The Support Races at the 2007 Superbike World Championship round at Phillip Island are not part of the 2007 Australian Superbike Championship, meaning that Superstock competitors are required to use the tyres from the ‘2007 Tyre Homologation list for Road Race’. Also, with the combining of the Supersport and Superstock classes at the event, Superstock riders will be allowed to run wet tyres if the race is declared wet. If there are any queries relating to these or any other rules that will be in effect over the weekend of the Superbike World Championship, please do not hesitate to contact Daniel Hutchinson on 03 9684 0500.
