Are you surprised there's any moly in both of the ST motorcycle samples?
Nope.
Then what really makes JASO MA2? I'm not seeing anything earth shattering for wet clutch, what am I missing?
JASO MA2 standard is not very stringent at all. Its only real value is the friction test for wet clutches. Most modern oil would pass the test moly or not.
That being said, I would not try toyota factory fill oil in a wet clutch with its 200 ppm of moly.

Thx been wondering about this one
You folks are very welcome. Waiting on the Providence HD 30 HDEO sample to show up
I stashed some a few years ago from a sale. I'm going to use this on the next oil change in the ZRX 1200. Impressed with the makeup of this oil. M1 10w40 4T and 20w50 Vtwin have much higher moly and boron but otherwise the ST oils are somewhat similar in additive packages.
Moly ????????
less than 200 ppm of moly is nothing, non issue. Esepcially below 100 ppm, not even worth talking about.
now you get 400 - 700 ppm, now you are bordering to have clutch issues.

Pulled the trigger and this oil is in the ZRX1200 sump as of today. Looking forward to giving it the usual 5,000 mile OCI. Won't get there on miles til next riding season, though.
