440 Series Inertia Active Shocks – The Inside Story
The 440 Series shock has been in our roster for a number of years and continues to be a top performer. Why is that? Well, street-going bikes are for the most part cursed with a limited amount of total suspension travel (generally 4” or less) and maximizing that travel is what the 440 Series shocks do best. Incorporating an I.A.S valve (Inertia Active System) that separates chassis input from road input and adjusts the damping curve on the fly, they help isolate the rider from the often harsh road below. What’s really inside these things? Take a look at this image to better understand what happens inside a shock and check out this brief video of how we make them!
