EBC OSX4171 OSX Series Oversize Front Brake Rotor Kit with Bracket

The EBC OSX4171 is part of EBC's industry-leading OSX Series oversize brake rotor kit lineup, purpose-built for motocross and off-road riders seeking a significant upgrade in stopping power. This kit replaces your stock solid rotor with a larger-diameter, fully floating rotor and includes a precision-machined relocation bracket to retain your standard caliper — no other modifications required.

Key Features:

• Fully floating rotor design resists warping and handles heat and heavy braking loads better than stock solid rotors
• German mill-rolled stainless steel rotor blade and center hub for superior strength and corrosion resistance
• British laser-profiled and CNC-punched contoured rotor blade for maximum weight reduction and self-cleaning performance
• Six-button stainless steel drive button system for secure, rattle-free floating action
• Billet aluminum caliper relocation bracket designed by MX expert Ted Devol in California — precisely engineered for a perfect fit
• Matte carbon fiber-look center hub finish for a premium appearance
• Improves braking power by up to 30% over stock disc size
• Retains your standard OEM caliper, cables, and hydraulics — no other changes necessary
• Quick and easy installation in minutes with basic hand tools

The EBC OSX4171 oversize rotor kit is the go-to upgrade for riders who demand more control and modulation from their braking system without the complexity of a full brake system overhaul. Made in the United Kingdom to EBC's exacting quality standards, this kit delivers race-proven performance for both competitive and recreational off-road use.
