The Micro line of Robin Subaru engines are known for their eco-friendly, 4-cycle OHV design that cuts emission rates to 1/10 of that of a two-cycle engine and uses half the amount of fuel. They start after just one pull thanks to an automatic decompression system, and have a connecting rod and needle bearing inserts that ensure bearing support and reliable performance.

While Robin Subaru engines are compact, they are fitted with a carbon steel crankshaft allowing them to perform heavy load applications. Despite the load, they remain maneuverable, quiet and reduce the user's fatigue. They also have a unique lubrication system that separates the oil chamber from the rest of the engine so it runs smoothly, no matter the operating position. The oil chamber fits oils SAE 10W-30 SF or higher and can hold 2.7 liters.
