AFAM 520MX6 14/51 Reinforced Chain Kit - Ultra-Light Sprocket for GAS GAS, HUSQVARNA FC, KTM SXF, XCF, 250, and 350 models from

AFAM offers this 520MX6 Racing chain kit for the GAS GAS MCF 250 cc, GAS GAS EXF 350 cc, HUSQVARNA FC 250 cc, HUSQVARNA FC 350 cc, HUSQVARNA FC 250 FACTORY EDITION cc, KTM SXF 250 cc, KTM XCF 350 cc, KTM XCF 250 cc, and KTM SXF 350 cc, featuring a 118-link seamless chain, a standard 14-tooth sprocket, and a 51-tooth Ultra-Light aluminum chainring. The MX6 chain is specifically designed for motocross, and its reinforced construction withstands the heavy stresses imposed by repeated acceleration, landings, and quick restarts. The aluminum sprocket reduces the weight of the drivetrain compared to a steel sprocket, thereby limiting the inertia of the rotating components. With a gear ratio of 14/51 (3.64), this configuration prioritizes traction and acceleration while maintaining a gear ratio suited to the pace of the race. The set thus combines a reinforced Racing chain and an Ultra-Light chainring to achieve a good balance between mechanical strength and lightness.
