Welcome to the Vulcan madness Mr Monte. That is a nice looking bike. It looks like the previous owner has cleaned up rust off the speedo and tach rings, and painted them black. There have been several other members here who have done the same, and posted pics of the process and results. I need to clean a little rust off of mine and either polish and wax them, or paint like yours.
The vn750 is my first bike after having a mc licence for 41 years. It has a lot of power for someone who is just learning to ride, as you say your wife and sons want to do. You do not indicate the age or physical size/height of any of the prospective new riders. It may or may not be the "ideal" motorcycle to learn on, depending on several factors, in my humble opinion. For instance:
-Does the newbie have any experience with a manual transmission and clutch in an automobile.
-While sitting on the seat, can the new rider comfortably reach the ground with both feet.
-Does the new rider have sufficient strength to catch, stop, and push the bike back up with one leg from a 45* lean angle, when they lose their balance at a stop or slow speed. I mention this, only because it is inevitable that a new rider will lose their balance occasionally while learning to use the friction zone in moving off, negotiating the slow cone weave, the figure eight, U-turns and other slow speed manouvers.
The stock vn750 weighs about #500, ready to ride. The MSF Beginner Riding Course seems to use bikes such as the Honda Rebel 250cc, which I suppose weighs about #300, and is much easier for a learning rider to recover from a mistake.
Please do not take this in any way as trying to dicourage you or your family from learning to ride the Vulcan 750. I only offer you a "heads up", that you may want them to look at learning the basics on a smaller bike, and getting some experience before transfering that knowledge to the VN. You don`t want really want them to scratch up that pristine paint on your VN now, do you?
