Great service, can’t thank you enough. When every other parts supplier let me down these guys saved my bacon. Wouldn’t hesitate to recommend them. Thanks again.

MC Brake Rotors

X and XC Floating MC rotors are the lightest rotors you can buy, they will eliminate all your vibration problems and last longer than conventional rotors using round button technology. Both designs further reduce weight by using only six drive buttons.

This further reduces the unit weight by up to 300 grammes.

  • X rotors feature full circle, circular rotor blades
  • XC rotors feature a contoured lighter weight profile.

X Series Floating Rotor

Both Floating MC rotors feature mill hard stainless steel high friction rotor blades for maximum brake effect and are direct size for size replacements for OEM rotors. Both designs are also true fully floating units, offering more inside to outside float tolerance than any other rotor on the planet.

Do not confuse floating rotors with rotors that feature loose rotors blades or buttons. You should not be able to move either the buttons or rotor blades from side to side, if you can, it is highly likely that pad “Knock Back” will occur and you will end up with spongy brakes. Float means outside to inside heat expansion ability. That is what EBC X and XC rotors deliver and no other rotor can.

XC Series Floating Rotor

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This outdated method of building rotors has now been consigned to the history books as EBC Brakes proudly announces the arrival of a new and patented design of drive button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.

Technical Information

floating rotors

X Series - Fully floating front rotor

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 Brakes 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 Brakes patented S-Drive system.

What is S-Drive? EBC Brakes square sided drive button system completely eliminates the chance of rotor warping, extends rotor life and improves consistency of brake effect.

XC Series - Fully Floating Front Disc/Rotor

EBC ProLite XC contour rotors are the toughest and yet the lightest sport and race brake rotors you can put on your bikes for many reasons and here is why these are best.

  • Contoured profile reduces weight by 7.5% without reducing actual “cooling mass” of disc.
  • New German mill rolled heat treated stainless steel rotor blade.
  • 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.
  • New Patented Stainless Steel SD (square drive) button drive system, prevent warping and vibration totally system – click here for full tech info.
6) Ultra lightweight ductile alloy centre hub.
  • Use of SD system allows less drive buttons, in the case of EBC we are down to six buttons
  • Full stainless components, no rusty parts and that’s guaranteed.

For over 30 years EBC has been the number one in brake pads and these new XC Contour rotors stake the EBC claim to the rotor market leadership. These rotors can be used on the street, track-days or Road Racing and hundreds of privateer teams all over the world race these.
