I'm learning to ride at the moment, by myself. I'm 29 and had never even sat on a motorcycle until when I bought mine 2,5 months ago.
We don't have MSCs (spl?) here, and at my age a driver licence allows to ride a low cc (until 125cc) motorcycle.
So I started on my own at empty roads at 6am on the weekends, and have only riden 1800km (1120 miles?) until now. The first ride was... interesting. Ok, very scary.
