FX originally saw the Mountain Moto as a defense product, but for a number of reasons we have decided to focus on the off-road and dual sport/recreation markets at first.


However, if “friendly” military and relief organizations are interested in our commercially produced models, we’re happy to talk, in defense language of course, using plenty of serious words like gradeability and TLAs (three letter acronyms)…starting with a new name…SLM.
