Hi guys Just looking at a dirt bike for the girl friend to rip around on and join me when i go riding. I was looking at the crf150f and wanted to know if it there were any major changes in these bikes over the years, ie. will say a 2004 be almost the same as a 2009? Just wondering if were better off buying a new one 3400 versus say a used at 1700 what are your opinions. Its just going to be used for putting around in trails nothing serious, just wanting a bike anyone can hop on and have fun.
