How did you drop / dump / tip / crash / lay down your bike the first time. What happened and how did you deal with it?
My first near-drop came zinging through a parking lot and swinging out to back into a stall. The loss of momentum caught me by surprise and I almost dropped my first street bike. Not too bad to keep it up.
Horizontal contact came on my second bike at a fuel station. I was passing between a tanker delivering fuel and a wall with a curb when a van appeared quickly from around the corner towards me without an escape route. I locked the rear, did a poor swerve and clipped the corner of the curb and the bike was softly laid on its forward foot-peg that was straightened out later. This was a surprise coupled with poor braking.
Both of these problems came from starting without training on a heavy bike. Now I ride light bikes . What happened when your bike first made horizontal contact?
