A while back, we wrote about how Honda used miniaturization with the RC166 to create a 6 cylinder 250 cc Grand Prix bike in order to compete with the two strokes. But they weren't the first to attempt this approach. Moto Guzzi had given it a shot over a decade earlier.
Moto Guzzi is largely known today for their dogged commitment to the longitudinal V-Twin engine on all their bikes. That clearly wasn't always the case. The Moto Guzzi V8, also known as the Otto (for 'eight') motorcycle, was designed by Giulio Cesare Carcano, specifically for the Moto Guzzi Grand Prix racing team for the 1955-57 seasons. The Moto Guzzi Otto motorcycle and its engine represent a unique and historically significant engineering milestone.
