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 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.

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.

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.

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.

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

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.

NOT recommended for the Adventure Sport ES

Included in this kit are fork springs, Cogent DDC (Drop in Damper Cartridge) performance cartridges and one bottle 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.
This upgrade offers better control off-road as well as on. Less brake dive keeps the fork up in the middle of the stroke on-road and better control off-road whether it be rolling water bars or bouncing off the rocks.

Stock Spring Rate is .50 kg/mm. The .60 kg/mm springs are 20% stiffer than stock while the .70 kg/mm is 40% stiffer than stock.

Developed by the KLR suspenison experts at Cogent, this set of springs will stiffen up that wimpy KLR front end. Choose between .64 kg/mm springs (60% stiffer than stock) or .70 kg/mm units (75% stiffer than stock).

A dual-rate fork spring for the early KLR650. These springs start with a .40 kg/mm winding and after approximately 20% of the stroke, stiffen up to .60 kg/mm for the remainder of the travel. A very nice improvement over the stock springs which are .40 kg/mm for the entire travel.

The progressive factory springs are well known to be way to soft for most riders. Cogent Dynamics straight rate springs will give better control in the rough stuff and when loaded up.

Sold in pairs.

The .72 springs are 28% stiffer than stock and will be a great choice for most riders

The Moab shock from Cogent Dynamics will change how you feel about your KLR. You may like it now, maybe even like it a lot, but you will absolutely fall in love with it once you mount up a Moab shock.

Spring duties are handled by a custom spring available in either Standard or Heavy-Duty weights. The Standard spring will be fine if you are under 250 pounds and don't ride with luggage or passengers often. Ride heavily loaded or with a passenger regularly and you will probably want the Heavy-Duty spring.

For a true comfort and performance package, we highly recommend upgrading your front suspension at the same time.

The Moab shock from Cogent Dynamics will change how you feel about your GEN 3 KLR650. You may like it now, maybe even like it a lot, but you will absolutely fall in love with it once you mount up a Moab shock.

Spring duties are handled by a custom spring available in either Standard or Heavy-Duty weights. The Standard spring will be fine if you are under 250 pounds and don't ride with luggage or passengers often. Ride heavily loaded or with a passenger regularly and you will probably want the Heavy-Duty spring.

There is very limited manual preload adjustment access on the Gen 3 KLR650 without removing the shock. Therefore, the addition of the Remote Preload adjuster gives you the convenience of optimizing your rear suspension spring preload for quick leveling (load compensation) of your bike to accommodate a passenger, luggage or just to change ride characteristics based on your preferences.  The adjustment which would normally require reaching the shock in your bike to turn a threaded collar using a tool can be easily adjusted by twisting a remote knob which uses the convenience of hydraulics to change the spring preload up to 100% (9 mm total range of preload change).

There is a mounting conflict for the Remote Preload adjuster with the Happy Trails and T-REX crash bars.

The Moab Pro-Series shock from Cogent Dynamics is the standard by which all other shocks are judged in the KLR world. With its superior performance and exceptional reliability, Moab Pro-Series shocks have literally conquered the world many times over. The staff at Cogent is as passionate about motorcycles as you are.

Spring duties are handled by a custom spring available in either Standard or Heavy-Duty weights. The Standard spring will be fine if you are under 250 pounds and don't ride with luggage or passengers often. If you regularly carry luggage boxes and/or a passenger and weigh over 250 pounds, you will probably prefer the Heavy-Duty spring. Call if you have any questions.

Because of the limited space with the reservoir, adjusting your preload is just about impossible and for that reason we only sell these units with the Cogent Hydraulic Preload Adjuster already installed!

For a true comfort and performance package, we highly recommend upgrading your front suspension at the same time.

The Modoc is an excellent replacement for the stock shock. With adjustable rebound damping and preload, you can tailor the performance to match your riding style.

Select the spring you want installed based on the load you plan to carry. For most riders, the 7.1 kg/mm spring will suit you perfectly. Weigh more than 250 lbs, or are loaded to the max, think about the 8.1 kg/mm spring. Please call with any questions.

Cogent Dynamics Mojave product is a drop-in replacement for the DR650 stock shock, no modifications necessary. Mojave is not simply an improved Suzuki shock, it is a brand new replacement shock that is a totally engineered suspension solution to suit your needs.

Each shock is assembled and tested on the Cogent Dynamics suspension dyno before being packed up and shipped. Like its bigger brother the Mojave Pro Series, this will make an incredible difference in the handling of your DR.

Mojave Improvements over stock
Mojave upper mount: uses a precision spherical bearing with dust seals, which accurately transfers damping forces to the motorcycle frame.

Internal improvements: Cogent designed shaft, seal head, damper piston, adjuster and clevis.
Mono tube construction: precision honed, super-stiff steel body with an upper body cap machined from billet aluminum.
Built-in billet aluminum separator piston provides an in-line gas pressure reservoir which eliminates the Suzuki rubber bladder.

This shock package includes the CNC machined Bling Ring Preload Adjuster Collar and Preload Bearing that will make preload adjustments easy.

Select the spring you want installed based on the load you plan to carry. For riders (and gear) less than 250 pounds we recommend the 7.6 kg/mm spring. If you regularly have more than 250 pounds the bike, you might want to use the 8.15 kg/mm spring. If you have any questions at all about this, please call.

You may choose to add the Hydraulic Preload Adjuster to make it the easiest of all. All you do is twist the knob. Includes mounting bracket for knob unit. (Some CA carb compliant models may need slight modification for mounting the preload adjuster.)

Low shock also available. This option will lower your seat height 1" without the need for lowering links. All other features of this shock are the same as the stock height.

