RFX Race Fixed Petal Brake Disc — Manufacturer Ref: FXBD4050555BK. Designed for the motocross world, this RFX petal disc combines materials and machining to meet the demands of off-road riding. Its laser-cut stainless steel ensures tight tolerances and good resistance to external aggressions, while the heat treatment limits excessive wear on the pads.
The unworn face receives a Comaxit coating that is resistant to heat and corrosion to preserve its appearance and durability. The friction surface is precisely ground (0.01 mm) to ensure uniform flatness when in contact with the pads.
This disc is suitable for motocross and cross practices where reliability and resistance to mud, debris, and thermal cycles are essential. Ideal as a replacement for several YAMAHA YZ models (e.g., YZ 125, YZ 250, YZ 250X), it will be perfect for riders looking for a robust and easy-to-install part.
