Possibly demand, a lot of people I know were not impressed when they dropped the 636....I bought an 09 and would not consider buying another 600, but since its a 636 I sold my old bike and am buying one...A lot of my friends have 2 ZX6R's, and prefer the 636's much more...So its not just me
just get yourself a 750 finally johnny. its time to give kawi a rest
