Description
Your KX80’s performance ceiling is limited by factory piston specs—worn or inadequate pistons rob horsepower, increase blow-by, and accelerate engine wear. The Wiseco PK1301 delivers OEM-plus reliability with measurable gains in throttle response and sustained RPM stability. Whether you’re prepping for competition or maximizing trail performance, this complete kit eliminates guesswork and delivers bolt-together convenience.
What sets the PK1301 apart is Wiseco’s forged aluminum construction and CNC-refined geometry. You get a piston engineered to handle sustained high-RPM loads without sacrificing durability in harsh riding conditions. The included rings, wrist pin, circlips, and gaskets mean you’re not hunting down complementary parts—everything needed for a clean, professional rebuild is in the box.
