An affordable route into competitive motorcycle racing

JHS Racing create bespoke, hand-built racing motorcycles that equip you with a highly-competitive but affordable foundation for participating in both club and national-level road racing.

With our successful and distinguished record of competing at many levels, including the British Supersport series, you can benefit from the race-proven knowledge and experience we bring to bear on every machine that we build.

Our most commonly-used platform for race bike development is Suzuki's SV650, providing both a beautifully balanced frame, and a tough and enduring engine well-suited to a range of tuning modifications. We also have extensive experience with race-preparing the Triumph Daytona 675.

Our racing motorcycles are supplied fully regulation-compliant and ready to race. Typical specifications of our built-to-order racing machines are listed below:

Mini-Twins Series

In recent years the Mini Twin Racing Series has proved to be an enormous success, making low-cost competitive motorcycle sport accessible to many more people. Popular with spectators too, the series has in the past even been televised on the British Eurosport channel.

Participating bikes must be four-stroke twins under 650cc. Certain modifications are permitted, such as a race pipe, fuelling changes, suspension units and race fairings. Please refer to the organizers web sites for full details of the current regulations.

Key organizers for the Mini-Twins series are:

North Gloucester Road Racing (www.ngroadracing.org) - whose web site includes a useful guide for those wishing to know more about what's involved in getting into racing;

the British Motorcycle Racing Club (www.bemsee.co.uk), whose site also offers a comprehensive source of information about the sport.
