The new FSa-56 from O.S. is the first engine in a completely new series of advanced four strokes. The FS `Alpha' series draws on the experience gained from the Surpass range to develop and refine standards to a new level. The increased capacity compared to the FS-52 Surpass means more power/torque and the new carburettor provides even better throttle control across the entire RPM range! There are innovative features like incorporating the crankcase breather/oil recirculation system into the crankcase to dispense with external nipples and drain tubes as well as a dramatic & futuristic style. An effective and versatile silencer is supplied as standard.
