Ducati Bipantah is an internal combustion engine made by the Italian motocycle manufacturer Ducati in 1981. It was designed by Pierluigi Mengoli under the supervision of Fabio Taglioni. It has four cylinders and it is ideally formed by coupling two Ducati Pantah V2 engines. It remained a prototype although it had good results during dyno-tests. The project came to a halt in late 1982 when then-owners VM Motori decided not to build the bike the motor was intended.
