We love the AirPro kits on all our bikes and we bet you will too – noticeable fork performance improvements without the hassle or $$$$$ of traditional fork upgrades.

With the added weight of a snowbike kit and aggressive riding, you’re bound to use up your travel too quickly and run into harsh bottom-out issues. The AirPro Snowbike Bottoming Kit is a quick and simple modification that allows you to add 10-15 PSI to the outer chamber of both spring and air forks, giving you an extra layer of tunability and defense against bottom-outs, or even worse, bent lower tubes.

As the fork goes through its travel, the air volume compresses and the resistance ramps up dramatically. So bottoming out is pretty much solved for like 85% of riders (the main people we still recommend a full custom fork rebuild service to are racers or folks sending 20 foot drops). The other great part about AirPro compared to a respring+revalve is that the forks remain supple off the top, maintaining small-bump sensitivity and steering feel with no harshness.

AirPro even offers a no questions asked lifetime warranty.

The kit swaps back in less than 10 minutes when the bike is ready to ride dirt trails and motocross tracks.
