I don’t think they make a Virago 500….they used to make a Virago 535 but it’s been over 10 years since that was in production. It was replace by the V-Star 650. The only 500cc cruiser I’m aware of is the Vulcan 500 which btw gets rave reviews by just about everyone. Other cruisers of similar size are the Suzuki S40 (650cc single), the Honda VLX600 (last produced in 2007) and the aforementioned V-Star. IMO the Vulcan is easily the best bike of that group, though it lacks a bit of the classic cruiser styling being a parallel twin vs. a V-twin as you mentioned. But that 500cc engine is pretty sweet, I’ve put quite a few miles on a Ninja 500 which has the same basic engine and it is easily controlled but has plenty of power.
BTW if you are looking to go used the Virago 535 seems to be a well respected bike, and actually had more power than the 650 that replaced it according to what I have read.
Good luck with your search.
