I think you have to import them yourself to the US. They make two strokes and our country dont want anymore twostrokes being sold here. Well except for what is make in the US. Like weedwackers and chain saws. But they dont want any twostrokes imported to the US anymore. They are great quads. And I have heard they are interchange with the TRX250R. They get a bad rap because nobody ever heard of them.
