TFX Suspension Technology, No standard!

Unlock the full potential of your motorcycle with the TFX The Xtreme + HPA (1423MSSF). Engineered for those who demand the competitive edge, this rear shock absorber features a high-capacity piggyback reservoir and our convenient Hydraulic Preload Adjuster, delivering race suspension performance that adapts instantly to the track or the street.

Built for ultra-high performance! This piggyback shock is designed for the rider who seeks the highest levels of durability, control, and refined tuning options. It doesn’t matter if you use it for Adventure riding, Baja racing, or track day suspension—this shock is a winner!

Every TFX shock has a damping valving specifically developed for its application, and the spring is selected for your weight and intended use. Our modular assembly system allows us to make special requirements (like different spring or anodizing color) or changes in length as a second nature.

The upper mount consists of a full CNC-milled aluminum 7075 part. It serves as a connection to the external reservoir which gives the shock extra cooling for superior thermal stability and houses the setup screws for the high- and low-speed compression adjustment.

It features a 3-way adjustable independent damping system: rebound adjustment, low-speed compression, and high-speed compression. This gives you the ability to fine-tune your rear suspension with absolute precision. With the included Hydraulic Preload Adjuster, you can set the spring preload for extra loading instantly—no C-spanner required.
