So you have a 2-stroke liquid cooled twin. 4-stroke twin up to 700cc? Nope. 4-cyl up to 500cc? Nope. Air-cooled twin up to 1000cc? Nope. Single? Nope.

Nothing ambiguous about it - the TZ250 isn't legal for that class.
I don't disagree at all. But that was my position at the time. The TZ is rightfully not legal in that class. But for the fun factor and battles it was awesome. I'm going to race up a class next time out and ride in Formula Middle Weight. Will most like learn a thing or two from the faster company than really drop the hammer in F2 and LWSO.
