heheh they are the factory I am the dealer they dont need to explain anything to me ....
most likely simple reason. that they have so and so many models they want to carry, have in stock for their dealers and not more. The good sellers stay in the program the ones which didnt sell as well get replaced by new models ....
Also Dahon bases their models on dealer feedback at the trade shows, if most of their dealers dont get exited about one model it most likely doesnt get carried over.
