Kawasaki KX450F Piston Set - Wiseco - 12.5:1 CR, 96mm Bore ('13-'18). This Wiseco forged piston kit is built for riders and mechanics upgrading or refreshing a KX450F engine from 2013–2018, offering factory-fit dimensions and components for a complete install.

Designed and manufactured by Wiseco in the USA, this 96.00 mm bore piston set features a 12.5:1 compression ratio and is a dedicated forging for the KX450F application. The kit is forged and machined to tight tolerances to provide consistent ring sealing and durability under typical motocross and off-road use. Included hardware and rings simplify rebuilds and reduce parts sourcing time, while the optimized forging improves tensile strength compared with cast pistons.
