Kevin Thurston Transmissions


Kevin (KRT) has been designing, developing and producing high quality modifications for Velocettes for over 17 years.

KRT Racing started in 1995 and as a design engineer working on jet engine thrust reversers, tanks and submarines, Kevin became more interested in the technical development of Velocettes. He started producing parts to reduce weight and improve performance for his own bikes.

This became more than just a hobby, producing performance parts for Velocettes, and on 1st September 2009, Kevin started up in business as a Sole Trader.

KTT Services’ mission is to get more Velocettes competitive on the race track and to improve road bike performance and reliability.
