This is one of the worst sections of the 4.25 miles of "Ho Chi Minh Driveway"

If it's dry, it's ok, just not the most pleasant Brickin' you've done. My K75 handles it with aplomb daily.
If it's wet, FERGETABAHTIT!! Wet periods are when this goat path earned the name "Road of Woe" in our neigborhood vernacular. You would not be able to progress one inch before you and bike would be sideways and down. It's a very
special kind of mud, of the sort you'd find in a special corner of motorcyclist's hell. Days like that I drive the 4runner. Even my enduro can't remain upright on dat chit.
So make sure you drop me a note and enquire about conditions - during crappy periods I have friends with whom yer ride can be left with in town, and we'll pick you up in 4wd transport.
The good news is that after most summer showers the road dries within a matter of hours, or at most in a day or so.
