Overall driving performance on a wide range of surfaces is fundamentally influenced by the suspension. Because of this, suspension oil needs to be incredibly effective. The extremely large jumps made by dirt bikes are just as much a source of intense stress as the unbelievably fast small movements made by a racing motorbike. And in between the two, there is a whole host of motorbikes with a wide range of applications. The suspension continuously compensates for everything between the motorbike and surface. The fact that it needs a specially developed suspension oil to do this goes without saying.
