Yes it has happened to me twice. The second time is just what you described but I went down on the right side trying to navigate a small turnaround. I have come to accept the fact that I’m getting older now, and the weight of this bike was getting to be too much for me to handle safely.
I am almost 61 years old and it was time for me to lighten up. I have traded my 15 R3T for a 2020 Kawasaki Concours.
I have trimmed about 170 lbs off with the new bike. The handling of my new 1400 is so much lighter, and I can push it around my garage so much easier too.
I will miss the big Triumph, but I now feel like my new bike is a better fit for me. Here’s a picture of my new Concours. Don’t mind the messy garage!
Good luck, Eric
