No less than three: Buell, Moto Morini and Voxan

. RIP. But more to come, I am afraid, if the "global economy" doesn't turn around... or unless Asian or Arab investors continue pouring money into the western motorcycle industry (Benelli, KTM and others)
On the positive side:
compliments to Norton 
.That brand is causing me to start believing in reincarnation

and best of luck to Horex, which is about to re-enter the market.
With best wishes to all members and lurkers.
