Key Performance&Design Features

Efficient Air-cooling System

Large-surface area,densely structured cooling fins provide superior heat dissipation,ensuring stable operation under continuous loads.No coolant maintenance,leak-proof,and highly adaptable to harsh,remote working environments.

Strong Low-RPM Torque

Tuned for optimal torque output at mid-low RPM,delivering strong pulling power,smooth hill-climbing,and consistent performance when fully loaded—perfect for tricycle cargo hauling.

Enhanced Durability

Forged steel crankshaft,hardened valves,and wear-resistant piston rings extend service life.Enlarged oil passages and upgraded oil pump ensure reliable lubrication,reducing component wear.

Built-in Balance Shaft

Integrated balance shaft effectively reduces engine vibration,improving ride comfort and lowering stress on the tricycle chassis and transmission.

Tricycle-optimized Construction

Features a dedicated reverse gear and reinforced mounting brackets for stable integration.High-strength gears and bearings handle heavy-duty daily use.

Fuel Economy&Low Maintenance

High-efficiency combustion minimizes fuel costs.The simplified air-cooled design reduces maintenance frequency and overall operating expenses.
