The  MV Agusta 750 Magni bored out to 840cc and equipped with chain drive, a new engine cradle, and that simply beautiful exhaust system. Its pedigree is impeccable: Magni was Count Domenico Agusta’s Direttore Sportivo del Reparto Corse, the head of the MV Agusta racing team. When Agusta pulled out of racing in 1976, Magni set up his own company: first producing racing parts, and then selling modified versions of contemporary motorcycles. These sensational machines were based on the Honda Bol d’Or, then BMW boxers, Moto Guzzi twins and finally Suzuki fours.
