EBC MD669X Brake X Series Contoured Motorcycle Disc Rotor

The EBC MD669X Brake X Series rotor delivers enhanced stopping power through advanced materials and innovative design. Engineered for high-performance motorcycles, this contoured disc rotor features a special blend of high-friction billet steel that provides up to 10 percent improvement in braking friction over standard heat-treated stainless steel rotors.

Key Features:

• High-friction billet steel rotor blade construction for superior stopping power
• Forged aluminum center hub reduces weight by 5-10 percent compared to stock rotors
• SD-System square-sided floating buttons allow unrestricted thermal expansion and contraction
• Contoured design enhances brake pad contact and heat dissipation
• Universal left or right side application for installation flexibility
• Floating rotor design maintains optimal performance under varying speeds and loads
• Increased durability through advanced metallurgy and engineering

The SD-System mounting design uses square-sided buttons that permit the rotor to expand inwards and outwards without restraint, ensuring perfect functionality at any speed or load while extending rotor life. The lightweight forged aluminum hub and contoured rotor blade work together to reduce unsprung weight while improving brake feel and response. Sold individually.
