Ok, I've done a search, and after going through the first 18 of 462 pages decided it hadn't been covered yet. Searching "overpowered bikes and advanced rider courses" isn't the best search, as it's mentioned several times in every thread on this forum. I'm planning on doing the superbike course, however, I would prefer to do it on the gixxer, as the CB isn't much of a superbike, and I've pretty well taken it to it's handling limit. However, I am on restrictions. Do any courses allow the use of restricted bikes? Given a positive attitude, and will to learn, I don't see why it would be such an issue? Immediately I thought insurance reasons, but further thought provides that most insurance is void on tracks. I could just call somewhere, however I'm at work, and now I've given all you guys something to do!
