The 850 SS was the last model produced by the MV Agusta factory before closing in 1977, producing only 27 documented examples and the 850 SS was the 750 America with the following changes: EPM Mag wheels, 837cc engine, 27mm carburetors without air cleaners or linking rod, uprated inlet camshaft, triple Brembo brakes, and a dual point Marelli distributor. A batch of U.S. bound examples were outfitted with air cleaners, higher clip-ons, and 850SS decals. This example was purchased by Australian MV collector, L. Duckett who visited the factory in 1977. In 2003 the bike was purchased by Historians Bill Irwin and Ian Falloon, who have documented this example as quite possibly never ridden and the most original of the America series in existence. The bike is prominently featured in Falloon publications. The 47KM shown is likely the test mileage that was clocked on in testing of the original 750 America and subsequent 850 SS iteration. This 850 SS has been correctly stored and detailed to date and remains what is likely the best example of a late MV-Four in the world.
