Mad Biker Designs originally got its name by designing products for the off road market.  Whether it be off road or road bikes we always had a keen interest in two stroke motorcycles and some of our personal projects were building two stroke specials for the road. 

Simple jobs that should be straight forward we struggled to get done through either bad service or workmanship, making building a bike more complicated then it need be. 

In 2012 the decision was made to start Mad Biker Designs. Primarily focusing on the Yamaha RD to make it easier for people to build motorcycles to their specs, and inject some life into the previously stale scene that consumers were faced with . We are the original people to Import Wicked motorsport parts into the UK and still continue to lead the way in the development of  RD based big bore kits. Our own bike was the 1st one in the UK to break the 100hp barrier from a 421cc engine. 

The success of Mad Biker has led us to move into stocking some of the finest names in motorcycling today. Ranging from Brembo, Nitron, OZ, AFAM, Nova and Racebolts to name a few.
