+1 on Triumph. The new Bonnevilles are the only real standards I can think of on the American market. Even the Ducati SportClassics have a pretty aggressive riding position. The Royal-Enfield thumpers look nice, but I've heard reliability isn't the best. Saw a guy on the streets of Santa Fe once kicking his Bullet over again, and again, and again. Never did see him ride away.
A lot of manufacturers have done the "naked" bike thing... most obvious is the Ducati Monster, but there are others as well. I learned to ride on a Suzuki GS500E, which was a decent looking bike - no fairing, but a sporty frame. I'd feel bad for a passenger, though, since the seat kept sweeping up as it went back.
Rumors abound about Honda's new CB1100F coming to the U.S. It's a good looking bike - lots of pics on the forum.
I like the BMW R1200R, but the price tag is definitely up there.
