The Principe Alvino V1 is a sport bike due to appear in Grand Theft Auto VI, first shown in an official screenshot of Jason Duval riding a green example with a worn number 76 livery while holding a pistol. It appears to be based primarily on the Ducati Panigale V2, with headlights influenced by the Aprilia RS660 and further details drawn from other Ducati machines such as the 959.
