The Cogent Dynamics DDC valves are the most cost-effective upgrade you can make to your motorcycle’s forks. Unique and the first of its kind, a DDC kit is available to upgrade many motorcycles that are originally equipped with simple damper rod type forks as front suspension.

We do recommend stiffer than stock front springs to bring the full potential of the DDCs out. Up to about 200 pounds (rider with gear on) we recommend the .85 kg/mm springs. If you are above 200 pounds (rider with gear on) you should probably go with the 1.0 kg/mm springs.
