This looks great O.S.!!! Finally some new technology for 2 strokes.

This is the second AX Series engine after 46AX.
Standard silencer is compact and easily enclosed in most cowls. Also, Extension adaptor and 90 degree adaptor offers several silencer installations.
Specifications: MAX-120AX RING
It is a torquer like the 1.6FX....usable rpm is only up to 9,500--small transfer ports(& case size).
If it is really only 21oz plus muffler that means with a good turbo jet it will be 28oz--same weight as YS110 and will beat it in power!!!!
2 strokes are back on top baby!!!
Notice no remote glow.
