This is a genuine Vito's Performance product
These are FORGED aluminum pistons for ATHENA cylinders
Forged! just like Wiseco, not the cheaper CAST ones seen online for a few dollar cheaper
Designed for a BIG BORE stock height cylinder
Set up with proper pin height for a 4mm short rod 110mm stroker crank
These have 9 degree dome angle
The intake windows have been raised and enlarged
The intake windows have a 50% thicker bridge - makes them last much longer than Wiseco thin ones
Includes RIK 1mm thick rings - more tension and life than any other ring currently on the market (regular Wiseco 68mm rings will also fit these)
2mm offset pin location - no spacer plate needed!
