Suspension

Use this installation tool from Cogent to be sure that your Cogent Drop-in Dynamic Cartridges are installed correctly. A strong magnet in the end holds the cartridge firmly while you lower it into your fork leg. Then slide the spring over the tool until it holds the DDC down, then gently remove the tool. That simple. Never again question if it is properly seated on the damper rod.

Works equally well for removal when you need to change your fork oil. Also works great with Race Tech Emulators.

These Cogent Dynamic Drop-in Cartridges will vastly improve both the compression and rebound damping of your stock forks. These units have been given the seal of approval by the ProCycle staff for both performance and ease of installation. No disassembly of your forks, no drilling of damper rods. Just change the oil over to 5w and install the DDCs under the springs and hit the trails.

Stiffer fork springs are recommended to get the full potential of the DDCs.

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.

You can adjust the preload on your rear shock quite easily, why not on the forks as well? These caps give you the ability to adjust the spring preload in your forks to match your load.

Caps are CNC machined beauties with a center blue anodized core.

Cogent Dynamics fork caps not only look fantastic they also add the ability to precisely adjust the preload of your fork springs to best match your needs and compensate for different loads and conditions.

Spacer will need to be custom depending on specific application, rate and length. Generally speaking, start with more preload if progressive, less preload if straight rate.

The Cogent Dynamics kit is a simple and effective way to improve the damping for your Africa Twin forks. The AT-1 kit includes two new replacement fork base valves to completely revalve your forks in a straightforward pre-assembled kit. This kit is the adventure proven and suspension dynamometer tested kit for your CRF1000L front suspension. It uses new CNC aluminum damping pistons, valve stacks and check systems which come to you pre-assembled onto a base valve adjuster housing. This means you won't need a micrometer and valve shim experience to achieve the results you need. The Africa Twin 45mm upside-down fork uses sealed top cartridges.

This unique arrangement allows Africa Twin owners to do a simple disassembly of the fork, removing the cartridge and replacing the stock base valve assembly. Your stock valving assembly can be retained while the new AT-1 kit improves your suspension performance.

We suggest installation of stiffer fork springs along with the Revalve Kit.

Included in this kit are fork springs, Cogent DDC (Drop in Damper Cartridge) performance cartridges and three bottles of 5w fork oil. Refresh those tired old forks and make them better than new. These DDCs from Cogent are easy to install. No taking the forks apart, no drilling of the damping rods, nothing. Just take them off, flip them over to drain the oil, add new 5w oil, drop in the DDCs and then add the springs and spacers and then install the caps. Preload spacer material is included with the .47 and .70 springs, additional spacers are not needed with the other kits.

Stock Spring Rate for XR650L: 0.44 kg/mm

In stock form, the forks, featuring a single spring design are under sprung for any rider over 100 pounds. With limited travel, adding a stiffer spring in the right leg only per the stock design was not a viable option.

Race Tech instead offers a Hi-Performance Spring Kit that adds a stiffer spring to the other fork. (The overall spring rate in the forks is the average spring rate between both legs.) This upgrade will make a drastic improvement in handling for most riders.

0.50KG/MM KIT
