RFX Race Fixed Petal Brake Disc (FXBD5040055BK)

Designed for competition and demanding riders, the RFX Race fixed petal disc combines precision manufacturing and durable materials for the motocross environment. Laser-cut from high-quality stainless steel, it undergoes a heat treatment to minimize brake pad wear and maintain stable geometry under heavy load. The non-working faces feature a Comaxit coating that is resistant to heat and corrosion, while the contact surface is ground to ±0.01 mm for consistent braking engagement.

The wavy petal design and holes (Ø 6.5 mm) promote brake pad cleaning and thermal dissipation, reducing the risks of discoloration and premature overheating during off-road outings. Designed using CAD, its profile helps limit unsprung mass without compromising rigidity.

Technical specifications:

• Outer diameter: 220 mm
• Inner diameter / bore: 95.05 mm
• Thickness: 3 mm
• Hole diameter: Ø 6.5 mm
• Color: black (Comaxit coating on non-working faces)
