HIPERMAX S Technical Features 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. 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. 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. 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.
