 Amongst the options were big-bore kits to bring the capacity up to 837 cc (as used on the MV 850 SS Monza), Dell'Orto carburettor kits, exhaust systems, drive chain conversions, the lightweight Magni frame, which was based on Magni's design for the F750 S Imola racer, EPM wheels, 4ls drum brakes and Brembo disc brakes.On the MV 4-cylinder engines the cylinders were cast individually.By casting the cylinders in pairs, Magni was able to fit larger liners and increase the bore.
