I bought it brand new from a bike shop that had every type of bike imaginable, the kind of shop where the work area is huge and right out in the open, with the smell of rubber and oil and...well, bike! The owner inflated the tires before I test-rode it, and he handed it off to one of the shop guys to do some kind of prep work (don't know what; I was too busy yapping) while we did the paperwork and payment.
I'm sure the forks were turned the right way. The front reflector prevents it from turning backwards (don't ask how I discovered that

).
I'll check the tire pressure.
I did definitely over-steer and I certainly didn't lean! I was too busy trying to stay upright! I definitely need more practice.
Thanks! I absolutely adore this bike and I can tell it won't be my last!
