I'm curious as to how much of this stuff is out there staying at home - are we really talking about a lot of bikes here?? Or is it realistically not many at all and therefore a redundant argument??
Having no real interest in Thunderbikes I may see this differently. The 125s have to run cross period races mixed up with some weird and not so wonderful other bikes. Why not run cross period Thunderbikes all in together? As I have suggested before each bike can run a smaller number designating the period that it belongs in. Each period can have its own race points but within the overall race. With the wonders of electronic timing it is not hard to figure out who finished where in each period race. The "period" numbers will help the spectators (yes, we still get some)identify what they are watching and may even create some sort of extra interest akin to the Holden v Ford rivalry that keeps the V8 Supercabs so popular.
