RFX Race Fixed Petal Brake Disc (manufacturer part number FXBD5070555BK) — a disc designed for the motocross world, combining precise machining and durable materials for a reliable replacement on small competition engines.
Laser cut from high-quality stainless steel and heat-treated, this disc features a ground surface to ±0.01 mm and a Comaxit coating on the unworn faces to limit corrosion. The wavy petal profile and ventilation openings ensure effective debris clearance and heat dissipation, while CAD machining reduces unsprung weight to maintain the bike's handling.
Ideal for riders looking for a robust and lightweight replacement disc for their 65 cc — specifically KTM 65 SX (2024), HUSQVARNA TC 65 (2024), and GAS GAS MC 65 (2024). Direct fit as an OEM replacement according to compatible references.
