The Ohlins TR821 STX 36 Street rear shock is built to improve chassis control and damping consistency on the Triumph Speedmaster. It’s designed to deliver clear feedback at the rear tyre, helping the bike stay composed through changing road conditions. Adjustment is provided so you can tailor the feel to your preference without changing the core hardware.

Ohlins | Made to race, perfected to ride

STX 36 Street shocks apply Ohlins damping know-how in a road-focused package. The design targets predictable behaviour and repeatable setup changes, supporting stable handling and confidence across everyday riding and spirited use.

Shock design & features

This is a monotube shock with an internal gas pressurisation design (emulsion architecture). The layout is intended to keep damping behaviour consistent and responsive, with the STX 36 platform built around controlled oil flow through the damping system.

Tuning controls

  • Rebound damping adjustment to fine-tune how quickly the shock extends after compression.

Who this shock is for

Suited to Speedmaster riders who want a more controlled rear end and the ability to tune rebound to match load, road surfaces, and personal preference. It’s also a sensible choice if your current shock feels underdamped, unsettled, or inconsistent over bumps.

Before you install

  • Confirm fitment for your exact Triumph Speedmaster model and year before installation.
  • Set sag correctly and start with a balanced rebound setting before making further changes.
  • Inspect linkage and mounting hardware condition during installation.

Serviceability/lifecycle

As an Ohlins unit, this shock is designed to be maintained and re-serviced over its life. Periodic servicing helps keep damping performance consistent and protects internal components as oil and seals age.
