The online gear calculators tell me 4.77 ratio when I enter in the rpm/mph/tire size -- that can't possibly be right?!
Thanks!Andrew
I also have 4.10 rear and really enjoy not needing to down shift from 6th to 4th when doing 70 and want to pass someone.
Following picture is some more speed/RPM data to muddy the waters for you all...BEAST2 has seen 202 in 6th gear that I know of...maybe more that someone else knows of??