The Pro-Series is the suspension performance pinnacle. Cogent takes Mojave’s best-in-class performance and adds an external reservoir.

The Pro-Series’ sophisticated reservoir with interchangeable valves and shims, provides more tune-ability at all speeds. It also improves internal pressure balance and temperature dissipation, giving long lasting performance regardless of the punishment you put it through.

Comes standard with the CNC machined Bling Ring Preload Adjuster Collar and a thrust bearing between the adjuster ring and the spring making preload adjustments easy.

The optional Hydraulic Preload Adjuster makes it even easier to adjust the preload. Just twist the knob. Includes mounting bracket for knob unit. (See last image)  (Some CA carb compliant models may need slight modification for mounting the preload adjuster.)

Select the spring you want installed based on the load you plan to carry. *Spring color may vary due to specification requirement and availability.

For riders (and gear) less than 250 pounds we recommend the 7.6 kg/mm spring.

If you regularly have more than 250 pounds on the bike, you might want to use the 8.15 kg/mm spring.

Low shock also available. This option will lower your seat height 1" without the need for lowering links. All other features of this shock are the same as the stock height.

The Pro-Series is an excellent replacement for the stock shock. With both compression and rebound adjustable as well as preload adjustable, you can tailor the performance to match your riding style. Compact and rigid design with piggyback type reservoir specifically engineered for your WR250R. Fully serviceable shock is designed for the long haul.

Select the spring you want installed based on the load you plan to carry. Choose the 'standard' 8.15kg/mm spring for rider/ luggage up to 220lbs. Weigh more than 220 lbs, or are loaded to the max, think about the 10.19kg/mm 'heavy' spring.

Cogent Dynamics has created another winner - the 'World's Edge' shock for the 650 V-Strom the rear end you have wanted for all these years. This unit gives the DL650 excellent control with a firm but comfortable ride, both solo and two-up. This shock is equipped with adjustable damping control so you can customize the action to your preference. Please call for lowering options also if you need them.

The Bling Ring preload adjuster and thrust bearing on the spring make preload changes easy when you fill the bags and add a copilot. Keeping the ride height up can make the difference between a good handling motorcycle and a peg scraping pig. Want to make it easier yet? Add a Hydraulic Preload Adjuster like the stock shock has.

Includes mounting bracket.

  Bikes with ABS require the hydraulic preload adjuster

The Öhlins Africa Twin shock has knob adjustable rebound and compression damping on a 46mm machined aluminum body combined with a hydraulic remote preload adjuster with a hose mounted actuator and mounting bracket. The gas reservoir uses a much higher quality compression adjuster/head valve along with a solid separator piston to prevent gas bleed-over. The improved adjuster circuits provide a wider range of adjustability.

Solo riders with light loads should select the 9.7 spring. 2-up riders or heavier loads select the 10.7 spring.

Features and benefits of this Öhlins shock:

• Damping rates optimized for your bike
• 46mm damper piston with high quality wear-band
• Low internal friction
• Piggyback type remote reservoir with separator piston
• Fully serviceable with famous Öhlins Quality is designed for the long haul

Cogent Dynamics 10.27 kg/mm shock spring for the big Honda. This will help you get through the whoops or just help handle that extra baggage on the rear. This is 15% stiffer than the stock spring. Designed to be the correct fit for the Honda OEM rear shock on your Africa Twin so that it fits your shock without modification.

*Spring color may vary due to specification requirement and availability.

The KLX 250s comes softly sprung which can be great for lighter riders who are not using the bike for hard off-road riding. This Cogent Dynamics, custom engineered spring fits your shock like the OEM spring (without spacers or adapters) and firms up the rear suspension.

• 2006-current KLX 250s 6.2 Kg/mm for most riders 150 to 200 lbs
• 2006-current KLX 250s 7.0 Kg/mm for most riders over 200 lbs + or for more aggressive riding conditions.

*Spring color may vary due to specification requirement and availability. 

This 'Bling Ring' replaces the two stock preload/lock rings. The ring is CNC machined aluminum with the additional thickness to provide superior support on the shock body.

The added needle bearing thrust washer will make preload adjustments much easier. The ring then spins much easier against the spring making adjustments quite a bit easier.

This part can easily be added to the Cogent or Race Tech Shock Shaft Assemblies, even after they are built.

To install the Bling Ring on a shock with a stock shaft it must either be disassembled or have the lower clevis removed.

Don't want to buy a new shock? This rebuild makes the stock shock about 10 times better. Cogent Dynamics takes a stock DR650 shock, tears it down, cleans it up, adds a hard ceramic coating, then rebuilds it with a completely new Shock Shaft Assembly with rebound damping adjustment.

Any aftermarket spring for your stock shock will fit on this shock. If you are currently using the original spring, you will want to order a stiffer spring to go with your new shock. 

Our 7.5 kg/mm rear spring is 16% stiffer than the stock one and is perfect for the majority of riders. If you are a larger rider, or carry a lot of gear or a passenger (total weight exceeding 250 pounds) you will probably want the 8.3 kg/mm rear spring which is 28% stiffer than stock.

This shock includes the Bling Ring preload adjusting ring AND the Thrust Bearing! This replaces the two stock preload/lock rings. This ring is CNC machined aluminum with the additional thickness to provide superior support on the shock body.

Low shock also available. This option will lower your seat height 1" without the need for lowering links. All other features of this shock are the same as the stock height.

Cogent Dynamics takes a stock DR650 shock, tears it down, cleans it up, adds a hard ceramic coating, then rebuilds it with a completely new custom shim stack that gives you excellent rear wheel control.
