I am looking for replacement big bore pistons for an ATC 110 I have tried both Powroll and Wiseco who stat they don't carry anything.

However XR100 54.5 mm piston has the same bore I need and the wrist pin diameter (15mm) and piston deck height (.510) are the same. Is there any reason i can't use this piston as a replacement?

any help will be greatly appreciated
