⚙️ Product Features
  • Complete Kit: Includes piston, rings, wrist pin, and circlips – everything needed for a full piston replacement.
  • OEM Specifications: All components manufactured to meet or exceed original equipment standards.
  • Precision Machined: Piston diameter 57mm with precise clearances for optimal engine performance.
  • High-Quality Materials: Piston made from durable aluminum alloy, rings from wear-resistant cast iron.
  • Restores Compression: New piston and rings restore cylinder compression, improving power and fuel efficiency.
  • Reduces Oil Consumption: Properly sealed combustion chamber minimizes oil bypass and consumption.

🛑 When to Replace Your Piston Assembly

A worn piston or piston rings can cause blue exhaust smoke (oil burning), loss of power, hard starting, and increased fuel consumption. If you're experiencing these symptoms, or if you're rebuilding your top end, replacing the complete piston assembly ensures all components are fresh and matched. This kit provides everything needed for a professional-grade rebuild.

⚠️ Installation Hint: Piston installation requires careful attention to ring gap orientation, proper lubrication, and use of a piston ring compressor. Always install new circlips securely and ensure they are fully seated in their grooves. If you are not experienced with engine assembly, professional installation is strongly recommended.
🔧 Compatibility Notice
