EBC Contour X Disc MD4154XC

Floating MC rotors feature EBC Brakes 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. As the design of Motorcycles progressed over the last 10 years with machines getting lighter, more powerful and faster the demand on Motorcycle brakes has increased. Great technical forward movements such as 4 and 6 piston calipers and more recently the radial caliper have helped stop motorcycles faster but there has been, until now little progress made on brake rotors. There have been attempts to reduce weight on rotors, usually by drilling more holes in the rotor blade but always the OEM builders have used the boring “Round Style” rivet or drive button technology.

This outdated method of building rotors has now been consigned to the history books as EBC Brakes proudly announces the arrival of a new and patented design of drive button known as the SD System. SD stands for Square Drive which describes the button designs used in the new EBC X and XC rotors.
