What classes are GP250 legal?

[Racingxtc7]

The only class I could find was LW GP! Are GP250 bikes only legal in one class?!?!?

And GTU, Middleweight Grand Prix, Unlimited Grand Prix.

This is for a TZ250 or something, right?

Some error in refering to the Aprilia RS250 Cup bikes at Grand Prix motorcycles when they are not.

250GP bikes (TZ250, RS250, etc) are legal for lightweight GP, middleweight GP, unlimited GP, GTU and GTO.
