Had to borrow this photo from suzukicycles.org, but my first 'real motorcycle' back in 1965 was a 150cc two-stroke twin Suzuki S32. In those days synthetic oil was rare, so it was common to add outboard motor oil to the gas. The result was fouled plugs every 80 miles, but the routine was accepted. The little bike was PDQ for the displacement, easily outrunning the similar Honda CA-95 150cc four-stroke.
