【Great Power】The 125cc engine has horsepower up to 7.64HP/7500±500Rpm (5.7KW/7500±500Rpm) and maximum torque up to 8.0N.m/5500±500rpm. It is a motor with great output power. Aluminum cylinder head and iron cylinder body improve the heat dissipation capability, cuts the weight and increases the torque of the engine.

【Great Durability】The 125cc 4 stroke engine motor kit is made of an aluminum cylinder head and iron cylinder block, so it has high strength and corrosion resistance. It has a longer service life compared to motors made of ordinary materials.The crankshaft connecting rod adopts large diameter bearings, which improves the reliability of the bearings. This design makes the whole machine run more smoothly.

【Good Performance】The 125cc engine's better performance leads to low noise so that you can even read a book or sleep without being disturbed. It can be used stably in various temperatures and environments, such as dusty and watery areas. The 125cc 4-stroke engine is high-pressure resistant. It is uneasy to break or damage even under high pressure.

【High Compatibility】The 125cc 4-stroke engine is compatible with many series of go karts and atv. It is highly applicable. The engine is low speed with high torque and has large diameter bearings for crankshaft connecting rod, increasing the reliability of the bearings.

【Unique Details】The engine's cylinder is covered with metal fins on the outside. When the cooling fan blows air over the fins, the heat generated by the engine is released directly into the air. You do not need to purchase an additional radiator. Lubricating oil strainer can help remove stains from lubricating oil, largely reducing the wear of friction and prolonging the engine service life.
