Cast Iron Rust Proof Motorcycle Front Disc Brake Rotor High Strength

This is the front brake disc suitable for the CG125 model, a key component of the vehicle's braking system; the main material is high-strength cast iron (some upgraded versions use stainless steel), with rust-proof treatment on the surface, balancing wear resistance and deformation resistance; the silver outer ring is the braking friction surface, with long strip-shaped cooling holes on the surface to quickly dissipate heat generated during braking, preventing 'brake fade' (reduced braking performance); the black middle area is designed with cut-outs to reduce weight and enhance structural rigidity, while aiding heat dissipation; the inner disc has reserved mounting holes for connection with the wheel hub, compatible with the front axle specifications of the CG125. Working with the brake caliper and brake pads, it converts the vehicle's kinetic energy into heat through friction to decelerate or stop, making it one of the core components for riding safety. Good heat dissipation: the design of the cooling holes effectively reduces brake temperature and improves stability during continuous braking; high braking efficiency: the friction surface area and material match the power requirements of a 125cc model, providing responsive braking; strong durability: cast iron material resists wear, with a normal lifespan of 10,000–20,000 kilometres depending on riding habits.
