I have heard nothing but good things about TM's, probably give KTM a good run for their money, it doesn't seem like they want to dive into the US market though, perhaps that is what is keeping them alive, staying small.

Pete Vetrano, the US importer, is a friend of mine. TM is definitely a small company, diving into the US market with a plated dual sport (or even green sticker) is a huge commitment with CARB testing, etc... Most TM's in the US are sold to people who race.
