I love a crossplane engine, they just sound dirty and purely unadulterated. A flatplane engine does sound beautiful but sounds beautiful in a symphonic way.
The Yamaha R1 sounds more like a Ducati than your atypical Japanese inline 4 screamer. I see and hear a 2010 R1 with a full Akrapovic system quite often and it sounds sublime.
I'd just like to be the first to say, on behalf of the entire forums, i am SO SORRY about that terrible farming machinery accident that ripped off both of your ears and rendered you completely deaf.
