2.4.1 section 3 - Supertwins GTU

Modify Supertwins GTU to match the Moto America Pro Twins class.
Up to 850cc twin (excluding the 848)
Weight restrictions for 800cc and above

If we choose to modify only one class, STGTU makes more sense than LWGP because whatever bike you race in the Pro Twins ruleset will also be good for Thunderbike and STGTO, both on Sunday.
