I was mentioning the derailing (I commented earlier but my tablet was being a piece of crap) as the topic segwayed from racing the 300's to different 250cc classes, local tracks, to people wanting to buy used 250's for track riding, etc. If 636's can't race in a 600cc class I would assume 300's wouldn't be able to race in a 250cc class.
And if the 599cc ZX6r's are going to drop in value when the new 636's start rolling out that's good for people wanting cheaper ZX6r's for track riding. But how does that relate to the 636's at all? Same premise here with the 300r's. Sure it'll cheapen 250r's and you'll see a surge of people buying them. It doesn't directly have anything to do with the 300's though.
LOL Or if they required you to keep the awful IRC tires that are going to come stock on the 300r's . That is one of the best modifications you can do to a current gen 250r is throw those shit tires away and get decent tires.
Ah, but they can. Supersport is generally I4s to around 650cc in most club racing orgs. You can club race 636s against 600s, you cannot do the same in the AMA or WSS, etc.
