Are you sure they are polypropylene?
Bob, first off thank you for advice you gave me a few months back about the ppg wash primer. Everytime I logged on here and replied it sent me a message back that your inbox was full.
Second, I'm not 100%, but I Googled the "zxmt" which is molded on the back and it came back with pp plastic fairings.

If it is PP on a motorcycle (new one on me) you treast the same way as TPO, TEO, PE, etc.

Alcohol based waterborne wax and grease removers are recommended for all new Toyota
bumpers by Toyota to eliminate future potential of peeling of paint. These products are a
must for new plastic bumpers as there are no mineral spirits in this product.
This product will also work great for fleet shops. This is a great pre-cleaning product for
interior parts and leather. Check a small hidden spot for any reaction first! Toyota has
finally admitted that there is a problem with paint sticking to new bumpers long term.
Their answer basically is this: Wash bumper with soap and water or a “scuffing paste”
type product with gray scuff pad, rinse and dry then wash bumper only with an Alcohol
Based Waterborne cleaner. At this point spray your adhesion promoter like SPI #600-4
on and according to Toyota your paint will never come off!
Yes, SPI’s Waterborne Wax & Grease Remover is an alcohol-based product. We suggest
you clean the bumper with our waterborne wax & grease remover 700-1, then scuff with
“Scuff Stuff” and clean again with the 700-1. Now spray your #600-4 Adhesion
promoter.

I googled "zxmt"and found they are a chinese manufacturer. My search came up with many sites all listing the fairings as made from compression molded ABS.
I would trim a spot and get a sliver or two of the plastic and put it in a glass of water. Rub it with water to get it wet , then immerse in the glass. If it floats then it is not abs and you need adpro.

ABS no adhesion promoter, lightly sand or scuff, shoot your epoxy let it flash half an hour and shoot the paint. ABS is easy to work with but it can bite you if you don't pay attention to cure times and solvents-it soaks up solvent. If there's minor cosmetic repair work to do on ABS I usually shoot a few coats of epoxy and let it cure for a good solvent barrier-do the repairs with polyester and finish it off with another application of epoxy for final sanding. The epoxy really helps the lifespan of this plastic IMO
