Advanced Setup

Determining the firmness or aggressiveness of the high-speed and low-speed adjustment settings for the Prime Series Emulators would depend on your personal preferences and riding style. Here are some general guidelines to help you assess the settings:

High Speed Screw

High-Speed Adjustment: The high-speed adjustment controls the compression damping during fast, sudden impacts such as hitting a large bump or landing from a jump or wheelie. If the setting is on the firm side, the forks will resist compressing quickly, providing a more controlled and stable feel. On the other hand, a weaker setting will allow the forks to compress more easily, resulting in a softer and more compliant suspension.

Low Speed Screw

Low-Speed Adjustment: The low-speed adjustment affects the compression damping during slower movements, like braking or cornering. A firm setting here will provide more stability during these actions, reducing front-end dive under braking or excessive movement during cornering. Conversely, an weaker setting will allow more movement and compliance in these situations.

Adjusting Balance between high speed and low speed dampening

The effects of the high speed dampening can be delayed to balance out the transition from low speed damping to the more aggressive high speed damping. This has the effect of utilizing the more aggressive damping only when hitting larger potholes or bumps. To change how strong the more aggressive dampening mode will be when active, change the high speed setting.

Rebound Control

The adjustment of fork rebound plays a crucial role in fine-tuning the handling characteristics of your motorcycle. It controls how quickly the fork extends after compression, affecting the rate at which the front suspension returns to its original position.

Slowing down the rebound speed can increase control by preventing the front forks from extending too rapidly. It helps to manage weight transfer during braking, keeping the front end from bouncing excessively, thereby maintaining better traction and control. Dampening the rebound motion of the fork can also reduce the amount of recoil felt by the rider through the handlebars.

The rebound motion of the fork can be adjusted by twisting the collar located between the two black O-rings. The hole on the side of the collar will line up with the markings on the bottom of the part indicating the adjusters fully open or fully restricted state.


To determine the ideal setting for you, it is recommended to start with a balanced position in the middle of the adjustment range or to pick one of the presets above. Take note of how the forks respond during different riding conditions, such as on smooth roads, over bumps, during aggressive braking, or while cornering.

If you find the forks too harsh or stiff, try reducing the firmness by adjusting the settings towards a softer or more relaxed setting. Conversely, if you experience excessive movement or a lack of control, try increasing the firmness by adjusting the settings towards a firmer or more aggressive setting.

Ultimately, the perfect setting is subjective and depends on your personal preference, riding style, and the specific road and riding conditions you encounter. Experimenting with the adjustments and fine-tuning them over time will help you find the ideal balance that suits your needs.
