My first tip came while pushing it out of the garage. I had just climbed out of bed, and was probably not yet fully awake. There was an uneven concrete seam between the garage and the driveway. When I pushed it over the seam, the balance of the bike shifted away from me. Like people said, once it started, I couldn't stop it. For being naked standards, these bikes are some fat pigs. Now, whenever I can, I keep the bike between my legs. It's good to have a leg on both sides of the bike. I think the high seat prohibits some from moving their bike this way, and leads to tip-overs.
My second one was embarrassing and funny.

After blasting around Wisconsin with some hooligans (from this site), we came to a stop sign. I took my right hand off the handlebar (and brake) to signal that I had no desire to be the leader of this crazy group. Apparently, I did not realize the slight incline that we were on, and started to roll. Then, my right foot lost traction, and over I went. The disorientation, from the rapid deceleration from warp speed, may have been a factor. I laid on the ground embarrassed and laughing, while the other guys quickly picked up my bike.
The third one happend practicing tight, slow speed, turns. I got it into my head that I wanted to be able to do those things that motor cops can do. I also learned that I should only practice that stuff on a bike that the tax payers had bought.
All three were on the right side, the plastic head guard did its job and the bike has has nothing but easily fixable scuffs on a bar end and the passenger peg. If they weren't so minor, I might even think about some touch up paint. I am pretty anal about the bike too.
I was dreaming when I wrote this, forgive me if it goes astray...
