Its not a slow bike, a recent comparo article had the HD Street Glide at 0 to 60 in a bit over 5.8 seconds, the Stratoliner Deluxe 0 to 60 in 4.1 seconds.
From my experience, it really gets up and moves.
Its a riders bike, it has lots of room, comes all decked out, and if you shop well, you can get a hell of a deal on a brand new one (no miles). Try and get this much bike for under $13K.
