* This table is a general guide for setting proper sag of 30-35% or 2.7"-3" of sag. Keep in mind your upgrades on your bike to select the proper spring size. For example if you have an aftermarket battery it could have added 30lbs to your bike. Some riders might also prefer softer or stiffer springs.
