The MV Agusta F4 was the motorcycle that launched the resurrection of MV Agusta in 1998. The F4 was created by famous motorcycle designer Massimo Tamburini at CRC (Cagiva Research Center), following his work on the Ducati 916. The F4 is unique with its four pipe undertail exhaust, single-sided swingarm, large front forks (49 or 50 mm diameter) and traditional MV Agusta red and silver livery. The F4 is also one of the only production superbikes to have a radial valved engine.
