Yari is the enduro option for those who ride hard on a budget.- Updated highly tunable DebonAir air spring offers a buttery smooth feel off the top and maintains a higher ride height for increased confidence in steep terrain.- New graphic package for a fresh, premium look.- Motion Control damping featuring low speed compression adjustment.- Chassis derived from Lyrik.Bottomless TokensBottomless Tokens allow you to easily custom tune your air-spring performance to best match your riding style and suspension preference. Adding the easy-to-install Bottomless Tokens changes the air-spring curve to resist bottom-out after a big hit, giving aggressive riders the power to attack the trail harder. Removing Bottomless Tokens makes the air-spring curve more linear, enhancing suspension feel for certain types of terrain or trail conditions and ensuring riders who are less front-end aggressive benefit from 100% of their fork’s travel.DebonAir Air SpringA lightweight, highly tune-able air spring designed to offer a coil-like consistent feel throughout the travel - effortlessly soaking up the smallest hits and tracking the slightest changes in the terrain.Motion ControlMotion Control damping is seamless, effective, and offers a simple low-speed compression adjustment coupled with a blow-off valve.SAG GradientsMeasurement gradients indicating the current sag and travel settings are conveniently located on the upper tubes so that you always know how much travel you are running.
