Description
A piston assembly is the heart of your engine’s combustion cycle—when it wears, power fades and reliability suffers. The WSM Piston Assembly for Kawasaki 12F delivers OEM-equivalent quality with measurable upgrades: a MOS2-coated skirt that actively dissipates heat while reducing friction, plus specially hardened ring grooves that resist the stress of high-RPM operation. This is a direct replacement engineered to restore performance and extend engine life.
Order one assembly per cylinder. Each includes the piston, compression and oil-control rings, wrist pin, and improved E-clips—everything you need for a complete refresh. Additional ring sets are available separately if you’re replacing multiple cylinders or building a long-block.
