Race Tech offers multiple suspension upgrade options to take your Race Bike to the next level. Production sportbikes suspension settings are generic, as a Racer you need a setup tuned to your specific needs and riding style. With varying rider weight, ability and track conditions, the "average rider" production suspension settings  won't be up to a Racer's requirements and won't provide the traction and confidence Racers require. We offer custom suspension setup for your needs  with a variety of options to choose from

Tire wear can make or break your race results. Proper Suspension Setup is essential to consistent tire performance lap after lap.

Chassis Dynamics are also critical, Race Tech can analyze and optimize your chassis geometry. 

If you ride your bike on both track and on the street we have suspension solutions for that option as well

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
