One common problem is the inability of the shock to transfer fluid from the shock body to the reservoir fast enough to absorb high-speed hits. With larger diameter shafts, this is even more important. The answer is the special hose from MOTOWOZ. This allows fluid to pass quickly to the reservoir, which helps to eliminate that high-speed harshness that so many ATV racers have come to accept as “unavoidable". Allowing this fluid to pass more freely through the hose puts more control back into the valves where it should be.
