Made with Dupont Kevlar fibre base this material have sold 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 tested. DMX compound is TUV 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 past the ECE R 90 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.
