I'm glad you are OK, I too broke a collar bone when I was in high school jumping my dirt bike, I hit a tree in midair and the bike landed on me. The ride home I saw a lot of white light and stars, boy that hurt, and the recovery, man that was not fun, no cast, they put me in the strap device that is like a board on your back and it pulls your shoulders back and up. Hurt to breath, and I've broken more bones than I can count, both legs multiple times, both arms several times almost all of my ribs, all of my fingers and thumbs, etc, but the collar bone break was by far the most painful recovery. I hope you don't have nearly as bad a break as I did.
Road street bikes for many years, rode fast on track days, had a couple of times when the bike and I parted company, but never any injuries, but on the dirt bike, well, yeah, I did a lot of damage.
Even on your Harley riding at sedate sane speeds you can certainly still get in trouble, recently a cycling buddy with years and years of experience riding on the road went over a small curb at a bad angle, it had recently rained and he lost it, went over the bars at maybe 20 mph, and he shattered his wrist and arm. Life is not going to be guarantied safe no matter what you do, so you should do what you enjoy and mitigate the risk the best you can.
