Derived from the 250 B, this was MV's first mid-size twin, with a sporty riding position and enough performance to hold its own against larger bikes on twisty roads. It was finished in red. A 1972 road test praised the strong engine and frame but criticised sluggish throttle pick-up and a very sharp front brake, with economy just under 50 mpg.
