I agree J Mac.  It’s cool that I was researching and pondering the same topic as some folks 15 years ago.  More than once I’ve posted a “new” question that’s been asked/answered/debated and beaten to death many moons ago.  I found this post and resurrected it instead.  I was actually more interested in maximum speed by gear.  That’s kinda a bad question though because redlining a gear is one thing (not necessary or ideal), and optimal shift point for best 1/4 mile time is another thing.  And you’d have to preface the question with “stock” or a certain set of modifications to get a useful answer.  And the stock bike doesn’t have a tach, so a lot of answers would be stated in MPH.
