Yamaha 305 and tough guys

In the mid sixties, one of my first experiences with motorcycles and its culture was a bunch of guys riding Yamaha 305's. I remember the slick back hair, white t-shirts, jeans, white socks, and Beatle boot type footwear. I knew a guy down the street that had a BSA Goldstar, but it was the Yamaha's that made the greatest impression. I wonder what ever happened to these guys tearing around the Grove spreading mayhem?

Probably sales reps...
