The 2 1/2-horsepower, 1-cylinder, 2-cycle, air-cooled engine has a 2 1/4-inch bore and a 2 3/4-inch stroke, providing a total piston displacement of 13 1/2 cubic inches. A Brown and Barlow float-feed, single-jet carburetor, with auxiliary air control, is bolted to the inlet port at the front of the cylinder and is controlled by a pair of levers on the right handlebar. The motor is lubricated by a mixture of oil and gasoline in the fuel tank. A Bosch high-tension magneto, with spark plug, supplies the ignition.

The cycle's frame is of heavy-gauge, seamless steel tubing, brazed at the joints; wheelbase is 54 inches. The engine and gear box are secured in the frame by two large suspension bolts. The gear box, which is integral with the aluminum crankcase, contains a set of two-speed sliding gears of chrome-nickel steel, a heat-treated, alloy-steel worm with a titanium-bronze worm gear, and a clutch composed of 13 disks of hardened and ground steel. Low ratio of the gear box is 10 to 1; high ratio, 6.1 to 1. The transmission gears run in an oil bath.

The clutch is engaged by moving forward a lever on the left. The brake is operated by depressing a foot pedal, also on the left, which contracts a band on a drum on the left side of the rear wheel; and the gears are changed by means of a foot pedal on the right side. A kick starter is attached to the left side of the gear box.

The rear wheel is driven by a roller chain from a sprocket on the output shaft of the transmission, on the right side of the machine. There is no guard over the chain. The steering fork is fitted with a coil spring and its tubular handlebars have rubber grips. A cylindrical muffler, of cast aluminum, is mounted in front of the crankcase.

The wire-spoke wheels have metal rims and mount 26-by-2 1/3-inch clincher tires (of the 1920s) that have been equipped with new butyl-rubber inner tubes. Each wheel has a mudguard, and there is a stand at the rear of the frame. A cylindrical fuel tank, equipped with a shut-off valve at the bottom, is suspended from the frame over the engine; and a small, metal toolbox is attached to the rear underside of the tank.

The footrests, adjacent to the brake and gear-shift pedals, are rubber covered. The saddle is a Mesinger "Auto Cushion." The motorcycle has no battery, generator, lighting equipment, or warning signal. Its total weight is about 150 pounds.
