The PBRAs rules still have some issues...

Pitbikes are defined as 54" or smaller wheelbase, 14" or smaller rear wheel? Then in the tech requirements they clamp 10" rear wheel machines to a 45" wheelbase, 12" to a 49" wheelbase, and say 12" rear wheel is the max. No classes allow 14" wheels. Looking closer, I also see they fail to mention anything about liquid cooling or running a two stroke... Pardon whilst I prep my 188cc water cooled two stroke in a closed cradle frame, 12" rear wheel monster. :P

Foot peg pivot points can't be more than 3 inches from the frame... Thats a rule that can be interpreted many ways, and I can think of lots of scenarios where even the kindest reading rules out many safe machines.

No titanium frames? Thats an odd exclusion.

"Forks must be adequate in strength and size for the pit bike and it's use." Guess that rules out all stock 50 style front ends. :P

"No radio communication with riders is permitted." Every rule has a name to thank for it, I want to hear the story behind this rule and how it crept into pitbike racing.

It's a nice try, but still way out there compared to the ideas and rules in use in 99% of the pitbike races actually occurring. I think the standard laid down by the Master of Minis series is closer to ideal than the PBRA setup.
