I need your input guys. My son is 7 and has about 1 1/2 years MX riding experience on a few different 50s (currently on a KTM 50). He is ready to try a 65, but I am not sure if I should start him off on an older one or a newer one. I found a 2003 KX 65 in good shape. It needs fork seals and is probably overdue a top end job. With a fresh top end, how would this bike compare to the newer KX and KTM 65s at the novice level? Would it even be competitive? Should I stay away from the older stuff if he plans to race it within the next 6 months? I was planning on letting him ride the 2003 model for about a year, then upgrade, but I would rather not touch it if he will get smoked by the newer bikes. On a different note, what do you think a 2003 KX 65 in fairly good condition is worth? The bike is stock.
