well, from the short female PoV
when i started my bike search, the Suzuki 650 was reccommended to me by more than one source. they say it's a great bike.
the Ducati has the 'soul', and the 'intangible something' that might attract people, but the SV is reliable and all around yadda-yadda.
that said, i can't sit the SV650. would have to modify the seat and suspension.
i'm just.. not interested.
i'm going for the 'intangible something' and the bike set up the way it was built. climbed on the m620 Dark in the showroom and it just *fit* perfectly, seat, reach, balance.
my advice, go sit them, check them out. ^_^
