Wiseco Piston Kit 48.50 mm for Kawasaki KX 80 1988-2000 644M04850

Stock pistons can't handle the demands of extended trail riding or track time—especially in a high-revving two-stroke like the KX 80. This Wiseco piston kit delivers the durability and compression optimization your engine needs to maintain peak performance across service intervals, whether you're pushing hard at the track or putting in serious saddle time on technical terrain.

The high-silicon aluminum forging resists thermal stress and detonation, while the E-coated crown and ring grooves extend component life in aggressive riding conditions. You're getting a complete, ready-to-install solution: piston, rings, wrist pins, and circlips all engineered to work as one system.
