Description
When your 2-stroke engine demands a fresh top-end, settling for OEM parts leaves performance on the table. The Wiseco PK1639 delivers a complete piston kit engineered from aerospace-grade 4032 aluminum alloy, purpose-built to handle the extreme heat and RPMs of competitive riding. This is a bolt-on refresh that restores—and exceeds—factory specifications without fabrication work.
Whether you're prepping for the gate or logging trail hours, this kit eliminates the guesswork of sourcing individual components. Wiseco's forged Pro-Lite piston design reduces reciprocating mass while maintaining the durability required for sustained high-RPM operation. You get improved throttle response, sharper torque delivery, and the confidence that every piece in the assembly meets racing-grade tolerances.
