EBC MD870XC XC Series Contoured Floating Motorcycle Brake Rotor with S-Drive System

The EBC MD870XC is a premium fully floating motorcycle brake rotor featuring a contoured lighter weight profile designed for enhanced performance and reduced unsprung weight. This high-performance rotor is part of EBC's ProLite XC series, engineered for motorcycles that demand superior stopping power without unnecessary bulk.

Patented S-Drive Button System:

EBC's unique and patented S-Drive button system features square sided rivets captured in square drive pockets on the rotor and hub which allow the outer rotor blade to expand and contract freely under the heat of braking without suffering rivet lock. This innovative design completely eliminates rotor warping and brake vibration issues common with traditional circular button designs.

Key Features:

• Contoured profile reduces weight by 7.5% without reducing actual cooling mass
• German mill rolled heat treated stainless steel rotor blade for exceptional durability
• Vertical scraper slot system removes dirt, dust and debris quickly from braking area
• Unique fully overlapping vent hole pattern reduces weight, cleans disc blade and helps deglaze pads
• Ultra lightweight ductile alloy centre hub
• Mill hard stainless steel high friction rotor blades for maximum brake effect

Manufactured with precision in the United Kingdom to exacting tolerances, this rotor delivers direct OEM fitment and is suitable for street riding, track days, or competitive racing applications. The XC contoured design provides optimal balance between weight reduction and thermal management for consistent, fade-free braking performance.
