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:
