The third engine in the new ‘AX’ range of high performance 2 stroke engines fills a convenient gap between the existing 61FX and 91FX, yet features the radical new style pioneered with the fabulous 55AX. The new 75AX is supplied complete with the latest ‘P-Box’ design silencer for improved noise suppression. By keeping the lower crankcase dimensions the same as the 61FX, you can be sure that it will fit in all models designed for a .61, making a power upgrade very simple. The 75AX features the latest O.S. ringless piston technology with multi-layer cylinder coating and high precision Type 61A carburettor with angled safety needle valve assembly.
