high compression piston kit featuring a 14mm wrist pin works with
SDG 125
RCM 125
Sikk MX 120
Lifan 120
Zongshen 120
This piston kit feature valve reliefs big enough to handle the "Monster 120 Lifan head." The kit will also work with high lift/duration race cams!
Our piston kit is good for a compression ratio of 12.5:1, with a 10% gain in power by installing it in place of your low 9:1 stock compression ratio!
This is a drop in replacement piston, no boring required
