So stellst du dein Fahrwerk perfekt ein! RPG Adjustable Racing Fork 30mm Yamaha Aerox - RacingProjectGermany

Imagine your scooter gliding like it's on rails and mastering curves with playful ease. The solution to this optimal driving experience could lie in the correct setting of your racing fork. In this article we will show you step-by-step how to get the most out of this tuning part. Are you ready to take control of your driving experience?

Understand the basis

Before you start fine-tuning, it is essential to understand the basics. The correct sequence of settings and the interaction of rebound and compression are the key to an optimal setup. The spring preload determines the vehicle level and ensures the correct negative spring travel, which forms the basis for all further adjustments.

Step-by-step to the perfect setting

1. Adjust spring preload

Adjusting the spring preload is your first step into the world of fine tuning. It influences how your fork behaves under weight, adjusts the vehicle level and guarantees sufficient negative spring travel.

  • Check tools : Don't worry, you don't need a ratchet or a complicated set of tools to adjust our bars. The RPG ARF 30's included setup tool is all you need to get started.
  • Adjusting : As a rule of thumb, the fork should be compressed by about 1/3 to ensure sufficient negative travel. A zip tie around the fork can help you see how far it actually dips. If the spring preload cannot be adjusted to your satisfaction, a harder spring may need to be installed. With the RPG ARF 30 this is very easy and only takes a few minutes.

2. Adjust the pressure level (compression)

After the spring preload and vehicle level are set correctly, the next step is compression. It determines how the fork reacts to impacts.

  • Find the screw : The upper screw on the fork base, marked “C”, stands for compression. “S” and “H” show the directions for softer and harder.
  • Adjust : Start with a medium setting and then adjust to find the optimal balance between comfort and performance.

3. Adjust rebound level (rebound)

Rebound controls how quickly the fork returns after compression. The right setting ensures stability and control.

  • Locate Screw : The bottom screw, marked “R” for rebound, has “F” (Fast) and “S” (Slow) as indicators.
  • Adjust : Fine-tune to optimally adapt the fork to your driving behavior and road conditions.

Experiment and test

The key to a perfect setting is experimentation. Start with the basics and then adjust in small steps:

  • One setting at a time : Change only one parameter at a time and test extensively.
  • Test extreme values : Try setting the settings once to the minimum and once to the maximum to feel the difference in driving behavior.
  • Take notes : Record your settings so you can return to your favorite setups.

Troubleshooting & fine adjustment

Incorrect spring preload

  • Insufficient spring preload : This causes your scooter to sink deeper in curves and is less precise to steer. When braking hard, the vehicle can compress too deeply or even lock up, which is dangerous and leads to an unsafe driving experience.
  • Too much spring preload : Makes the chassis unnecessarily hard, which can lead to an uncomfortable driving experience and poorer traction as the tires do not maintain optimal contact with the road over bumps.
  • Solution : Adjust the spring preload so that the negative spring travel is optimally used without the scooter sinking too deeply. This ensures both comfort and handling. A good starting point, as already mentioned, is to adjust the fork so that it deflects 1/3 of the way when you sit on the scooter and put your feet up.

Front wheel stalls when braking

  • Cause : A pitching or pitching of the front wheel when braking hard can be caused by a compression stage that is too soft or insufficient spring preload. This causes the fork to compress too quickly and not dampen effectively enough.
  • Solution : Increase the spring preload slightly to prevent the fork from compressing too quickly. Also adjust the compression level harder to achieve less deep compression and thus more stable braking behavior. It is important to find a balance so that the scooter remains stable without significantly compromising ride comfort.

Incorrectly adjusted rebound

  • Uneven ride : If the scooter starts bouncing on uneven roads or feels unsteady, this may be a sign that the rebound setting is too hard. Returning the fork to the starting position too quickly can result in loss of traction.
  • Solution : Soften the rebound to allow for a smoother and more controlled return of the fork. This improves traction and overall handling on uneven surfaces.


You are now well equipped to adjust your racing fork perfectly to your needs and the track characteristics. With patience and precision, you will find the perfect setup that meets your riding style and needs. The journey there is an adventure – enjoy every curve!
