Wiseco Forged Piston - Kawasaki 1500 NA - SX-R STX Ultra

Wiseco's forged piston kit is engineered and machined in the USA from high-strength 2618 aluminum for superior durability and performance. This kit includes everything you need: pistons with skirt coating for reduced friction, premium piston rings, wrist pins, and circlips. These pistons feature dedicated forgings that optimize the strength-to-weight ratio, delivering improved tensile strength, enhanced service life, and proven reliability across all riding levels. They excel in withstanding the high demands of both supercharged and naturally aspirated applications.

For supercharged watercraft variants, which experience extreme loads even in stock configurations due to boosted pressures and higher combustion forces, Wiseco pistons provide the robust construction needed to handle these stresses without compromise. Whether you're rebuilding after a failure or planning heavy modifications like increased boost or rpm, upgrading to these forged pistons is a no-brainer— offering greater strength to prevent future issues when trying to make more power.

In naturally aspirated applications, Wiseco's forged design is lighter than traditional stock cast pistons, contributing to quicker engine response, smoother revving, and overall improved throttle feel for a more engaging ride. Backed by Wiseco's reputation for quality, this kit ensures your engine performs at its best under any conditions.
