I did not ride the strom, but rode the SV. Very nice! Plenty power, sweet handling. I have sat on a 650 strom, and found that there is no room for the uh, boys. Too swoopy of a rear seat.
Also, the fairing is insect-looking, and could not be readily modded to provide good protection on a long road trip. I realize that's not the bike's intended purpose.
I have long wished that suzuki would put those sweet motors in a retro frame ala Ducati GT or Guzzi V7Sport, with twin shocks, long adjustable clipon swanneck bars, a slab cafe tank and long flat seat. Shaft drive and tubeless tires a bonus. Especially a 1000
