Honda AC15

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.
