This 1960 Harley-Davidson Super 10 was purchased 6 years ago from the believed-second owner, a vintage tractor enthusiast, who used it primarily for transportation at tractor shows. Power is provided by a 165cc 2-stroke single with a 3-speed transmission. The bike was stored by the seller for several years, and it is recommended that the tires be replaced and the brakes adjusted before returning to the road. Just over 5k miles are currently shown, of which 500 have been added under current ownership. This Super 10 is offered by the selling dealer with an optional Harley Davidson dual seat and a clean North Carolina title.
The Reparations Act of World War II gave Harley-Davidson the rights to produce a copy of the German DKW RT125, known as the S125 Hummer. The Super 10 was an updated version that offered a larger displacement engine and revised Tele-Glide forks. This example wears an older red re-paint showing dings and paint loss with many touched up areas. The chain guard is missing, and the seller recommends replacing the tires and adjusting the brakes before returning to the road.
Corrosion is visible on the chrome handlebars and speedometer ring. The 60-mph speedometer hosts a 5-digit odometer that shows 5,154 miles.
The 2-stroke 165cc single was factory rated at 5.5 horsepower and is fitted with a Mikuni carburetor and aftermarket air filter. Pre-mix fuel is required, and the 3-speed transmission features a left side shift lever. No service records are available, and little is known of the maintenance history.
An optional Harley Davidson dual seat is included and a cold start and riding video is provided below.
