The WISECO Piston Kit is designed for select Kawasaki KX500 applications and features an 86.00 mm piston size. Forged from high-silicon aluminum alloy, the piston is engineered for strength, dependability, durability and sustained performance in trail and racing applications.
The kit features a forged piston, rings, wrist pin and circlips. Its forging design and piston skirt are intended to support increased horsepower and torque, while the high-tech piston design offers high compression ratios and an ultra-stiff structure. Titanium nitride-coated rings contribute to sustained power, and E-Coating on the crown, ring grooves and pin bore helps provide wear resistance and protection against micro-welding, galling and detonation.
GP Series construction generally uses less machining on the outside to help seal the bore for increased compression. Boost ports are removed for a more predictable powerband and increased pull on the top end. Cylinder sleeves must be purchased separately. Racer's Choice pistons are intended for expert racers and tuners only and may allow increased service intervals compared with conventional WISECO pistons. Distributor part number: 575M08600. Manufacturer part number: 575M08600. Fits 1990, 1991, 1992, 1993, 1994, 1995, 1997, 2000, 2001 and 2004 Kawasaki KX500 models.
