Stock Spring Rate for XR650L: 0.44 kg/mm

In stock form, the forks, featuring a single spring design are under sprung for any rider over 100 pounds. With limited travel, adding a stiffer spring in the right leg only per the stock design was not a viable option.

Race Tech instead offers a High Performance Spring Kit that adds a stiffer spring to the other fork. (The overall spring rate in the forks is the average spring rate between both legs.) This upgrade will make a drastic improvement in handling for most riders.

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.

RT Ultra Slick Grease provides maximum lubrication and minimum friction for seals and bushings. Great for engine seals too.

• Special compound for minimum friction and maximum lubrication
• Perfect for fork seals, bushings and O-rings
• Available in 1-fluid ounce jar

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.

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).

Quality replacement parts for servicing your shock.

• Shock seal head and bushing
• Oil and dust seal
• Shock bumper

Damping Rod style forks are notorious for being too harsh, too mushy and too easy to bottom. Gold Valve Cartridge Emulators remedy this problem by controlling the compression damping with a tuneable valve. The Emulator sits on top of the damping rod and is held in place by the main spring.

Simply put; Emulators make damping rod forks perform like well-tuned cartridge forks. Installation and tuning for any condition or rider preference is very straight-forward. 

Simple to install and completely tunable for all conditions and rider preferences.

Combo Kits include both Compression as well as Rebound/Mid-Valve Kits with a significant cost savings over purchasing these kits separately. In the "good 'ole days" we got away with just Compression Valving improvements. However, Rebound/Mid-Valves are critical for any modern hi-performance valving setup.

Type 3 Gold Valves are the latest version of our bolt-on fork valving system for cartridge forks. Gold Valves significantly improve the flow over stock pistons, putting valving control on the shim stack instead of the piston. This results in outstanding tuneability, improved control, traction, plushness and bottoming resistance.

Includes detailed online instructions, Gold Valve Pistons, Valving Shims, and access to the Digital Valving Search (DVS) which provides specific valving stacks for your exact weight, skill and riding conditions.

G3-LD Gold Valves provide better control for any rider by creating more shim leverage and decreasing the angular shim deflection.

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.
