Description
The CP Carrillo M4069-13.5 represents the bleeding edge of Kawasaki STX-15F/SX-R racing piston technology with its extreme 13.5 to 1 compression ratio. Compatible with all 83mm bore Kawasaki 15F/SXR1500 engines, this ultra forged kit demands championship level tuning but delivers mind bending naturally aspirated power. CNC machined from premium heat treated billet, these pistons push the absolute limits of marine compression ratios while maintaining the strength needed for redline destruction.
Every detail of the M4069-13.5 is optimized for maximum combustion pressure and efficiency. Specially contoured domes, ultra precise ring grooves, and featherweight skirts work together to extract every possible horsepower from race fueled 1500cc engines. The lightweight forged construction allows unprecedented RPM capability while race proven coatings protect against the brutal heat of extreme compression ratios.
- Universal fit All Kawasaki STX-15F/SX-R 1500cc platforms with 83mm standard bore.
- Insane 13.5 to 1 compression requires championship level race fuel and ECU calibration.
- Race specific ring packages minimize friction while maximizing cylinder pressure.
- Featherweight design unlocks RPM potential beyond factory engineering limits.
- The choice of top Kawasaki racers chasing naturally aspirated world records.
Ultra-premium forged billet with specialized heat treatment and coatings for extreme duty.
When only victory will do, Kawasaki racers choose the CP Carrillo M4069-13.5 13.5:1 ultra racing piston kit. This is engineering at the absolute limit – where precision forging, championship tuning, and race fuel create personal watercraft history.
