Zoom zoom piston?

[wildyz250]

I acquired this piston in a parts lot, it says zoom zoom on the top. Can anyone tell me what the compression is as it looks comparable to my wiseco 12:1 as well as my j.e 12:1. Also are they a good product.thabks in advance!

Zoom zoom forged pistons are 85mm 12:1

How do they compare to the wiseco and say j.e?

They're fine but wiseco and je are still going to be higher quality.
