The engine shell is made of high-strength lightweight die-cast aluminum alloy, featuring high rigidity, impact resistance and deformation resistance, which can effectively resist daily riding vibration and external scratches. The thickened precision cast iron cylinder barrel adopts high-temperature and wear-resistant treatment, avoiding cylinder wear and power drop during long-term frequent acceleration. The dynamically balanced crankshaft and connecting rod ensure stable engine operation without jitter. Optimized piston and intake/exhaust structure improves combustion efficiency and power explosiveness. Integrated dense heat dissipation rib structure accelerates air circulation, ensuring stable heat dissipation and continuous power output during long-hour daily commuting.

• Universal fit for all Yamaha JOG50 2-stroke scooters, full year models

Fitment Advantage: Manufactured strictly in accordance with OEM original standards. All mounting holes, wiring interfaces and oil pipeline positions are 100% consistent with original vehicles. Plug-and-play direct replacement, no drilling, cutting or modification required. Perfectly matches the original JOG50 frame, CVT transmission, electrical system and exhaust assembly with ultra-high fitting accuracy.

Produced in ISO9001 standardized factory with strict production process supervision. Each finished engine undergoes multi-dimensional pre-shipment tests including compression test, oil sealing test, idle stability test and continuous load operation test, ensuring no oil leakage, sensitive startup, stable power and zero abnormal noise. 6-month professional quality warranty is provided. Non-human damaged quality issues support free replacement and one-on-one professional technical after-sales service for global dealers and individual users.

Adopts export-grade multi-layer protective packaging: internal anti-rust oil treatment, waterproof film wrapping, high-density foam shockproof padding and external reinforced wooden box packaging. Effectively avoids collision, extrusion and moisture damage during long-distance international transportation. Supports sea freight, air freight and international express, suitable for global retail and bulk wholesale business.

Professional mechanic installation is recommended. Replace brand-new gaskets and oil seals during installation to prevent air and oil leakage. Strictly use standard proportion 2-stroke mixed fuel. Check the tightness of carburetor and oil pipeline after assembly. New engine requires a standard break-in period; avoid long-time full-throttle high-speed riding. Regularly replace 2T mixed oil and clean the air filter to maintain stable power output and extend engine service life.
