I think we should also be concerned about the dealer network. The company probably has insurance to cover this kind of thing. But even if the factory rebuilds this means many months without new bikes or parts. The best dealers out there seem to be the ones that only sell Triumph, or have Triumph as their main brand, but with nothing to sell they will have to take on new lines or go out of business.
The fire is a tad suspicious given the claim that they are considering moving production "abroad." I wonder what "abroad" means? Someone mentioned shifting production to Asia, but I can't help but wonder if they weren't considering production in North America? This is probably their single biggest market now, especially for the Bonneville. I can see this hurting Triumph's prestige, though personally I don't care where they are made so long as they have as good or better quality as the current products.
