I took my test in 1970. I'd been riding my 1969 650 BSA Firebird Scrambler for several months without a license or insurance (too young to know better). Finally borrowed my neighbors Honda Trail 90 and took the test. That bike made everything easy to pass. Just 1 week after getting legal, I plowed into a car coming toward me that made a sudden improper left hand turn. No turn signals, just turn and go. I plowed into their right rear quarter-panel ruining the front end on my Beezer. No injury to me though. Glad I'd gotten my license and insurance....
Here's a pic (not mine) of the bike I learned on. Wish I never sold it after it was fixed.
And here is a pic (not mine again) of the one I took my test on...
