Honestly you have to go check some bikes out. I find the 650 star to be small...smaller than my HD sporty. The honda 750's are a bit bigger than the star but still a touch too cramped. The 900 kawi and 950 star feel pretty big but not huge. If you want a larger mid size cruizer look there or a suki c50. If you decide to go the HD route try to find a 1200 you'll not regret it. CTX is a comfy bike...ugly and not out yet but could fit your bill too.
