The MV Agusta 750 Sport America (also called MV Agusta 750 S America in Germany, and MV Agusta 800 S America) was a motorcycle manufactured by the MV Agusta company from 1975 to 1977. Derivative models were produced in limited numbers until 1982.

In 1975, Chris Garville and Jim Cotherman of Commerce Overseas Corporation, the US MV importers, initiated the new edition of the MV Agusta 750 S. The appearance should be more closely based on MV's racing machines, with the aim of increasing sales in the US. Within 50 days, the designs of the two entrepreneurs were implemented at the Gallarate plant.

The core of the engine was formed by the crankcase rack. In the rack was mounted the nine-piece crankshaft, assembled in six bearing blocks using roller bearings, as well as the spur gears in the control tower for driving the two camshafts. After loosening twelve nuts, the units mounted on the rack could be lifted out. Bore was increased by 2 mm over the 750 S models to increase capacity to 789cc. Individual light alloy cylinders (a block was used on the 1100 Grand Prix model) with cast liners were used with Borgo pistons. The two valves of each cylinder were actuated by bucket tappets from two overhead gear-driven camshafts. Particularly striking was the fine ribbing of the cooling fins on the sump as well as the oversized cylinder head acting by the double camshaft drive. The gearbox was transversely mounted in a cassette. It was connected to the shaft drive to the rear wheel via a spiral bevel gear angle drive. The engine was, like all MV four-cylinder models, assembled by hand.

The diameter of the Ceriani telescopic forks was increased from 35 to 38 mm, and double disc brakes were used on all models. The gear shift was transferred to the left side of the engine. The red livery, the suede-covered seat and the Smiths round instruments made this a sporty and elegant motorcycle.
