Rumors are rumors but, never say never.
Honda was against 2 strokes once before, before they brought a dominating CR250 Elsinore out.
Honda is a corporation, corporations are in business to make money.
When it makes business sense to bring 2 strokes out, they will again.
Meanwhile, I'll keep riding all my 2 strokes while others are rebuilding valve trains.
Don't get me wrong, I don't hate the 4 strokes.
I love the technology.
What I hate is, there is no choice.
On a side note, I can tell you first hand that the Honda service personnel do not like to work on the new engines.
