Design
Honda built the AC15 to commemorate the successful 1962 Honda CR110 single cylinder racer. Showing the 1960s style were short racing handlebars and an elongated and low-profile fuel tank.
The frame was a diamond design with a reinforced single front down tube bolting to the engine's crankcase. The top of the frame was a reinforced double-tube over and under configuration meeting a multi-tube box under the rider.
Front and rear disc brakes were standard and unusual for a small displacement motorcycle.
The engine was a rare design for 50 cubic centimeters, having a single cylinder with double overhead camshafts.
A commercial racer was available in 1962 called the CR110 Cub Racing which produced 8.5 horsepower (6.3 kW) from a single cylinder and had drum brakes. A race only version, designated the AR02 or Dream 50R, was imported into the US in 2004.
