The Moto Guzzi 500 GP 8 Cilindri took shape under Giulio Cesare Carcano in the mid-1950s. Its four-stroke V8 had cylinder banks set at 90 degrees, yet displaced just 498.5 cc in total. Eight cylinders meant a very different scale here from that familiar in cars.
To make room around the engine, oil and coolant were housed in the upper frame beam. Six gears were initially envisaged, but the engine’s flexibility allowed four or five to be used instead, depending on the circuit.
The factory’s historical account lists a top speed of 275 km/h for the 1957 version. That same year, Moto Guzzi withdrew from speed racing. Its brief racing career left the V8 as a striking example of the engineering experimentation of its era.
The photograph was taken at the 2006 Guzzi gathering. The tank shape, frame structure and multiple exhaust pipes offer a close view of how much machinery had to fit inside a small racing motorcycle.
