I think the Vulcan 500 is a really good choice…it will have the most oumph out of all of the suggestions, then the Star 650, the Honda VLX 650 then the Suzuki Savage/S40…the Kawasaki engine is the same engine as the Ninja 500 with slightly different tuning, the Yamaha and Honda are V-Twins that will have that “rumpity rumpity” sound you would expect from a cruiser, and the Suzuki is a single cylinder 650…lots of low down torque, but might not be the best choice for longer hiway cruising (vibey and might run out of breath, depending on cruising speeds)…the best suggestion is to go and sit on some of the bikes to see what fits you…you need to feel comfortable on the bike, and take your girlfriend (although I wouldn’t suggest riding two up until you have atleast a couple thousand miles under your belt…just a suggestion)…you will want her to be comfortable as well (mama not happy, ain’t nobody happy )
Later.
