Benelli 750 SEI 1979 Parts & Accessories

Founded in Pesaro, Italy in 1911 by Teresa Boni Benelli and her six sons, Benelli stands as one of the oldest operating motorcycle manufacturers in the world. Originally established as a repair workshop, the company produced its first complete motorcycle in 1921. Benelli quickly earned legendary racing status across Europe, dominated by Tonino Benelli on their 175 cc overhead camshaft machines and later claiming Grand Prix World Championships in 1950 and 1969 with iconic 250 cc four-cylinder race bikes. In 1971, Argentine industrialist Alejandro de Tomaso acquired the brand, leading to the creation of the famous multi-cylinder 750 Sei—the world's first production six-cylinder motorcycle. After a late-1990s revival marked by the aggressive three-cylinder Tornado superbike and TNT naked series, Benelli was acquired in 2005 by the Qianjiang Motorcycle Group (QJ Motor). Today, engineered in Pesaro and produced with global manufacturing scale, Benelli has enjoyed a massive global resurgence led by accessible, versatile adventure and naked streetbikes like the best-selling TRK 502.
