That 70cc NGH engine is interesting. I can see it being a substitute for using a 50cc two stroke engine. I guess they are using some imagination and creativity as I don't see OS as having ever made a engine with anything using upper end parts at around 70cc in size before. So they had to scale up the design to 70cc then.

The OS engine does look pretty good too.
