DID 520ERT3 - Non Sealed Chain

The 520ERT3 is a high-performance drive chain engineered specifically for the demands of professional motocross and supercross racing. Its non-sealed design prioritises minimum friction and weight reduction for maximum power transfer to the rear wheel.

• Incorporates SDH pin technology which creates a hard chromium carbide outer layer for superior wear resistance.
• Features a high tensile strength rating to handle the explosive torque of modern race engines.
• Gold plating on the outer plates provides a factory look while resisting surface corrosion.
• Optimised plate thickness reduces rotating mass, improving throttle response and suspension performance.
