Congrats on your first bike!!!!
Good decision on getting a cheaper used bike to start with. A lot of kids buy brand new r6's and wreck them by the end of the week. It sucks for them, but good for me because I can buy their used parts on E-bay.
My advise to a new rider. WEAR YOUR SAFETY GEAR. On real rides we wear full leathers. But just around town, MINIMUM, I don't leave the house without a good pair of riding boots, leather gloves, solid leather jacket, (don't go with that textile shit or ICON garbage) and of coarse a good helmet. Expect to have a few get offs.
Riding without gear is like going on a steroid cycle without anti-E's. Nothing may happen, but if it does, you're PHUCKED.
Believe me bro, shit happens.
Ride safe.
