I rode my bike up and down stairs fairly often when I was a youngster, mostly just for fun and because I could. My friend rebuilt a Kawi triple on the 3rd floor of the hotel we lived in. Getting it up there was tough back down was easy. His outside door was on the 2nd floor and then stairs down the outside.

I learned all I need to know about life by killing smart people and eating their brains.
Eat right ,Exercise ,Stay fit, Die Anyway!
