DR650: Suspension

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.

Race Tech Hi-Performance Fork Spring have the highest stiffness-to-mass ratio in the industry. This means they are lightweight for their particular rate. These spring designs have taken years of manufacturing experience. They require the finest materials and processes.

Race Tech Hi-Performance Springs have extremely accurate rates. They are heat-treated, shot-peened and preset so they cannot sack out.

OEM spring rate is 0.42kg/mm. 

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.

Race Tech Cartridge Emulators make damper rod forks perform like well-tuned cartridge forks. Emulators are tunable valves that sit inside your forks on top of the damper rods and are held in place by the fork springs. Simple to install and completely tunable for all conditions and rider preferences.

Kit includes all the fork bushings, o-rings, snap rings and washers this kit comes with what it needs to completely rebuild your front fork bushings

Patented fork seal features a balanced 3 lip design that evenly distributes the pressure reducing operating temperature, wear and friction

Custom Elastomer Fork Seals have been tested to outlast OEM fork seals. Extends typical seal life by 3 to 5 times over OEM seals

Stiction (friction) measures from 1/3 to 1/2 less than OEM seals for smoother fork action

Lower Stiction, Longer Life! It doesn’t get any better than this!

Plus, the only complete line of dust wipers! Wipers should be replaced with the fork seals to assure peak performance. 

Kit includes Fork Seals and dust wipers.

 

An excellent replacement for the stock fork boots. These are great for protection from dirt, rocks and other contaminants. These boots utilize the latest advances in material technology to adapt to fork and styling demands. These high quality fork boots are 1/4 the price of the OEM factory replacements.

Split design means that installation takes minutes without having to remove the forks. Available in a black anodized finish.

Helps protect vulnerable fork tube and seal from dust, dirt, and corrosive elements. Hook & loop (Velcro) fastening on back side makes installation or removal for cleaning a breeze.

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.

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 that 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.

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 its Shock Shaft brother below without the rebound adjustment.

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.

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.

 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

Replace the internal components in your shock with a completely updated design with adjustments for both compression and rebound damping.

The new shaft assembly has improved valving for both compression and rebound, a thicker, stronger shaft, new seal head and bottoming bumper. Comes as a complete assembly ready to go into your shock body. You can add choice of rear spring (required).

Add a bottle of 3w Shock Oil to your order so you can start your project right away.

The complete shock upgrade kit - a shock spring of your choice, Race Tech Gold Valve kit, detailed instructions and a bottle of quality shock oil to complete the job. Everything you need to transform your mushy stock shock into suspension that really works.

Recommended 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

The correct spring rate for your weight will give a smoother more controlled ride. No more bottoming out, and improved traction and confidence off-road.
8.6 & 9.6 springs require an adapter which is included.

Recommended 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

For a top notch rebuild or re-valve of your rear shock use this high quality replacement seal head.

• Complete assembly, ready to install into the shock body
• Has air bleed holes to help remove air from the oil reservoir during installation
• Double-lip oil seal design keeps out dirt and keeps friction low
• Kits include aluminum body, dust seal, bushing, oil seal, O-ring, internal guide bushing/washer, snap ring, and top-out bumper

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.

This thrust bearing is designed to sit between the shock spring and the preload adjusting nut on the shock. This bearing will eliminate spring binding during shock action and will make turning the preload collars much easier. The bearing kit includes two cupped washers, one thrust bearing and inner & outer o-rings to keep out water and dirt.

Stock suspension 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 serious suspension performance
• Improves control, traction, plushness and bottoming resistance
• Improved, long-wearing, low-friction sealing design decreases fade
• Includes complete instructions

Complete kit to replace the bearings and seals in the DR650 shock linkage. Includes the lower shock bearing.

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.

Complete kit of OEM quality parts to replace the bearings and seals in the swingarm pivot.

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.

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.

• Extracts dirt and debris trapped between fork seal and tube
• Easy way to keep fork seals clean and debris free
• Works on conventional and upside-down forks

Innovative design makes tool easier and more secure to use than old fashioned pin-aligned drivers

• Knurled anodized aluminum locking ring
• Perfectly weighted to drive seals
• Carbon steel body halves

Keeps the damper rod from turning so you can remove the bottom fork bolt. Perfect when replacing fork seals or installing cartridge emulators. It's a good addition to any tool box as it will fit many other bikes.

Showa removed the schrader valve on many newer rear shocks. Now you need a needle to recharge your shock with nitrogen after a rebuild. Race Tech built this unit just for that job.

The features of this tool include 300 psi capacity, bleeder valve and T-handle plunger pin chuck. Swivel chuck has a 12" flexible hose. Comes complete with instructions, carrying box and Schrader valve extension (required on some Showa shocks). Nitrogen bottles available at any welding supply house.
