Lightweight
I
n addition to a reincarnated stylish appearance, the newly
designed and developed Suzuki DF6A and DF4A boast
the unrivaled lightweight, 24.0Kg (S-shaft models).
The lighter weight has improved portability as well as operability

Easy After-Storage Start
Because the integral overhead fuel tank and one-way valve
allow gravity fuel supply, the engine can be started without opening
the engine cover, even after longterm storage.

Highly Reliable Lubricating System
The forced lubrication system of the DF6A, DF5A and DF4A
has an additional oil passage to the upper and lower crankshaft and connecting rod big end. The addition of a first-in-itsclass** oil filter greatly increases the reliability of the lubricating system. Furthermore,
the new position of the oil window allows for visual confirmation of the actual lubricating condition.

Offset Crankshaft
Positioning the crankshaft slightly off center of the cylinder reduces
lateral pressure against the cylinder wall as the piston moves
up and down in the cylinder. The result is smoother piston movement,
which improves operating efficiency.

Quiet Operation
The low noise level is the result of a silencer, designed to optimize the
capacity and shape of the air intake. The new design of the rocker arm and
the plane bearing of the crankshaft also help reduce the noise level. We
also changed the structure of the parts related to the rocker arm and eliminated its excessive play. In addition, we changed the crankshaft bearing from a common ball type to a plane type..
