There are three types of brake pad used on modern motorcycles and these fall into three groups, Organic, Semi-metallic or Sintered.

Semi-metallic pads are blended with up to 30 or 50% cheap steel fiber, Organic pads are manufactured with man-made fibers such as Kevlar or Twaron, bonded together with a petro-chemical resin; Sintered metal pads are copper alloy fused together under heat and pressure. EBC Brakes makes only Organic and Sintered brake pads as they do not believe that the steel fiber technology is suitable for motorcycle brakes for numerous reasons. Organic pads have attracted many enthusiasts because of the way they work. They are inherently easier on rotors and have a brake “feel” preferred by many riders. EBC make only two formulations of organic pads for motorcycles which are described as follows:

Street Sport DMX compound.
Made with DuPont Kevlar fiber base this material has been sold in over 18 million sets alone since adopted. It is surely one of the best selling motorcycle brake materials ever made and has passed every known standard test time and time again. It has been rated by top German consumer magazine Motorrad as a compound that outperformed all compared organic pads in friction level. DMX compound is TUV (German national quality standards authority) tested and approved and is the first ever material to pass the European ECE R90 brake safety test where it was tested alongside sintered metal pads. With a GG rated friction rating, technically this material has a lower rating for brake power over sintered pads but on the machine, which is where it counts, this materials impresses. Having passed the ECE R90 test on motorcycles designed for sintered pads there is no doubt that this materials CAN BE USED TO REPLACE sintered pads on most motorcycles with safety. Enduro Grade TT or X pads
This is the EBC pad compound used for larger and heavier Enduro or what is sometimes called Paris-Dakar type or dual purpose machines. The material is carbon based with Kevlar fibers and as a softer pad is less aggressive on rotors and runs cooler than sintered metal. It will last longer than its stable mate the DMX formula in dual purpose use which is why EBC make this alternate grade for Enduro type motorcycles. Again the EBC philosophy is to give the customer a choice and offer a range of pad compounds ideal for each market segment.
