With respect, I think the chart in your manual has a typo. The portion you highlighted says "
or JASO-MA2", whereas the chart in the manual for my 2017 says "
and JASO-MA2". The same engine is involved so there's should be no difference.
It's well known that JASO-MA is a spec for wet clutches. In my manual's text regarding engine oil there is also specific note to only use oils designed for wet clutches (ie without friction modifiers) and to not use oil additives. Interestingly, the text also says that regular JASO-MA oil is an acceptable alternative to JASO-MA2 oil. From what I read the MA2 grade is designed for engines with CAT converters... but I have no idea what difference that should make.

After speaking with an oil company technical guy here in Australia a while back, I think I can explain why your Quaker State 5w-40 Synth & Pennzoil Euro Full Synth 5w-40 hasn't caused any clutch problems yet, even though it doesn't mention JASO-MA on the label.
Both of those oils mention compliance to ACEA-B4. According to the technical expert "ACEA-B4 is the Euro. Light Duty Diesel oil spec. These oils have higher levels of detergents and dispersants, and this is one of the reasons that they have such good frictional characteristics, which is important for wet clutch operation. In fact, the chemistry used is able to be approved against JASO-MA.". He goes on to say that even though their ACEA-B4 oil 
should theoretically be able to be certified to JASO-MA, they haven't gone down the path of gaining formal approval from JASO as the cost involved isn't warranted against the expected volume of motorcycle market sales.
So, maybe the Quaker State & Pennzoil is in the same boat... 
technically able to be certified to JASO-MA, but the oil companies have decided paying for approval isn't warranted. But please don't just take my word for it. My advice would be to contact a technical expert from your preferred oil supplier & get their sign-off on its use in your Spyder.
Hope this helps!
