Can't see what the problem is, introducing a class that was fading out years ago due to lack of (useable) parts, so they adapted the rules to suit so oversized motors, usd/radial front ends etc, with boundaries being pushed tuning wise the bigger parts become harder to get, then sub 64hp (std) class introduced which was popular, but still allowed the chassis changes etc.
So what's going to attract any of these to crmc, no warmers, no wets, no other classes to run in and having to rebuild their bike to run to regs, can't see them flocking in, other than some oddball 2t stuff.
