MODEL HISTORY
While best known today for their transverse V-twin sports machines, Moto Guzzi was founded in 1921 making horizontal single-cylinder motorcycles with integral gearboxes and carried on making the same fundamental design right through the 1960s.
The Sport series was the only model Moto Guzzi produced between 1923-28 and was well-regarded for its good performance, beautiful lines and excellent build quality. The Sport 13 model served as the basis for Guzzi racing bikes entered in the Isle of Man TT races. A novel features is the external flywheel motor, a design that allowed very narrow crankcases and a robust crankshaft. Moto Guzzi engines featured unit-construction, with the gearbox housed in the crankcases and connected by a geared primary drive, which was very advanced for the day.
The Sport 13 has a strong twin-tube frame, a very low center of gravity and excellent handling, for the period. With a curb weight under 300 lbs the Sport offered lively performance and a 60 MPH top speed. The Sport 13 was painted a beautiful green with gold and black pinstriping until its final year, 1928, when it was painted red. The Sport 13 used a Dell’Orto carburetor and Bosch Magdyno, and this machine has full electric lighting and an extravagant electric horn. Total production of the Sport 13 was 4,107 machines.
