Minitwins race bikes and race bike parts and tuning

James Holland racing at Brands HatchFor the last two years Minitwin racing has proved to be an enormous success, bringing low-cost competitive motorcycle sport to many.  Originally run under the auspices of BEMSEE, for 2004 North Gloucester also ran their own equivalent.

For 2005 the series will also run at MRO rounds and may even run with the Supersport 400 class at the Andreas Racing Club on the Isle of Man

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 organisers websites for full details of the 2005 regulations.  

We are pleased to be at the forefront of developing and building cost-effective new machines for this series.  The performance of our bikes has never been in doubt, culminating in 2004 in our own sponsored rider, Nigel Reed, winning the North Gloucester Road Racing Minitwins championship, 47 points clear of his nearest rival.  Read their own report here.
