Ducati 250 24 Horas was an adaptation of the model Mach I, which was manufactured by Ducati Mecanica. It was the first sport bike with a 5-speed gearbox and fuel tank made of fiberglass. During the production the motorcycle was repeatedly modified – a dashboard with speedometer and tachometer, more effective brakes and many other things. Ducati 250 24 Horas was fitted with a 250 cc 4-stroke engine.
