The engine outer shell adopts high-strength die-cast aluminum alloy, featuring lightweight, high rigidity and impact resistance, effectively resisting external collision, dust and mud erosion in off-road environments. The cylinder block is equipped with a thickened high-precision cast iron liner with high-temperature oxidation and wear-resistant treatment, avoiding cylinder pulling and abrasion during long-term high-load operation. Forged alloy steel crankshaft and connecting rod undergo professional dynamic balancing calibration to ensure stable operation without jitter. The heat-resistant hypereutectic aluminum alloy piston prevents high-temperature deformation and improves fuel combustion efficiency. The precision-machined valve train and camshaft ensure accurate intake and exhaust, fully releasing engine torque. The matched professional liquid cooling circulation system achieves rapid and uniform heat dissipation, completely solving the overheating problem of old-generation CF ATV engines during continuous work.

Fully Compatible Models:

1. CFMOTO CF500 ATV: Exclusive fit for 2011, 2012, 2013 factory models
2. CFMOTO CF600 ATV: Exclusive fit for 2011-2013 full trim level models

Fitment Advantage: Strictly manufactured according to 2011-2013 OEM original standards, 100% consistent with original mounting holes, wiring harness interfaces, water and fuel pipeline positions. Realizes plug-and-play direct replacement without drilling, cutting or wiring modification. Perfectly matches the original ATV frame, transmission system, electrical components and exhaust assembly with ultra-high fitting accuracy and zero installation barriers.

All ATV engines are produced in ISO9001-certified standardized factories with strict production process supervision. Each finished engine undergoes multi-dimensional strict pre-shipment tests, including cylinder compression test, liquid cooling system leakage test, fuel system sealing test, idle stability test and high-load continuous operation test, ensuring no oil/water leakage, sensitive startup and stable power output. We provide 6-month professional quality warranty service. All non-human-induced quality failures support free replacement and one-on-one professional technical guidance, enabling global dealers and individual off-road enthusiasts to purchase with full confidence.

Adopts professional export-grade multi-layer protective packaging: internal anti-rust oil coating, waterproof and moisture-proof plastic film wrapping, high-density foam anti-collision protection, and external reinforced solid wooden box packaging to prevent extrusion, collision and moisture damage during long-distance international transportation. The gross weight of a single engine is about 40kg with standard export packaging dimensions. It supports global shipping methods including sea freight, air freight and international express, suitable for retail and bulk wholesale export to Europe, North America, Australia, Southeast Asia and global ATV parts markets.

Professional mechanical installation is recommended to ensure assembly accuracy and off-road driving safety. Replace brand-new supporting gaskets and oil seals during installation to enhance engine tightness and prevent oil and water leakage. After installation, inject 10W-40 dedicated 4-stroke ATV engine oil and fully inspect the tightness of fuel pipeline, water circuit and wiring harness. New engines require a 500km break-in period; avoid long-time full-load climbing and heavy-load towing during the break-in period. After break-in, replace the engine oil and clean the filter element to optimize engine power and stability. Regularly check the cooling liquid level and clean the heat dissipation system to ensure stable liquid cooling effect and extend engine service life.

Ideal for personal CF500/CF600 ATV engine replacement and repair, professional off-road vehicle maintenance shop spare parts supply, engineering vehicle bulk procurement, ATV power upgrade modification, and global powersports parts wholesale business. Widely applicable to farm traction, field hunting, mountain cross-country, outdoor engineering operation and daily leisure off-road riding, it is the most reliable OEM replacement part for 2011-2013 CFMOTO 500/600 ATV owners.
