The V-Strom suffers from poor compression damping and limp rebound damping. 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

Designed and built for Dual-Sport and Adventure bikes, the Nitron Adventure Series R1, R2 and R3 shocks offer exceptional road and trail performance. Using billet aluminum components, a large heavy-duty 16mm piston rod and a high-flow capacity 46mm piston, this shock flows much more oil for a more consistent, fade-free performance than most other shocks.

Nitron shocks are custom built for your specific weight, if you have a passenger or luggage add that weight as well. Lastly your riding conditions; do you ride mainly paved roads, dirt roads, trails? Please provide a percentage of each you ride. This information is essential to the building of the shock. Enter this in the comments section of the shopping cart when you check out, or feel free to call and place your order over the phone.

• Includes the lower shock bearing and all other parts necessary to rebuild the suspension linkage
• 52100 bearing steel and hard-plated spacers resist wear and rust
• Each kit includes the lower shock bearing, all the shafts, seals and spacers in the link, link arm and lower shock mount

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 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.

Heavy duty shock bumper. The stock bumper is prone to disintegrating with age. If you are re-valving your shock it's a good idea to be sure the bumper is in good shape.

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.

Sized perfectly for adult back-yard racing or fast/aggressive mini riders. This is the most important upgrade you can make for an adult sized rider. The stock suspension is too soft for most adults and aggressive kids. Fits stock 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

Don't want to buy a new shock? This rebuild makes the stock shock about 10 times better. We send shocks to Cogent Dynamics. They clean them up, hard anodize the bodies for better wear, and install new Shock Shaft Assemblies with rebound damping adjustment.

Any aftermarket spring for your stock shock will fit on this shock. If you are 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.

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 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.)

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).

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

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.
