Ya the differences really are only the seats, and size of vehicle. Hp roughly the same. Although I believe the 450 engine is used in like 7 different machines including the Arctic Cat, when if im not mistaken the 500 is used in 3 Kymco machines only.
The 450 will obviously maneuver better in the woods being more compact, but both are great vehicles. As far as cf moto goes, I have heard good things about them as well. Almost up to Kymco quality. Yes made in China but a bigger company in China, so its more regulated and parts should be readily available.
I would think the Kymco would hold it's value better if you ever were to resell it. But that's just speculation. Good luck and let us know what you decide to go with.
