It was the late 1990s and visionary designer Massimo Tamburini was on a roll. His masterpiece Ducati 916 had been released in ’94 to a hailstorm of critical acclaim. Not content to rest on his laurels, _Il Maestro _whipped up the MV Agusta F4 as a dramatic encore. The 749cc four arrived in ’98 in classic red-and-silver livery with an underseat organ-pipe quad exhaust and a single-sided swingarm. The F4 succeeded in re-establishing the MV Agusta brand after its purchase by Cagiva, Ducati’s former parent company. Ferrari contributed to development of the engine, which featured hemispheric combustion chambers with radial valves. The F4 grew to a full liter in 2005 with the production F4 1000S. Output was a claimed 166 bhp.
