If you liked the 46FX, you're gonna love the 46AX! ORIGINAL Japanese
As the replacement for the high-performance 46FX, it's no wonder that the .46 AX shares many of its features. The raw power. A remote needle valve. Mounting bolt patterns. A balanced "D"-cut crankshaft supported by dual bearings. CNC-machining for the piston and other parts. And the same exclusive ABL cylinder liner that has made FX reliability a byword. But all the same, the 46AX is a different – and better – engine. Why? Because times change and technology advances. And because O.S. uses the best of both to make a good engine a better engine.
