Help identifying a part on my 2015 Gas Gas TXT Pro 125

After purchasing a 2015 Gas Gas TXT Pro Racing 125 I'm a little stumped with trying to figure out if what I'm looking at under the stator cover is factory part or something that's aftermarket. I've had some people say it's factory and other say it's an aftemarket flywheel weight (pictured below). The parts manual seems to be showing something that looks vaguely similar but I cannot confirm it and would prefer knowing if someone else has got a bike with a similar setup.

Hi jml

The fly wheel is a factory one, the diagram shows the extra disc for 125 cc bikes.
Contact Dave Ryan from Beta Racing on 03 5664 8368 for confirmation.

Confirmed on trialscentral.com that this is a factory flywheel weight.
