The RFX Race fixed petal brake disc (manufacturer part number FXBD4030055BK) provides a robust and lightweight solution for motocross. Laser-cut from high-quality stainless steel and heat-treated, it aims to offer controlled wear of the pads and good longevity. Its black Comaxit finish on the non-working faces limits corrosion and gives a refined look to your fork.
Designed for responsive braking, the disc is surface-ground with tight tolerances to promote consistent pad engagement and minimize vibrations. The petal profile and cutouts ensure effective cleaning of the pads and heat dissipation during intense off-road sessions.
Main features:
Suitable as a replacement part for many motocross models — including YAMAHA YZ 250 (CG08), YZ 125 (CE05), and YZ 400 F (CH03) — check the mounting diagram and your references before installation. For riders seeking rigidity, pad cleaning, and racing style on their front disc, this RFX model remains a serious option.
