If you actually read the rules it seems to say that a superkart based on CIK guidelines is legal in unlimited (wings, large driver fairing and center gastank and all) but it doesn’t really say that it is legal in f-125 or not. Since f-125 race in unlimited 2 on sundays I would think any unlimited rules should apply to f-125 other than the engine regs. I’ve always been confused on how that rule is written.
Having said that there have been guys that have run them in f-125 without any problems and as a f-125 competitor I would say bolt on a 125 and come on out. We would love you to race with us.
