Supermoto is a very specialized setup and Race Tech knows Supermoto! We have been providing setups since the beginning of this exciting class and we continue to fine tune and update settings to offer the Supermoto Racer the best there is!

SuperMoto suspension has 
3 specific considerations:

  1. Maximum traction.
  2. Pitch control – this means controlling excessive front to back movement (which really is a geometry consideration).
  3. Bottoming control.


Up front this means G2-R Gold Valves, Rebound Gold Valves and proper Springs.  At the rear, Gold Valves and Springs.

 Chassis Geometry is a major concern. With the use of ►Scheibner Mega-M.A.X. we have identified major problems with the standard Supermoto setup.  To cure these problems we recommend individual measurement on the Scheibner Mega-M.A.X.chassis measurement tool.  The proper setup requires new Fork Bottoms and/or Triple Clamps.

The first step to great handling is selecting proper spring rates front and rear. With over 500 Hi-Performance Springs to choose from, Race Tech is almost guaranteed to have the spring you need.

Through years of testing and manufacturing experience, Race Tech has developed a full line of Hi-Performance Springs using the finest materials and processes. RT Springs have the highest stiffness-to-mass ratio in the industry; making them extremely light weight for their particular rate.


RT Hi-Performance Spring Features:

-Extremely accurate rates

-The tightest tolerances in the industry

-Heat-treated and Shot-peened

-Preset to eliminate sacking-out

-Extremely lightweight

-Made in the USA

Race Tech's award winning Gold Valve Kits for Forks and Shocks provide a personalized setup. Gold Valves have an improved flow design that dramatically reduces harshness while actually increasing bottoming resistance (as shown with data acquisition). These Kits can be installed by individuals interested in understanding and tuning their own suspension or they can be installed by a Race Tech Center or Race Tech's Service Department. The Kits include Valving Charts and Valving Shims to allow a custom setup for a specific rider and conditions.

Fork Rebound Gold Valve Kit: Many stock rebound valving systems are grossly inadequate. No matter what modifications are attempted, the stock valves will never perform with precision or control. If you race or simply want the best, Race Tech's Rebound Gold Valves are the solution to improved traction. Used by major factory teams, these valves increase flow area, putting valving control on the shim stack instead of the piston. This results in outstanding tuneability, improved control and traction.

G3-LD Shock Gold Valve Kit: Guaranteed to provide better handling and each kit includes a Gold Valve and a personalized valving setup. You may install the kit yourself, send it to Race Tech, or send to your local Race Tech Center for installation. The G3-LD Gold Valve design creates better flow allowing improved bottoming resistance, plushness, control and traction as well as increased tuneability.

Benefits of Gold Valves:

    -Increased tuneability

    -Personalized setup

    -Reduced harshness

    -Increased bottoming resistance

    -Improved traction

    -Consistent feel

    -Technical support

    -100% Guaranteed

    -Made in the USA





Rebound Separator Valves replace the Shock Shaft Nut and with an asymmetric valve that flows through the Low-Speed Rebound Adjuster. This means Low-Speed Rebound Damping can be set for excellent traction while keeping the Compression nice and firm. This dramatically increases traction while giving better bottoming resistance.





Get the jump on your competition straight out of the gate with a double-button Race Tech Holeshot Device. The double button design provides an optimal setting for varying soil conditions without the hassle of changing fork guards or re-mounting your starting device. The large latching area makes for easy setting while a machined lip and extra large stainless screws keep the device securely in place.

- Available for most minibikes and big bikes

- CNC machined from aircraft grade aluminum

- Easy install template tool included

- Made in the USA





Stock Honda steering dampers come with an under-damped feel with a small amount of adjustability. To help the steering damper become more effective and predictable, Race Tech has developed a Steering Damper Gold Valve Kit to increase damper performance and adjustability. The kit comes with instructions for 3 settings: soft, standard and hard.



Race Tech has developed a 19mm Shock Shaft Kit to greatly improve the performance of your stock shock. The benefits of a larger shaft include more flow for increased adjustment, and also provides improved strength. Available for Japanese motocross bikes with 16mm stock shock shafts.

The 19mm Shaft Kit features an 8 clicks per revolution rebound adjuster for improved fine tuning. Dyno testing verifies compression adjustment range is increased by nearly 4 times, and rebound adjustment range offers nearly a 50% increase. Flat Track requires more suspension tuning track-to-track than any other genre of motorcycles due to a wide variety of soil conditions and banking. This makes the 19mm Shock Shaft Kit particularly important. The 19mm Kit provides a significant increase in overall range while the additional clicks create more precise adjustments.




Look no further for the ultimate suspension solution for the rear of your Custom Frame or Vintage dirt tracker.  Race Tech's G3-S Custom Series Shocks are personalized, built-to-order in the USA specifically for your setup, size, skill level, and application.  Available in (nearly) any length and 100% GUARANTEED to exceed even your highest expectations.

IFP, Remote Reservoir, and Piggyback shock options are available


Coatings drastically reduce friction to provide a smooth and consistent feel, as well as provide an excellent resistance to wear.

Diamond Like Coating (DLC2):

DLC2 is the best of the best when it comes to coatings. Applied to the exterior of the chrome tubes, it is extremely hard and slippery.

DLC2 Coating Benefits:

- Excellent resistance to wear

- Creates extremely hard and slippery surface

- Creates "factory" look

More info about DLC2 Coating

Fork Tube & Shock Body Hard Anodizing:

Hard anodizing is a treatment for aluminum surfaces only. Many of today's stock forks come with the aluminum outer tubes hard anodized from the factory; however, the coating is many times very thin - wearing through in less than 10 hours of riding. Once worn, bushings ride on soft aluminum creating friction and an inconsistent feel.

Hard Anodizing Benefits:

- Excellent resistance to wear

- Hardness provides reduced friction

- Allows exterior surface color option
