HIPERMAX S Technical Feature
Dual PVS
We evolved the existing preload valve system to the dual preload valve system to suppress the
generation of unnecessary damping force during higher piston speeds.
This provides major improvement in ride comfort without influencing the driving performance.

Evolution of Bump stop rubber
A new shape of bump stop rubber reduces the body roll and achieves ride comfort at the same
time which cannot be achieved with general hydro bump stop rubber.
Wide range damping force adjustment mechanism
The improved shape of the Needle jet expand the range of damping force adjustment. This
makes us possible to handle driving on a wider range of stages.

Low friction technology
With advanced tribology technology, we have achieved even higher durability and lower friction
than conventional products. This technology contributes to improved ride quality and handling
performance.

3-year warranty
HIPERMAX S Series has a three-year warranty due to the optimization of internal parts and
quality improvement.
