Wiseco High-Compression Piston Kit, 78.00 mm for Kawasaki KX250/X (RE828M07800)

Developed by Wiseco through research and dyno testing, the RE828M07800 piston kit is designed to deliver responsive power, strong torque, and reliable performance for compatible Kawasaki KX250/X applications. Its high-compression design is engineered to improve throttle response and maximize air and fuel burn efficiency, while the optimized dome shape promotes efficient flame travel throughout the combustion chamber. This piston is precision manufactured from billet material for an excellent strength-to-weight ratio and a consistent, application-specific fit.
The asymmetric skirt design helps promote even loading across the major thrust surface, improving wear characteristics during demanding riding conditions. An ArmorGlide® skirt coating reduces friction, supports quieter operation, and enhances scuff resistance. The DLC-coated piston pin further reduces friction and helps resist scuffing, while enhanced pin oiling improves lubrication for dependable operation. A pressure seal groove helps minimize ring lifting and reduce power loss under high-performance conditions.
The Wiseco RE828M07800 piston kit includes the piston, rings, piston pin, and circlips for a complete installation package. Its custom-lapped compression ring is precision fitted to support improved sealing and power delivery. Made in the USA, this high-performance replacement kit is built for riders and builders seeking durable components, efficient combustion, and strong engine response in compatible Kawasaki KX250/X engines.
