Hi, i am thinking of purchasing a 09 zx6r next yr but because ther not out yet no one can answer my question so i thought id post here seeing as the bike iwll be similar. I wanna no whats the biggest difference from a 250 to a 600 besides the power when u wrench the throttle. Is the bike any bigger then the 250? or similar? Do they take the Unleaded fuel/premium? And maintenance wise is it similar to eveyr other bike or are the tired heaps to repair? And with insurance whats that like? Going from a 250 to a 600 will the insurance company charge me more? Thanks.
