Changes to schedule at Australian round of World Superbikes Several changes have been made to the schedule for the upcoming Australian round of the 2007 Superbike World Championship, to be held at Philip Island from March 2-4. Forgotten Era (Period 4 & 5) historic motorcycles will make an appearance over the weekend with their inclusion now added onto the event program. Due to low numbers of entries received, the Supersport and Superstock classes will qualify and race together. While these categories have been merged together on the track, both classes will still have their own allocated prizemoney and trophies. Amended Supplementary Regulations and Entry Forms for the Forgotten Era motorcycles can now be seen by clicking on the following link: ~http://www.ma.org.au/AM/SBK_forms~
