I can see that the 85 will make more power, but will it be that much!
They will hike the price a little I guess, and why not. In some ways they keep tooling costs down this way ( small developments) and they do pass the savings on to us. Its reflected in the cost.
Personally I like the 3W motors I have had, my 80 has been very good to me
I have not need service yet, hope that will be as good as ZDZ was to me!
