Ultra is marketed as "Racing" oil, and Extra as a "Performance" oil. Ultra has unconventional weights, and an additional ester that Extra does not. Otherwise, they are identical. This particular ester is very "slick" (and presumably expensive), and gives the oil increased performance.

The absolute only place where you can use HP4M with Moly, is in the engine (not transmission) of the TRX450R or CRF dirt bikes. This oil is JASO MB, and has absolutely no other application! It cannot be used in anything with a integrated engine and transmission oil (your 400EX). These require an oil that is JASO MA.
Like I said before, HP4 use to be API SG, which is widely accepted as the last descent oil grade (reasonable amounts of zinc, etc.). And, for years that is what it was. But now, it is API SJ, which is some watered down car oil standard. So, like I said, I no longer use HP4. I recently noticed that Yamaha's oils are also API SJ. There are a bunch of excellent API SG oils out there, find yourself one of those!
