It looks like Jim's USA is who is making the new six speed transmission for HD. HD has a performance upgrade six speed listed for the factory six speed bikes.

I hope they've addressed the loose shift drum that allows shift forks to be loose when each gear is engaged. 

It looks to be a direct compete with the Baker Grudgebox.
