⚙️ Features & Performance Benefits

Complete Kit + Linhai Compatibility: Includes piston, piston pin, and circlips with both CFMoto and Linhai part numbers for precise cross-platform fitment.
Direct OEM Replacement: Perfectly matches CFMoto original part numbers and Linhai 1BE series numbers for accurate installation dimensions.
Precision Cast High Performance: Manufactured from high-quality aluminum alloy with special skirt coating to reduce friction, improve wear resistance and heat load capacity, significantly enhancing engine response and compression stability.
Balanced Weight Reduces Vibration: Precise piston weight control ensures engine balance, reduces vibration, and extends crankshaft and connecting rod life.
Proper Installation Direction: Piston top features orientation marks that must face the exhaust side of the cylinder, ensuring proper piston ring operation and avoiding interference.

✅ Importance of Piston Replacement: The piston is one of the most critical components in an engine, enduring high-temperature, high-pressure combustion forces. After prolonged use, piston ring grooves may wear and the piston skirt may show scoring or wear, leading to reduced compression pressure, increased oil consumption, power loss, and hard starting. Severe cases may result in piston seizure or fracture, causing major engine damage. During engine overhaul, replacing the piston and piston rings is standard procedure to restore engine performance.

🔧 Installation Guide

Preparation: Thoroughly clean the cylinder and piston installation area. Inspect cylinder walls for scoring or excessive wear. It is recommended to replace piston rings (sold separately) simultaneously.
Orientation Confirmation: The piston top typically has "IN" markings or arrows that must face the engine exhaust side (exhaust pipe direction). Incorrect installation can cause piston-to-valve contact or piston ring damage.
Piston Pin Installation: Apply a small amount of engine oil to the pin surface before installation. Use a special tool to press it in, avoiding impact that could cause deformation. Circlips must be fully seated in the groove with the opening not aligned with the piston pin bore notch.
Clearance Check: After assembly, check piston-to-cylinder clearance (standard 0.03-0.05mm) to ensure smooth piston movement without binding.
Torque Requirements: Connecting rod bolts must be tightened in steps using a torque wrench to factory specifications (typically 35-40N·m) with thread locker applied.
Break-in Procedure: After installing a new piston, perform a 300km gentle break-in period, avoiding full-throttle operation. Change engine oil and filter after break-in.

⚠️ Verify Before Ordering: Please ensure your vehicle and engine model are listed in the compatibility chart and verify that the piston diameter (88mm) matches your original. During installation, ensure the piston top marking faces the cylinder exhaust side and use new piston rings. Professional mechanic installation is recommended, along with measuring cylinder wear and performing boring or cylinder replacement if necessary.
