Ed, hit the MSF Basic Rider's Course and ride the Rebel 250s they have. You'll very quickly realize that you don't want to own one of those, as yours. Some courses have other bikes, too. Local ones here have the Rebels, Kawi Vulcan 125s (the BN125), and Kawi KLX250 dirt/street bikes. When you get to the course, get there early, and pretty much ask if you can use a specific bike - they'll let you.
After that, buy a used bike for your first bike. After riding BRC, you'll kind of get an idea of what you might like, and definitely what you don't like. Hit that course first, then try to narrow down what type of bike you want to buy.
If you buy used, there are many advantages - cheaper insurance for a new rider, no break-in period, ride it without as much worries.
You also have disadvantages - you don't really know what you're buying, besides what the seller is telling you. It might need work, ir might fall apart, and you have no factory warranty period.
If you buy used, there are advantages - most manufacturers have a 12-month factory warranty that covers pretty much anything. Keep in mind, if it's something the rider could have caused, or could have prevented, then it's not covered. Tires, brakes, clutch - not covered. Pretty much everything else is covered.
There are new bike disadvantages, too - higher initial purchase price, higher insurance rates for new riders, and when you scratch that thing, you're gonna be pissed. New parts cost a hell of alot of money, with body panels and gas tanks that will shock you on prices! When that new bike gets dinged up, and you make an insurance claim on it, it'll cost alot to fix, and you're making a claim as a new rider...
I'd suggest buying used for the first one, get a few years of skills under you, then buy something new down the road.
