A road test and review of the 400 cc Z400 twin, presented as a bigger and better answer to the Honda CB350. The reviewer found it easy to start, smooth to shift and simple to service, with good fuel economy. The criticisms were modest acceleration, poor suspension and seat comfort, and front braking that felt uneven in the wet.
