I still have a Harley, and hadn’t dropped a bike in 40 years… I didn’t study how to pick up a bike until I got a rather large dual sport BMW R1250GS Adventure with a 8 gallon tank. It is a bit like going off road on a Honda Gold Wing. My greatest fear was trying to pick it up, if I dropped it. It has crash bars all over it, so I figured it was designed to fall over in the dirt. I wouldn’t have ever got it picked up, without doing it the right way. I can’t arm and back lift 750lbs anymore without casing serious injury to the back.
The squat and push away with the legs and butt is a must to learn.
