The Ohlins TR420 STX 46 Street rear shock is a model-specific upgrade for the Triumph Scrambler 400X, built around proven Ohlins damping architecture for controlled road performance. It is a gas-pressurised, oil/gas separated design intended to keep damping consistent as conditions change. Adjustment is provided for rebound and compression, along with preload to suit rider load and ride feel.

Ohlins | Made to race, perfected to ride

STX 46 Street units are developed to deliver predictable chassis behaviour and clearer feedback on sealed roads. The focus is on stability and control without compromising everyday usability.

Shock design & features

  • Rear mono shock configuration for the Scrambler 400X application
  • Gas-pressurised damping with oil/gas separation to help maintain consistent behaviour
  • Ohlins valving approach aimed at traction and stability through changing road surfaces

Tuning controls

  • Rebound damping adjustment
  • Compression damping adjustment
  • Spring preload adjustment

Base setup (factory preset)

The shock is supplied with a fitted spring and an Ohlins baseline setting to suit the intended model fitment. From there, rebound, compression and preload can be tailored to rider weight, luggage and preferred ride feel.

Before you install

  • Fitment note: does not fit Speed 400
  • Confirm access to the adjusters on your bike before finalising hose/clearance and routing around adjacent components
  • Plan a basic sag check after installation so preload and damping adjustments start from a known baseline

Serviceability/lifecycle

This is a rebuildable Ohlins unit designed to be serviced to maintain performance over time. Using the recommended Ohlins oil helps keep damping characteristics consistent between services.
