material: The front brake rotor is made from strength metal material, offering resistance to oxidation, erosion and wear. It is rustproof and designed for longterm stable use. Compatible models: Replacement for SSR, Apollo, Taotao, Coolster, SDG, and dirt pit bike motorcycles. Ideal replacement: Replaces old or damaged original brake disc rotor, restoring original braking efficiency and greatly improving driving stability. Improved brake performance: Delivers braking efficiency, reduces driving noise, and enhances driving safety and comfort. Key benefits Restores braking performance when the rotor is worn or damaged Simple replacement for the original rotor, supporting compatibility and easy installation Improves braking control and stability in offroad riding and varying terrain Reduces noise during braking and enhances overall riding comfort Use scenarios After extended offroad riding or racing on SSR, Apollo, Taotao, Coolster, or SDG dirt pit bikes, the rotor to restore braking efficiency and control Ahead of track days or practice sessions for dirt pit bikes, upgrade the rotor to improve braking performance and rider safety As part of routine safety maintenance for dirt pit bikes used on trails, to maintain braking reliability and comfort during riding
