They all featured Heron heads, one piece forged steel crankshaft, ball main bearings, plain big end bearings, and the conrods run on a common pin, offsetting the rear cylinder to the front by 50 mm. Front and rear barrels and heads are interchangeable. VBH Dell'Orto 25 mm carburettors are fitted to the 350. Both kick-start and starter motor are fitted. The frame is a steel duplex swingarm design, with Ceriani rear suspension, and Marzocchi front forks. The early models had a twin leading shoe drum brake up front (Strada: 200 mm drum, Sport: 230 mm drum), but these were replaced with double 260 mm Grimeca discs on later models.

In November 1981 a 500 Turbo was shown at the Milan Show, producing 84 bhp @ 8300 rpm. It did not make it to production. An enduro version called the Camel 500 was released in 1981. In 1983 the Kanguro 350 was released. In 1986 Moto Morini brought out a cruiser version, the Excalibur, available in 350 and 500 versions. Harley-Davidson became interested in the Moto Morini V-twin as a smaller Harley, but had financial problems, and nothing came of it. The 350 was conceived as a modular design, and single cylinder versions were made. (Looking like the V-twin with the rear cylinder removed) These were the 1975 six speed 125 H and the 1978 250 T Mono, both unsuccessful, as was the later KJ 125 single of 1985.
