RFX Race Wave Front Brake Rotor  FXBD2020055BK - Kawasaki KX80 / KX85 1993-2026

Product Description

The RFX FXBD2020055BK Race Wave Front Brake Rotor delivers high-grade stopping performance engineered specifically for Kawasaki KX80 and KX85 minicycles. Precision laser cut from high-grade stainless steel, this front rotor is heat treated to resist mechanical grooving and wear under intense motocross braking. The CAD-engineered contour reduces unsprung rotational mass at the front wheel hub, directly improving steering agility, front-end feel, and suspension responsiveness on rough track sections.

Thermal stability is handled through precision-machined ventilation holes and an aggressive wave profile that work together to channel cooling air across the rotor face, preventing brake fade during long motos. The wave outer profile continuously scrapes debris from the brake pad faces to preserve uniform friction contact in heavy mud and sand. Finished with a protective Comaxit coating on non-contact surfaces, this rotor provides lasting resistance against moisture, corrosion, and trail grit.

Top Features: RFX Race Wave Front Brake Rotor

• Laser cut from high-grade stainless steel for exact hub fitment and dimensional accuracy.
• Heat treated construction withstands excessive wear from aggressive brake pad friction.
• CAD-designed profile reduces unsprung rotational weight to improve front-end handling.
• Wave profile design continuously cleans the brake pad surface of mud and track debris.
• Precision cut vented holes dissipate heat rapidly to reduce lever fade under heavy braking.
• Comaxit surface coating shields non-wear surfaces against corrosion and environmental wear.

Frequently Asked Questions

Q: What material is used to construct this RFX brake rotor?
A: The rotor is laser cut from high-grade stainless steel and heat treated to resist surface wear and maintain integrity under elevated brake temperatures.

Q: How does the wave design improve front brake performance?
A: The wave profile optimizes heat dissipation, sheds unsprung rotational weight, and clears away mud and debris from the brake pads to maintain consistent stopping grip.

Q: Is this rotor designed for the front or rear wheel?
A: This FXBD2020055BK rotor is engineered specifically for front wheel fitment on the listed Kawasaki KX80 and KX85 models.

Expert Pro-Tip: When installing a fresh front rotor on a minicycle hub, thoroughly degrease the wheel hub mounting surface using contact cleaner to ensure the disc sits completely flat. Always clean the mounting bolt threads, apply a drop of blue medium-strength threadlocker to each bolt, and torque them in a cross-pattern to factory service manual specifications. Pair the new disc with a fresh set of brake pads, and complete 5 to 10 progressive, rolling stops before taking the bike to race pace so the pad compound beds into the stainless steel without heat glazing.
