Review WISECO Powersports Piston M06640 fits KX250

The WISCO 844M06640 piston, with part number M06640, is a high-performance replacement piston designed specifically for the Kawasaki KX250F and FT05 motorcycles. This piston is manufactured by WISCO, a leading aftermarket manufacturer known for producing precision-engineered components that deliver superior performance and reliability.

This piston features a forged construction made of high-strength aluminum alloy. Forged pistons provide greater strength and durability compared to cast pistons, ensuring the piston can withstand the demands of high-performance riding. The piston is also designed with a compression height of 25.6mm, making it an ideal upgrade for riders seeking increased power and torque from their engines.

The piston crown is CNC machined to ensure a perfect fit and finish. The crown features a dish design, which helps to reduce piston weight while maintaining strength. The piston also comes with a ring package that includes a compression ring, oil control ring, and two skirt rings. These rings are designed to provide optimal sealing and engine performance.

Additionally, the piston skirt is designed with a full-length, split ring groove, which allows for the use of aftermarket piston rings with split ring clips. This provides riders with more flexibility when it comes to choosing aftermarket rings that may offer improved performance or durability.

The WISCO 844M06640 piston is also coated with a thermal coating. This coating helps to reduce piston-to-cylinder friction, which in turn helps to reduce engine heat and improve overall engine efficiency.

In summary, the WISCO 844M06640 piston is a high-performance replacement piston designed specifically for the Kawasaki KX250F and FT05 motorcycles. Its forged construction, CNC-machined piston crown, and thermal coating make it a reliable and effective upgrade for riders seeking increased power, torque, and engine efficiency.
