This premium, fully adjustable cartridge system replaces the stock Showa Dual Bending Valve internals, utilizing Öhlins’ patented NIX technology to deliver unparalleled stability, cornering precision, and rider confidence on the M8 Softail chassis.
NIX Technology: Precision Damping Control

The NIX (Needle & Independent X-Damping) system provides a level of tuning precision and control far beyond stock components.

Independent Damping Circuits: The key feature of NIX is the separation of the damping circuits: compression damping is handled by one fork leg, and rebound damping is handled by the other. This prevents interaction between the two adjustments, allowing for extremely accurate and predictable tuning.

Fully Adjustable Externally: The top of each fork cap features easily accessible external adjusters for:

Compression Damping

Rebound Damping

Spring Preload This provides the rider with the ability to precisely dial in the bike’s front-end response for various loads, roads, and riding styles.

Superior Stability: The controlled damping virtually eliminates the harshness and instability often experienced with the stock setup. It dramatically reduces front-end dive under heavy braking and pitch when cornering, providing a more planted and confident feel.
