The design and materials sounds expensive.   
I am impressed that the saw is capable of 12,500 rpm's.   That is a lot for a 4 stroke engine.

Sort of - but power specs was low and weigth very high for a 50cc chainsaw. Rather hopeless effort really.  ::)
It may be forced on us whether we like it or not. Yes the horsepower is low compared to a two stroke but what we have here is pure torque. The 2 stroke has to be screaming to produce, once speed drops off it dies. A 4 stroke will keep pulling, that 50cc will likely run 3/8 chain quite happily. Still, I am going to keep my 2 stroke as long as possible, I like the simplicity and light weight.
