Who does not know about the famous DDC cartridge?
 
The Cogent Dynamics DDC valves are the most cost-effective upgrade you can make to your "dated" motorcycle's forks.
 
Unique and the first of its kind, a DDC kit is the best way to upgrade the Kawasaki KLR650, equipped initially with simple damper rod-type forks as front suspension.
 
This is a proven solution for your front suspension, which upgrades your damper-rod forks with a custom-engineered valve control system. It uses deflective shim technology to provide velocity-sensitive damping in the same way that high-end fork internals operate.
 
Each DDC is a specifically designed solution tailored to your bike's needs by changing both compression and rebound characteristics to provide significantly enhanced suspension performance.
 
The stock KLR650 suspension is known to be soft and mushy (when turning, slowing, or accelerating) but also stiff and harsh on a square-edged bump such as a pothole or rock.
This behaviour is simply due to the basic nature of the stock damper rod technology.
 
The DDC valve utilizes deflective shims and/or spring-controlled poppet valves as a type of internal pressure regulation within your forks to provide a far better level of control. You can finally have a reasonable chassis control that prevents brake-dive and wallowing along the stroke and a plush-controlled ride over rocks and washboard tracks.
 
The DDC valves have been proven in extreme environments, including around-the-world travel and motocross tracks.
 
Open your fork, replace the stock oil with a 5WT quality oil like Maxima's fork oil, and add the DDC to your fork. Unless you are a lightweight rider, you most likely need to replace your fork springs (Gen1 here and Gen 2+3 here) for a better fitting rate suited for your weight, luggage, and riding style.
