I think they went with the 4 speed in the new YZ to allow for wider, stronger gear wheels.

This is not an oem thing, just something I learned building turbo GS-1100's a few years back.
A good motorcycle transmission shop can help you build a bullet proof 5sp.
I have had excellent results from R&D.
They don't have a web site but here is their #.
