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.

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.

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.
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.

• Rider and Gear up to 160lb. = 0.47 springs → 24% stiffer than stock
• Rider and Gear 160-225 lb. = 0.52 springs → 39% stiffer than stock
• Rider and Gear 225-275 lb. = 0.58 springs → 56% stiffer than stock
• Rider and Gear 275-325 lb. = 0.63 springs → 66% stiffer than stock
• Rider and Gear 325 lb.-UP = 0.70 springs → 84% stiffer than stock

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 perfect option for the DIY'er.

The Cogent Dynamics Shock Shaft Assembly is ready for installation. The Cogent shock shaft also features an external rebound damping adjustment. Just what you need to have the ultimate in rear suspension control.

Does not include a spring. Compatible with both stock and aftermarket springs.

Requires 5wt shock oil

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. 
This custom Cogent valve stack makes this shock behave much like the Cogent Shock Shaft without the rebound adjustment capability.  Providing a greatly improved suspension feel over stock at an affordable price.

Spring not included, sold separate. 
Recommended spring rates:

• Rider & gear up to 150 lb = Stock 6.5 spring
• Rider & gear up to 200 lb = 7.5 spring
• Rider & gear 200-275 lb = 8.3 spring
• Rider & gear 275-350 lb = 8.6 spring
• Rider & gear 350 lb & up = 9.6 spring

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.
