.
