Grom JC92 can't be used as it is, but I was able to get the Piston Pin out with ease.
Piston Pin Puller, very useful.
I bought it because it was listed as having a compatible Piston Pin Size of 12mm to 25mm, but I need to take a moment to pull out the 12mm Piston Pin of the Grom JC92.
The construction of the product is very good, the grips are anodized, and it is not cheap.
Four types of attachments are included for pulling out the Piston Pin, which may be used on Large Motorcycle.
In the case of the Grom JC92 Piston, the smallest attachment has an outside diameter of more than 12mm, so the attachment is caught on the Piston perimeter and does not reach the Piston Pin.
So I pulled it out by biting a Spacer with an outside diameter of less than 12mm and about 5 cm, as shown in the photo.
The Curve on the Piston contact side of the Grip section was also fit to the Piston.
The Piston ring acted as a good buffer to prevent damage to the Piston, so there was no need to protect it with Dustclothetc.

Piston Pin lightly escapes!
Used to remove Piston Pin of RZ 250 R. Pin was punched and it was not easy to get out, so purchase this product. After setting Puller, just by turning it in Wrench, Sulur and Piston Pin are missing. Although the difficulty can be used for each Size, on the other hand, I think that it is better for you to have Rubber sheet because Puller's surface will not be Fit and Piston will be scratched.
It was good that I could buy it because I got out of it without difficulty.
