Well, to this day, I have not ridden a mini-bike, a scooter, or a moped. The first vehicle with an engine and two wheels I ever rode was a CB100, but I was under 18 and could not buy a bike without my parents' consent, which I definitely did not have.
The second time I rode a bike was the day of my 18th birthday. I rode my bicycle to my local Honda dealer, picked out a used CL450 and an orange Bell RT helmet, and the salesman drove me to my bank to take the money out of my savings account.
I then rode illegally down to the DMV and got my bike license. Remember, this was only my second bike ride ever, but I learned enough on the ride down there to pass the test: a wiggle through cones, stop, and make a left turn, after an easy written test.
Not mine, but same colors and stripes.
