ALL OF THE POWER, NONE OF THE EXCESS. Suzuki’s DF150A was founded on its inline, four-cylinder DOHC powerhead featuring a LARGE displacement. Suzuki’s engineers targeted this big block motor, building it to be one of the lightest four strokes in the 150 HP class, beating out the performance of heavier competing frames. This exceptional model comes in Nebular Black and New White and your choice of mechanical or digital controls.
