RFX Race Fixed Petal Brake Disc (Manufacturer part number: FXBD2070555BK)
Designed for motocross use, the RFX Race Series disc offers a competition-oriented construction: laser-cut from high-quality stainless steel, heat-treated, and surface-ground to 0.01 mm precision. Its fixed petal profile and CAD design minimize unsprung weight while ensuring consistent lever feel. The Comaxit coating on the unworn surfaces provides corrosion protection without affecting the contact area of the pads.
This disc is aimed at riders who want robust and precise equipment for their outings in varied terrain: the wavy profile and optimally placed holes enhance pad cleaning and thermal dissipation, which is crucial in motocross where mud and dust are prevalent.
