For over 25 years GHN-Racing worked extensively with SUZUKI RG500 GAMMA as both a racer and a tuner. Behind the GHN-Racing name stands Günter Nothelfer. He has actively taken part in the "500ccm German Championship" "KÖNIGSKLASSE" for 15 years. With his two personally tuned RG 500 machines, he has achieved several pedestal places as the fastest RG 500 Gamma rider. Of course, he has tuned and modified other 2-Strokes such as RGV/RS 250 as well. He can now share his wealth of experience by passing his knowledge on to interested sports motorcycle enthusiasts.

Dear 2-stroke friends,

My joy in riding 2-stroke motorcycles, especially in racing, started over 35 years ago as a hobby.
Technical changes to the machines, most of which came from painstaking adjustments over the years, have been many. Each of these changes are now used in my tuning efforts, with which the reliability and performance of the 2-stroke engine has greatly improved since I began.
In the meantime, the hobby has changed to a profession, first as a sideline, beginning in 1989.
Now, I find that the intricate work in the area of the two-strokes especially RG 500 has come full circle in the course of the time and my love of tuning has encompassed my entire life.
Without any professional advertising, but tied undeniably to sporting successes the majority of my talks with customers directly resulted in more active time at the racetrack.
With great pride, our customer list numbers nearly 800 strong, all over world.
The site's sections are divided up into easy-to-use, but descriptive pages. We hope you will find the specific information for all your sporting motorcycle needs.
Our "products A-Z", point to most products and services which we offer.
The home page covers 8 categories. The buttons for the topic change are listed respectively in the lower portion of every page.
Almost all pictures have a relatively high resolution. These sections you can store on your PC, each with a photo which opens to reveal more detailed descriptions.


Have fun "clicking" on our webside,
Best wishes for you all,
Günter Nothelfer
