Yeah, Colorado Class would be the ticket. But you would still have to deal with the Sportsman folks on their 4 cylinder 600s and 1000s (they start in a second wave behind Colorado Class). Despite that, I think everyone would agree that Colorado Class/Sportsman is a pretty mellow group.

Interesting side note: Apparently, the new Ninja 250 class "Rent-a-Ninja" program at WSMC is doing very well. Probably don't have the critical mass to make something like that work in Colorado, though.
