The 412 Series shocks are simply the best value shock on the market today. The 412s simple, durable design means they will be an improvement to your motorcycle's suspension performance for as long as you are riding it. The doublewall steel body construction with nitrogen charged, multi-staged velocity sensitive valving gives you smooth, consistent damping. A five-position cam style preload adjuster lets you dial in your ride whether you're a light rider or heavy hitter.

Target Ride Length (in) : 12.25 
Target Ride Length is the length of the selected shocks, installed, and as measured between the upper and lower shock mounts, when the full weight of the rider(s) & gear are on the bike and ready to ride. This is a fast and easy way to set your rear suspension at optimum Ride Sag (1/3 of total suspension travel)

With the shocks selected above installed and the full weight of the rider(s) & gear on the bike as it will be ridden, measure the distance between the upper and lower shock mounts (center to center). If your measurement is less than the indicated Target Ride Length, increase the spring pre-load** to raise the bike until you achieve the Target Ride Length. If your measurement is more than the indicated Target Ride Length, reduce the spring pre-load** to lower the bike until you achieve the Target Ride Length. Achieving the Target Ride Length in this manner sets the rear suspension ride sag for optimum performance and comfort.
