Sarris, there are actually two different versions of the SV650. The SV650F has the lower handle bars for a more sportier seating position, but the standard SV650 has an upright seating position, probably much like the GZ (or at most slightly forward).
Easy, just out of curiosity, how do you reckon the S40 is a "sport" cruiser? I wasn't aware that there was anything "sporty" about it.
