Wiseco Kawasaki KX450F Piston Set - Kawasaki KX450F 09-12 12.51 CR 9600ZV is a forged piston kit built for 2009–2012 KX450F models. It provides a direct-fit replacement matching the 96.00 mm bore and the kit designation for a 12.5:1 compression ratio (listed as 12.51 CR in the part ID).

Manufactured and machined in Mentor, OH, Wiseco's forged 4-stroke pistons are engineered for specific engine applications and produced to tight tolerances. This kit includes high-quality piston rings, wrist pin(s), and circlips, and uses dedicated forgings to optimize strength-to-weight characteristics and improve tensile strength over typical cast components. Intended as a stock-dimension (standard bore) replacement, the piston is suitable for rebuilds and performance-minded maintenance where durability and precise fitment matter.
