Mr. Kackley, I suspect it is a 650 as Yamaha never produced a V-Star 750. Back in the late '90s, they had a Virago 750, but it was discontinued. If you call us with the VIN, we'll be able to let you know exactly what you have. Thanks, and enjoy!
The title should show what kind of bike it is or look up the vin. And the difference is in the cc. If the tire size is not on tire it my be on the motorcycle somewhere if not I found Google a good source of information
