The WISECO RE831M07800 piston kit is engineered to deliver proven power gains for Kawasaki KX250 models, featuring a 97.00 mm diameter piston designed for high performance. Crafted with precision, this kit includes a dome-shaped piston that enhances flame travel for better air/fuel combustion, resulting in increased torque and throttle response. Made entirely from 100% billet machined aluminum, the piston offers a superior strength-to-weight ratio that ensures durability and optimal performance under demanding conditions. The high compression ratio of 14:1 for 450cc and 14.5:1 for 250cc engines maximizes power output, making it ideal for competitive riding or aggressive trail use. The piston's asymmetric skirt design improves wear characteristics and ensures even loading on the major thrust skirt, reducing uneven wear and extending component life. The custom-lapped compression ring and pressure seal groove enhance sealing efficiency, reducing power loss and maintaining consistent compression levels. The piston also features a DLC-coated piston pin that minimizes friction and enhances scuff resistance, paired with enhanced pin oiling for superior lubrication and durability. ArmorGlide® skirt coating further reduces friction, contributing to quieter operation and improved scuff resistance. Designed and manufactured in the USA, the WISECO piston kit includes rings, pin, and circlips, providing a comprehensive upgrade for your Kawasaki KX250 engine for maximum horsepower and reliability.
