I'm getting my L's this weekend and am looking to buy a CBR250RR to learn on for a year or so. In my research I've come accross a few things i'm not sure about that I thought the more knowledgeble members here could shed some light on. A '91 RR is classified as an MC22 right. When I do a vicroads status check on any '91+ CBR250RR I get a matching engine number like MC14E1xxxxxx. I thought the MC14 was a previous model? Is this standard? What am I missing here? I've also noticed that the VIN numbers come in the following formats: JH2MC22U7WM102487 6F91MPORTVHPP0107 6MAH1102GK12Y2039 6MBH0NDAAM25Y4976 To me the first one looks the most ligitimate and I know the differences are due to the 100's of ways these bike have been imported into oz over time but do I need to worry about what format the VIN is in? As long as it matches with Vicroads it's ok? How do I know if i'm buying what I thing I'm buying as in a real CBR250RR with the right engine etc as it was originally built? Just tell me if I'm being overly cautious.
