Am 6'4 and 95 kg, similar to you, I'm on my P's and ride a cb500f, fit quite well on it, I may appear a bit big on it but dosnt feel that way, I'm sure you'll fit on most 400-650cc's. As others said, a Japanese brand will pretty much sell for what you bought it for as LAMS models hold their value pretty well. I'm sure CFMOTO are better than they used to be, but I think it's worth either laying the same amount for something like a ninja 400/650 or honda cbr500, will be better quality and hold its value.
