The only luck involved in many MC incidents is whether you survive.
BTW, I've had over 12 bikes, both street and dirt. Last Harley was a 1941 side valve, 90 inch flathead, with the engine built by Big Daddy Roth, of the Car-toon Mag fame of the 1960s. I have had my share of experience with bikes of all types.
The flathead, (last of the Harley pig iron), was originally an 80” motor.
You're wrong.
