2019 PCX (2100 miles) Rattling noise when throttle is just maintaining speed

[Fedner]

This PCX is new to me, and I've never ridden any other PCX, so I don't know if this is normal or not. People say that the PCX has a "noisy transmission", so obviously I'm hoping this is normal.

The 2019 PCX is 100% stock, and I'm in the United States.

== The Issue ==
Everything works just fine on the scooter. Acceleration is excellent and smooth. But I notice that when I roll off the throttle to maintain speed, usually around 25mph to 35mph... the rattling begins. Any change in throttle position makes it go away. It only does it when the throttle is stationary. I think it sounds more apparent on the left side of the bike.. It's not super loud, but I'm pretty sure that bystanders on the side of the road would be able to hear it. It is very difficult to discern what it is, as it could just be a mildly annoying exhaust note, for all I know. Normal? Or not?

I ordered a new drive belt just in case. When that arrives, I'll open the drive belt are cover and take a look inside.

something loose in the exhaust chamber? Take it off and shake it.
