About MV Agusta

Country of Origin: Italy
Founder: Count Domenico Agusta
Best Known For: Grand Prix royalty and sensual modern sportbikes (F4, Brutale, Superveloce)

Company History

MV Agusta’s legend was forged on the racetrack—surreal streaks of GP titles in the 1950s–70s—and later reborn as a design house for desire. The modern era began with the F4: Massimo Tamburini’s sculpture of aluminum and exhausts, paired with sharp, rev-hungry inline-fours and top-shelf components. Naked Brutales brought that intensity to the street; triples added agility and tractability; the Superveloce wrapped contemporary engineering in retro glamour. Behind the romance sits serious hardware: trellis/plate frames, radial brakes, advanced electronics, and suspension that can be set to speak clearly. Volumes are small, finishes meticulous, and the ownership experience leans boutique—part of the appeal for connoisseurs. Historically, MV Agusta marries racing pedigree with couture design, proof that motorcycles can be art objects without denying their duty to thrill. Riding one feels like inhabiting a lineage: a front row to Italy’s conviction that speed and beauty are not separate ambitions.
