EK/PBR 520M3 13/50 Chain Kit - Ultra-Light Sprocket: a set designed for motocross riders seeking a reliable and lightweight transmission. This kit combines a high-performance 520M3 chain with an ultra-light aluminum rear sprocket, engineered to withstand the demands of challenging terrains and competitive use.
The EK CHAIN chain/sprocket combination prioritizes friction reduction and excellent resistance to tensile stress and abrasion—essential qualities for enduro outings and track sessions. The ultra-light aluminum sprocket reduces the weight of the rear wheel to enhance maneuverability without compromising the mechanical integrity expected from intensive use.
Common compatibilities: KTM 450 XC-F (2020, 2021, 2022) and other 450 motocross machines equipped with a 520 pitch. For secure installation, check the fit, tension, and condition of the rivets during setup.
