If the Wr250 is too tall the duke will be too right? But Dukes are awesome. Especially Daisy. My manliness won't allow me to tell you to get a Gladius. Sry. But used upright nekkids are easy to come by. Of course I'll recommend the Z1000 or Z750. but for a little smaller bike Also a SV650 Nekkid would be a good choice. I wasn't a fan of the S. Or the Yami FZ-6 (upright R-6). I have read good things about the Kawi 650 you mentioned too. Good luck with the bike hunt.
