AFAM 520XRR3 14/50 reinforced chain kit with Ultra-Light sprocket, designed to withstand the high stresses of off-road riding while reducing rotating mass for improved responsiveness.
AFAM offers a 520-pitch chain kit for the KTM 380 SX 380cc, consisting of a reinforced XRR3 chain with X-Ring seals, a 14-tooth steel sprocket, and a 50-tooth Ultra-Light aluminum rear sprocket. The chain’s reinforced design allows it to withstand the load variations and repeated accelerations typical of intensive off-road use. The X-Ring seals help maintain lubrication at the chain links and reduce internal friction, promoting more gradual wear. The aluminum sprocket reduces rotating mass compared to a steel sprocket, which helps the rear wheel respond more quickly during acceleration and changes in pace. The steel sprocket ensures precise engagement with the chain and effectively withstands the forces transmitted by the engine. This assembly thus offers a complete solution for replacing a heavily used drivetrain by combining durability, light weight, and off-road performance.
