📌 Fitment Note: This Rear Cylinder Assembly fits all CFMoto 1000cc ATV, SSV, and UTV models listed above. Please carefully verify your specific model and engine code (2V91Y-X10/Z10/U10/C/D, etc.) before purchasing. If your model is not listed or you need to confirm piston size grade, please contact our customer service with your VIN.

⚙️ Product Functions
  • Forms Combustion Chamber Main Body: The cylinder body, together with the cylinder head and piston, forms the engine's combustion space.
  • Guides Piston Movement: Precision-machined cylinder bore provides accurate reciprocating guidance for the piston.
  • Heat Dissipation: Transfers combustion heat to the cooling system, maintaining normal engine operating temperature.
  • Ensures Sealing: Works with piston rings to seal the combustion chamber, preventing high-pressure gas from escaping into the crankcase.
  • Restores Engine Performance: Replacing worn cylinder and piston components effectively restores compression pressure, resolves oil burning issues, and improves power output.
✅ Fault Indications: Signs of cylinder/piston wear or damage may include:
• Engine burning oil, blue smoke from exhaust;
• Low cylinder compression, power loss, poor acceleration;
• Excessive blow-by from crankcase ventilation;
• Engine knocking noise (piston slap);
• Increased fuel consumption.
If you encounter these issues, check cylinder compression and replace the cylinder piston assembly if necessary.
✅ Installation Tip: When installing a new cylinder piston assembly, thoroughly clean the engine interior and replace all related gaskets. Pay attention to piston ring orientation and end gap positioning. Piston pin circlips must be fully seated in their grooves. Use specialized tools during assembly to avoid damaging the cylinder bore. Professional installation by an experienced technician is highly recommended.
⚠️ Important Notice: This product is a CFMoto Rear Cylinder Assembly Kit, containing all listed components. It fits the 1000cc ATV, SSV, and UTV models listed above. Minor variations (such as piston size grades) may exist between different model years or production batches. If your specific model is not listed, or if you need to confirm piston size grade, please contact our customer service with your VIN for compatibility verification. Images are for reference only; the actual product may vary.
🔧 Compatibility Notice
  • Please verify that this part fits your specific vehicle model and year. Many vehicles share similar names but use different components depending on year or market region.
  • We strongly recommend cross-checking with your vehicle's owner's manual or contacting us for confirmation before placing your order.
📄 Product Disclaimer
  • Product images, measurements, and descriptions are for reference only. Slight variations in color or appearance may occur due to manufacturing batches or photography lighting—functional specifications remain identical to the ordered part.
