The complete fork upgrade kit - your choice of springs and Race Tech Gold Valves. Also includes a set of top quality fork seals and 5W fork oil to complete the job. Everything you need to transform your mushy stock forks into suspension that really works.
You can select from various straight rate springs to customize the package to your needs.
Stock Spring Rate for XR650L: 0.44 kg/mm
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.

Repair Manuals
Based on the wildly popular Race Tech Suspension Seminars taught by Paul Thede around the world, this step-by-step guide shows riders how to make their bikes handle like the pros. Thede gives the lowdown on all types of suspension, including cartridge and non-cartridge forks as well as dual-chamber and nitrogen-charged shocks.
The three forces of suspension, testing procedures, even the black arts of chassis geometry: This explains it all. The book provides step-by-step photos of suspension disassembly and assembly as well as a detailed troubleshooting guide for dirt, street and track.
Shock
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
Because the stock shock cannot be rebuilt and offers insufficient adjustment, Race Tech developed a bolt on replacement shock to cure an under sprung and under-damped stock setup.
Race Tech's G3-S Custom Series Shocks are truly custom with spring rates and valving picked specific to each rider. Each shock is built to order featuring Gold Valves to guarantee a plush feel and great bottoming resistance while also providing more traction than any other setup on the market.
Please include your riding weight, skill level, and type of riding in the order comments.

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.
If you have '87-'07 KLR, you MUST order new mounting bolt. Not required for 2008-2018 models.
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 correct spring rate for your weight will give a smoother more controlled ride. No more bottoming and better traction and confidence off-road. Kit includes required adapter collars

- 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.
- Lighter and stiffer than stock, these high quality straight rate springs are made specifically for the DL line.
- A proper rear spring will give a smoother more controlled ride.
- Available in a multitude of spring rates, one is the perfect fit for your bike and riding style.
- Stock spring is rated at 8.2 kg/mm for the DL650, and DL1000
Adapters are required for this spring

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.
If you have '87-'07 KLR, you MUST order a new mounting bolt. Not required for 2008-2018 models.

Shock Shaft & Valving
Top suspension performance requires firm bottoming resistance with plushness at the same time. Even the best suspension tuners can only make the stock valving design work so well. The Gold Valve Shock Suspension System is a proven bolt-on shock valving system that improves control, traction, performance and bottoming resistance.
The Race Tech Gold Valve allows you to tune both compression and rebound valving for vastly improved performance.
- Bolt-on shock valving for riders serious about suspension performance
- Improves control, traction, plushness and bottoming resistance
- Improved, long-wearing, low-friction sealing design decreases fade
- Includes complete instructions
The little WRs have decent shocks but it can surely be improved with a Rear Shock Gold Valve from Race Tech. This will improve the damping in both directions and make the clickers more responsive to adjustments.
- Bolt-on shock valving for riders serious about suspension performance
- Improves control, traction, plushness and bottoming resistance

Rebound Separator Valves replace the shock shaft nut with an asymmetric valve (provides a different flow rate in each direction of travel) to increase traction and improve bottoming resistance and pitch control.
Why is this needed? On a standard shock the Low Speed Rebound Adjuster flows the same on compression and rebound. In testing, when the lowest speed rebound damping is quick enough to get good traction, the lowest speed compression damping is too mushy. This causes a vague feeling and bottoming on long duration hits like big dips or gullies in Dirt. For Pavement RSV's have the added benefit of pitch control (front to back movement during acceleration and braking). This keeps geometry more consistent.
The Valve has a partially drilled bleed hole in the center. IT MUST BE DRILLED BY THE END USER TO THE PROPER SIZE (2.8mm).
G3-LD Gold Valves provide better control for any rider by creating more shim leverage and decreasing the angular shim deflection.
