How to pivot a large motorcycle in a small space.
Step 1: The Problem
I've got a big motorcycle and a one-car garage that it lives in. I'd ride the motorcycle into the garage at the end of a ride, and then later to go for another ride I'd have to turn the motorcycle around. It's very big and heavy so doing a series of three-point turns was a serious invitation to lose control and drop the motorcycle. So what I wanted to do was turn the motorcycle 180 degrees, in place inside the garage.
This problem has arisen in various other forms in the past (for example, when moving: I'd ride the motorcycle into the back of a U-Haul truck and then be faced with the problem of getting it out again), so it's preyed on my mind for many years.
