HIGH OUTPUT, TORQUE AND DURABILITY
404cc displacement which is the largest among 13 horsepower classed engines, produces high torque from the low speed range. High durability with less than 1% horsepower drop after 300 hours of full-throttle operation.

CAMSHAFT DRIVE 2 TO 1 REDUCTION
Like other Robin Engine models, camshaft drive 2 to 1 reduction is available. (B type) This structure is superior to an external reduction gear box, providing lighter weight, compactness, higher efficiency and lower noise.

HEAVY DUTY CONSTRUCTION
Reliable structure with cast iron cylinder sleeve and dual air clean er element. Also, heavy duty ball bearings installed on both sides of crank shaft.

SUPERIOR OIL CONTROL
In addition to the excellent oil control by 3 pieces oil rings, improved breather system, adoption of valve stem seal and high cooling capability reduce oil consumption. This enables longer oil maintenance interval.

EASY TO START
Combination of new electronic ignition and mechanical decompression system reduces pulling force of recoil starter and provides reliable startability with the first pull.
