Been done before by Paul Rhodes an ex supermoto racer who decided to enter the Moto450 series in the Thundersport races. They actually raced round Donnington with National 250's as they could enter as prototype 4 strokes and he got a 4th place!
He used the forks and running gear from his K5 but some of the other guys run fairly standard bike except for lowering bodywork and raised pegs.
