About this item

  • This motor is made of aluminum cylinder head and iron cylinder block. The aluminum cylinder head and iron cylinder block improve heat dissipation, reduce weight, and have high strength and corrosion resistance. The high flow oil pump reduces the wear of frictional subsets and prolongs the life of the engine.
  • The engine has high torque at low speed, and the crankshaft connecting rod adopts large diameter bearings to increase the reliability of the bearings. This design makes the whole machine run more smoothly.
  • The 125cc four-stroke engine cylinders are covered with metal fins on the outside. When the cooling fan blows air through the fins, the heat generated by the engine is released directly into the air, and you don't need to buy an additional radiator.
  • This engine has a lube oil filter, which helps remove solid contaminants from the lubricating oil, largely reducing frictional wear and extending the life of the engine.
  • It has simple structure, light weight, wide adaptability to climate change, and can be used stably in various temperatures and environments, such as dusty and watery places, and starts quickly.

Installed and put new honda oil in it. My 5 year old drove it around for a week and a half now won’t run. Disappointed, should have bought a nicer option

Of these engines over the years. We have a couple kids chinese 4 wheelers and dirt bikes. This particular engine is suitable for the 4 wheelers and they run fantastic with proper adjusted carbs. They break in easy, I always run Motul full synthetic oils after the initial couple hours of break in and no issue.
