This 1960 Moto Guzzi Stornello Sport 125cc was reportedly refurbished by the previous owner of a period of ten years, and was completed four years ago. The selling dealer acquired it from the previous owner’s son four years ago, and the bike has covered a reported 200 miles since completion. The bike is finished in red over a black frame, and is powered by a 125cc single-cylinder engine paired with a 4-speed transmission. A Keihin carburetor is fitted, and a factory-type Italian carburetor is also included. This Moto Guzzi is offered by the selling dealer in Texas with a clean California title.
The bike was refurbished under previous ownership, including a repaint of the bodywork and refinishing of the black frame, suspension components, and trim. The bike is equipped with a single pea-shooter-style muffler and leading-shoe drum brakes.
Steel-rimmed wheels measure 17″ in diameter front and rear and are fitted with 2.5″ front and 2.75″ rear tires. The bike retains factory lighting and a rear license plate mount, and is equipped with a black vinyl tandem seat.
Instrumentation consists of a single Veglia combination odometer and speedometer, on which the needle has broken off the spindle. 235 miles are shown, approximately 200 of which were added by the seller. The bike is equipped with a 6-volt electrical system powered by a flywheel-driven magneto.
The 123cc single-cylinder engine features an aluminum cylinder head with two parallel overhead valves, and factory-rated output was approximately 7 horsepower. A Keihin carburetor is currently fitted, and a factory-type Italian carburetor in need of a rebuild is included. Power is sent to the rear wheel via a 4-speed transmission and drive chain. A tune-up was performed under current ownership.
