I have never seen this part, but here is my suggestion:
When I look at the parts book I see that part number 21 seems to consist of two parts; a sprag clutch (one-way bearing) and a ring that in some way holds this sprag clutch. My guess is that the sprag clutch is a industry standard part while the ring is made for GasGas.

Is the problem that the sprag clutch slips, and the starter does not rotate the crankshaft? In that case I would try to find the sprag clutch only. The ring can most likely be reused.
I don't have a part number for that sprag clutch, but if you extract it from the ring and do some measurements, I guess a well assorted local bearing supplier should be able to find someting in one of his SKF, FAG, INA or similar suppliers' catalog.

Or, if international on-line shpping is your thing, take a look here (after doing your measurements):
Simply bearings

For MFS450626550 the cheap fix could be this from a post i made a couple years ago:

I knew my starter clutch was slipping but even from ringspann it is quite expensive. I found a starter clutch with similar dimensions and teeth count on aliexpress. The part number for it is FWD331808BRB. Right now it is on ebay for ~8 EUR/USD. You will need to use your old starter clutch cage and put the teeth from this new starter clutch in there. The new spring is also a nice extra. The sprags are the same size and the amount is also correct. There are plenty of videos on youtube where you can see people rebuilding/replacing the spring on these and it was easy to make a working starter clutch. Just make sure the teeth go in the right way. In my case both the new and old starter clutch had arrows on them so it was easy.

FWD331808BRB bearing cage is different but the wear parts inside will work with your gas gas cage if it is not damaged. Just by replacing the metal "dogs" or "teeth" I was able to fix my starter clutch issues. This fix lasted me ~4 years and at that point the spring had become loose. With these 4 years some wear happened on the teeth too but replacing the spring made it work until winter. I already have a new FWD331808BRB waiting and I will do this exact process again before spring to make my starter clutch new again. This should be a really cheap alternative fix for MFS450626550.

in this video you can see the spring replacement but my fix takes it one step further and you replace the parts that are kept in place by the spring.
