You don’t need to pay an exorbitant price for an exotic engine oil when Delo 400 SAE 40 will work just as well or better for $3.50 a quart.
And no, it won’t foam up like beer.

Maxima. Whichever fits your engine.
Plus the last time I've dealt with dirt bikes Honda still had separate engine and transmission oils, whereas everybody else was doing wet clutch with shared engine/transmission oil. My guess is Beta will be the latter.

Redline 40wt 50wt and the rest wt race oil from them I think they have 1200ppm moly
Don't know if the clutch will hold.
Also XPR from Royal Purple
Don't know if Elf lubricants produce on HTX series ones something that fit to your needs.

My suggestion is Castrol R. YES, I am joking. But nothing smells better. I remember going to the 12 hours of Sebring in the mid 1960's. I bullshitted my way into getting press passes which allowed me and my friend to get into the pits with my car and a rented camper trailer and right next to the track access, no barrier fence, a shuttle to wave down and move to a new location. Fond memories. LOTS of beer cans accumulating outside of our camper.
This was when the tradition breaking Chaparral was racing. American (highly modified) pushrod Chevrolet V8 coupled to...a (highly modified) two speed Powerglide transmission! If memory serves, as old farts often say, it never placed high, but it did better than many conventional power trains. It certainly made people sit up and take notice. Here we are almost sixty years later and no manual transmission hot car car can perform as well as our multispeed, paddle shifted cars. Back to the future!
Anyway, one could tell when a car was using Castrol R a few seconds after it passed. An auto geek perfume.
VR-1 Racing comes in 10w30, SAE 30, SAE 40 and O'Reilly carries all of these in stock
I have never looked on the bottle for the MA spec as I have only used it in cars and lawn mowers.
Tech changes over those 25 years, but it can also be very frustrating to sort through many old threads to try and come up with an answer. Sometimes it's just easier to ask.
I’ll vote for the mobil 1 15W50
It’s nice not having to worry about friction modifiers however just remember the more zinc and metals such as Molly in an oil can lead to piston deposits so it’s not all gravy to say something exceptionally high in those elements is better for the engine.
Mobil 1 certainly has a sufficient amount is my feeling.
In a poorly designed engine one with a subpar lubrication system then maybe something exceptionally high would help the engine. Just keep in mind. These additives are for areas of the engine that do not receive proper lubrication.
This. Oils from those two companies can take an absolute flogging and smile back at you! I have some used oil analysis from both on here out of my ninja 250.
