Standard snowbike setups weigh 65 to 85 pounds more than a stock dirt bike (BEFORE you add racks, packed snow, spare gas, etc), which can lead to violent bottoming and bent lower fork tubes. The AirPro allows riders to add 8-15 PSI to a spring fork, significantly increasing bottoming resistance and ride height. This accessory provides a low cost option for riders to achieve great results while using independently, or in conjunction with a front fork revalve/respring (depending on rider skill level).
