An affordable route into competitive motorcycle racing

Over the last few years Mini Twin racing has proved to be an enormous success, making low-cost competitive motorcycle sport accessible to many more people. Popular with spectators too, the 2005 season was televised on the British Eurosport satellite & cable channel.

Participating bikes must be four-stroke twins under 650cc. Limited modifications are allowed, such as a race pipe, fuelling changes, suspension tweaks 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 site includes a useful guide for those wishing to know more about what's involved in getting into racing; and the British Motorcycle Racing Club (www.bemsee.co.uk), whose site also offers a comprehensive source of information about the sport.

 

JHS are proud to be at the forefront of developing and building cost-effective new machines for this series. Our bikes are supplied fully regulation-compliant and ready to race. The JHS Racing MiniTwin Our racing machines are most commonly based on a heavily modified Suzuki SV650 or SV1000 V-twin.

The Suzuki SV is a popular platform because of its low initial purchase cost, beautifully balanced frame and its superb V-twin engine, regarded as one of Japan's finest. Beginning with a brand new bike, we strip and upgrade the engine to boost power, and race-specify all key components such as brakes and front and rear suspension. Typical specification includes: :: A choice of DOT race tyres (Dunlop, Metzeler, Pirelli). :: Nitron fully adjustable race spec rear shock. :: Hel stainless steel brake line kit F/R. :: 45t alloy talon rear sprocket + 44t standard rear. :: CNC machined rear set kit. :: Progressive or Ohlins front fork spring / spacer kit. :: M4 alloy high sport slip/on pipe or titanium end can. :: Race fairing/seat kit with Dzus fasteners (finished in    white primer ready for painting). :: We can offer painting of the body work to match fuel    tank colour at an extra cost of £300.00 :: Paddock stand bobbins. :: Chain protector. :: Dyno set up with power output printout.

See our Bikes for Sale page for more information about the motorcycles currently available. The performance of our bikes has never been in doubt, clearly demonstrated in 2004 when our own sponsored rider, Nigel Reed, won the North Gloucester Road Racing Minitwins championship, 47 points clear of his nearest rival.
