I'll kick in with a comment on this. I considered the baker, however with the extra cost of the baker, and the fact a buddy of mine had to send his back due to a major problem with it (which baker covered totally) I went with the Harley 6 speed. I do lots of road miles and figured if I had a problem, at least it's Dealer supported.
I went with the 3:37 gearing set up along with the 6 speed box which I swapped out.
After putting 1400 miles on this set up in Daytona all i can say is, it made a great choice for me personally. Extra zip from 1st thru 5th, crusing in 6th is a breeze and I did not notice any problem at speeds lower than 70 in 6th. 70 and above, just add right wrist and it moves right along.
Now if you swap out the total gearbox, it is an added expense for sure, but I figured if I want to re-coup some of the cost, I can always sell the complete 5 speed in the future. The 5 speed gear sets do not seem to be a big money maker on e-bay.
Now all I need to do is stop trying to find that 7th gear,,lolololol
