The last flat I had on my bike knock on wood was 1971 in Tampa off I4 back tire blew , Not sure how I didn't crash I went Up the embankment (because it didn't want to turn) on the side road and rolled back down. That was on my Kawasaki 750 Triple two-stroke, It was a bad machine in its time!
PS: that was my fifth street bike.
And probably the reason I have an artificial knee now!
