This 1976 Kawasaki KM100 is a street-legal mini-bike that was acquired by the selling dealer 6 months ago. The bike is powered by a 100cc 2-stroke single with a 5-speed transmission, and the previous owner is said to have performed a reconditioning with new paint, decals, tires, sprockets, and a carburetor rebuild. Prior to offering the bike for sale, the seller tuned the carburetor and added a new spark plug. Approximately 3,700 miles are shown, of which 100 have been added by the seller. This KM100 is offered by the selling dealer at no reserve with a clean Vermont title.
Under prior ownership the fuel tank and fenders were re-finished in matte white with black lettering. The tires were also replaced and the electrical system refreshed. The seller notes a patch on the seat vinyl, and corrosion on the headlight brackets.
The steel fuel tank holds 1.5 gallons and features new Kawasaki decals. Paint loss can be seen to the logo on the side cover.
The ignition switch is located near the 70-mph speedometer which contains warning lights for neutral, high beam, and turn signals. Just over 3,700 miles are shown.
Power comes from a 100cc 2-stroke single with a 5-speed transmission. The engine requires pre-mixed fuel, features a rotary valve, and was factory rated at 9 horsepower. The previous owner reportedly performed a carburetor rebuild, replaced the sprockets to improve the top speed, and added a custom machined aluminum exhaust tip. Before this auction, the seller adjusted the carburetor mixture and replaced the spark plug. No service records are available but a walk-around and riding video can be seen below.
