Now firmly established as one of the country's leading motorcycle performance tuning specialists, JHS was established in 1996 by James Holland. James has worked within the motorcycle industry and been closely associated with the club and supersport racing scene for many years.
The majority of our work undertaken today consists of road and track bikes. However, our engineering and tuning skills originated from our hand-crafted, bespoke classic motocross machines. These bikes were successfully raced in the 1990s by both James and the multi-European and World Champion Trials rider 'Magical Mick' Andrews. Today, we race our JHS race bikes at New Era, MRO and NG Road Racing, with numerous wins achieved. Our most recent team riders have been Nigel Reed, Craig Polden, Andrew 'Doon' Marsden and of course James himself.
