Chi...you rule and summed up my thoughts on this subject suberbly well.
If the frame and engine is essentially the same on the 600 and 750 then why not. The whole aim of the series is to allow accessable racing and IF the basic 750 converted to 675 or 620 does not give an subtantial advantage then it provides another route in.
And maybe means that prices of 600's will not go throught the roof
