Easy to Hndle
- Lively and Powerful
The 4-cycle OHV system realizes easy starting and smoth revving
Furthermore, employment of mecanical decompression system realizes extremely llight pulling force.
- Smooth and Steady
Unique lubrication system, which separates chanber of the cylinder and crank from the oil chamber, ensures smooth, stable engine run when operatiing at a slant.
High Output
High output based on the concept of 2-cycle engine is brought into environmental friendly 4-cycle engines.
Clean and Quiet
- Clean and fuel-efficient
The clean and fuel-efficient engines comply with the EPA phase 2 and CARB tier Ⅱemission regulations in the USA which is one tenth in emission compared with a 2-cycle engine.
Also, fuel consumption is half compared with that of a 2-cycle engine.
- Quiet, low-vibration design
Extremely quiet and mild engine sound is free from working stress.
Detailed attention to the reduction of vibration creates the best in low-vibration operation.
Light and compact
The world's lightest and most compact 4-cycle engines in same displacement are brought by the unique technologies of Robin as a pioneer in compact engine design.(as of April 2002).
