So, I'm really interested in picking up a dual sport bike. I've always loved the old airheads (love the /5's ESPECIALLY). Now, I know they didn't make dual-sport bikes back then. Got it. But... the airhead engine is basically unchanged all the way up until, what? The mystic? My question is, on the merits of a DS motorcycle alone, how do the airhead G/S and GS bikes from BMW stand? Like, how good are they REALLY?
