Features:

Aluminum cylinder head and iron cylinder body: Improves the heat dissipation capability, cuts the weight and increases the torque of the engine.

Crank shaft: The engine is low speed with high torque and has large diameter bearings for crankshaft connecting rod, increasing the reliability of the bearings.

Air-cooled engine: There are metal fins covering the outside of the cylinders and the heat generated by the engine is released directly into the air when the cooling fan blows air over fins. It has the advantages of simple structure, light weight, wide adaptability to climate change, rapid start up and no need of radiator.

High-flow oil pump: Reduces the wear of friction pairs and prolongs the engine life.

Lubricating oil strainer: Helps removing solid contamination from lubricating oil, largely reducing the wear of friction pairs and prolonging the engine service life.

Package includes:

1x 125cc 4-stroke Engine(with accessories As the pictures)
