Treb, Did you buy it yet. If not, who has it and where is it as I will. Cheapest I can find around Philadelphia is $3990 and it is an '03. Since th '01 is no different ( green tank instead of black ) the deal is too good. Get it now.
The only change (and I am not sure) might be the plating in the cylinder. I read a post from Eric Gorr that said Kawi developed a new design for 03. Not sure if kdx is part of it. Here is the post below..
