Cogent Dynamics

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 Drop-in Dynamic Cartridges will vastly improve both the compression and rebound damping of your stock forks. No disassembly of your forks, no drilling of damper rods. Just change the oil to 5w and install the DDCs under the springs and hit the trails.

Stiffer fork springs are required to realize the full benefits of the DDCs. Please call if you have any further questions.

The DDCs are not recommended for use with progressive springs.

Add the DDC Install/Removal Tool which makes installation much easier.

Included in this kit are .42 kg/mm fork springs, Cogent DDC (Drop in Damper Cartridge) performance cartridges and two bottles of 5w fork oil.

These springs are custom wound specifically for the XT250. Stiffer than the stock springs, these will make your front perform significantly better. Combine them with the Cogent DDC's and you will be very happy with the results. Sold as pairs .42 kg/mm.
