Few people know that Harley Davidson once produced a rare scooter model that sold from 1959 as a 1960 model until 1965. The Topper was the only scooter model ever produced by Harley and is certainly a real classic today. It featured a 9hp two stoke engine that required premixing oil and gas. The Topper's engine measured out at 165cc, and it featured an automatic CVT transmission. The bodywork was part stamped steel, part spray gun painted fiberglass. Only 3,000 total Topper scooters were ever produced before production was suspended. It rates as one of the rarest Harley products ever built.
