EBC OE Front left/right Rotors (#MD621X)

X Series - Fully floating front rotor

Ultra lightweight new EBC X series floating front rotors for sportbikes and road racers are now available from EBC Dealers across the USA although as a new line many dealers will have to special order these for you (takes 2-3 days).

The new rotors feature EBC's unique and patented S-Drive button system which 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.

Rivet lock is the term used when rotors heat up under heavy braking and the rotor blade contacts the (normally circular) rivets that separate the inner rotor hub and the outer rotor blade. The new EBC system completely eliminates this problem area which causes 100% of the failures of rotors suffering from distortion and brake vibration.

These rotors are equipped with the NEW EBC PATENTED S-DRIVE SYSTEM
