FEATURES
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).
