Supersport

There has been widespread speculation that MA was planning to alter the rules to bring the Supersport class into line with the FIM rules. However, after surveying a considerable number of Supersport privateers, it became apparent that any such moves would be counterproductive to the future success of this class. The purpose of the class is to provide production-based racing at a reasonable cost to competitors. It was decided against introducing any rules that would add cost.

As a result, there is no major change to the engine specification. MA will not be following the FIM engine regulations.

There is a slight change in the weight rule. Machines must weigh no less than 167 kilograms. A 1% tolerance in weight in post-race scrutineering is acceptable.

Wet weather tyres will not be allowed. Again, MA consulted widely with riders, and Dunlop, which has the major share of the tyre market in the Supersport class. MA decided not to proceed with that proposal for reasons of expense and the fact it would have been logistically difficult for tyre suppliers to comply.

When tyre distributors are asked to nominate their tyre for homologation, they will be reminded that the tyre is to be suitable for all weather conditions.

New Class - SuperStock

There is a new class, SuperStock, for C & D grade riders. This class is aimed at being a cheap, introductory level for riders wanting to compete at National Championship level. It is also a cost-effective way for manufacturers and retail outlets to be involved.
