4DP Yamaha TZ250 discs front BSE gold cast iron 280 mm

4DP Yamaha TZ250 front brake discs. These are quality discs by BSE, with gold inner rotor and cast iron 280 mm disc. They are rusty, as you'd expect with cast iron, so need a clean up. Will also fit TZR250 3XV and R1-Z models. Cast iron rotors offer many benefits: *Durability: Cast iron is a robust material, can withstand significant heat and stress during braking, making it a reliable choice for high-performance applications like racing. *Good Heat Dissipation: Cast iron has good heat dissipation properties, which helps prevent brake fade during intense driving conditions. *High Friction Coefficient: Cast iron offers a reasonably high friction coefficient, ensuring effective stopping power and consistent brake feel. *Easily Machined: Cast iron is relatively easy to machine, allowing for the creation of complex rotor designs like vented and slotted rotors. * High Carbon Content: High carbon content can help reduce noise and improve heat dissipation.
