AFAM ' 520XSR 14/48 Super-Reinforced Chain Kit - Ultra-Light Mud-Resistant Sprocket for KTM SX, EXC 520, and 525 Models from 200

AFAM offers a 520-pitch chain kit for the KTM 525 SX RACING 525cc, KTM 520 EXC RACING 520cc, KTM 520 EXC RACING SIX DAYS 520cc, consisting of a super-reinforced XSR chain with X-Ring seals, a 14-tooth steel sprocket, and a 48-tooth Ultra-Light aluminum rear sprocket with a mud-resistant design. The XSR chain is designed to withstand high transmission loads and repeated stress, while its X-Ring seals help maintain lubrication at the joints and minimize internal friction. The aluminum sprocket reduces rotating mass compared to a conventional steel sprocket, resulting in a lighter rear drivetrain and more responsive handling. Its mud-resistant design facilitates the removal of debris that can accumulate around the drivetrain when riding on wet or muddy terrain. The 14/48 configuration offers a gear ratio suited to compatible motorcycles, striking a balance between acceleration and top-end speed based on the stock gear ratio. Finally, the steel sprocket ensures precise engagement with the chain and withstands the high forces transmitted by the engine.
