Nova Challenge Classes 1 & 2

A CONTROL TYRE HAS BEEN WITHDRAWN FOR CLASSES 1 & 2

 

Currently, any road legal tyre is permitted. Tyres “for competition use only” and those without the ‘E11’ marking, designated for road legal tyres, will not be permitted at any time during the event.

Tyre Update - From 2010 an exception for non road legal tyres is being introduced. Competitors will now be permitted to us a "cut slick" Michelin X FR2.0 available at a cost of around £30 from SW Adair Tyres (028 81648428 or 048 81648428). This is to allow a lower cost alternative to the widely used Toyo Proxes R888 tyre.
