I saw a couple of adverts for a new 2009 CBR600RR. One was described as 2009 HONDA CBR600RR 600CC 8 which was supposed to be a 2010 model and the other was described as 2009 HONDA CBR600RR 600CC 9 which is supposed to be a 2009 model. So can someone explain what the 8 and 9 mean after the 600CC in the adverts. I'm confused! :?
