I think you can get the 200 in Canada. From what I have learned, the 200 has more top end, and the 220 has more low end. Not sure exactly why Kawasaki makes two models, with such close displacement.
They actually make the 220 to give it more low-end grunt. I'm not sure why they don't step it up to a 250 just to be competitive.... They did have a KDX250.
They stopped shipping 200's to Canada when the 220 was released back in 96/97. So only 220's are available in Canada and the newest 200 you could find would be a 96 I believe.
