This particular set weighs 327g. It can be lightened substantially with 3d undercrown CNC milling. As is though, it weighs less than a stock 86mm piston ~335g.
This same piston will net the following static compression ratios for each displacement:
12.28:1
90mm x 86mm = 2188cc
12.54:1
90mm x 88mm = 2239cc
12.898:1
90mm x 90.7mm = 2308cc
13.2:1
90mm x 93mm = 2367cc
13.987:1
90mm x 99mm = 2519cc
