1921 - 1922
The Dikappa's Tipo 66 inline-four engine was based on the Kappa's Tipo 64, but had two parallel overhead valves per cylinder instead of side valves. Displacing 4,940 cc, it developed 87 hp at 2,300 rpm. The Dikappa was offered with a light torpedo body, of walnut wood construction covered with aluminium sheet metal; wire wheels also contributed to the weight reduction. Top speed was 130 km/h (81 mph), up from the Kappa's 125 km/h (78 mph).
