Custom-made to Baron’s specifications by Eibach Springs, these units improve damping control while eliminating bounce. The 930-lb. spring rate (Road Star/Warrior) and 800-lb. spring rate (V-Star 1100) was calculated, tested and determined to be the best possible for riders with lowered motorcycles and/or those carrying passengers. See our Spring Compression Tool (BA-8525-00) for easy do-it-yourself installation. Note: Changes to suspension that lower motorcycles, change spring rates or affect damping can change the way your bike handles, including angles of contact when cornering. Use caution after installing these products.
