If you (Kyle) and FortNine get it, you have obfuscated with self esteem. It was not that long ago when all Harleys had solid mounted engines and no counterbalance shafts. (and two valves/cylinder) Your handling analysis is not entirely correct, but you would not believe me anyway. The sound issue is more objective.
Despite the numbers expressed, Harley riders are still a vocal minority. I would be OK with that if they kept it to themselves. Unfortunately the demographic demands everyone must hear the noise; "hear me, see me, aren't I grand". That is not welcome in my rustic rural environment, or when I visit other rustic environments. I endure the noise at home when it is 1-2 miles distant. Objectively that means 50-300 other pairs of ears "per mile" also experience "disturbing the peace".
You misrepresent the means of producing that noise:
It's 2-1, front cylinder fires, 315 degrees later rear cylinder fires, 405 degrees later front cylinder fires. The rear cylinder is cylinder #1. That's what HD puts in their training manuals.
There were flat trackers made to fire 45° apart (called 'twingles') but all production bikes fire as above. Why a twingle? It makes the rear tire hook up better on one mile clay tracks where the sound is appreciated.
