nice first bike, best advice I can give is a beginners course. Forces you to go through the paces. RTI was my choice, was good.
Also don't waste money on "upgrades", other than a new lever that looks bent to me...
You might need to upgrade it with a few stickers and get a few more ponies out of it.
Buy a copy of "Twist of the Wrist II" and read it cover to cover..twice. You'd be surprised how much you don't know.
Stay safe and watch out for cagers!
