The Ohlins YA506 STX 46 Street rear shock is a direct replacement unit for the Yamaha TDM 900, built to improve chassis control and ride quality on the road. It uses Ohlins damping architecture developed from their long-running suspension programs, with a focus on predictable grip and composure. This is a rear mono shock designed to give you a broader, more usable tuning range than standard equipment.

Ohlins | Made to race, perfected to ride

STX 46 Street shocks are designed to deliver consistent damping behaviour and clear feedback at the tyre contact patch. The YA506 is intended for street use where stability, comfort and controlled body movement matter as much as outright performance.

Shock design & features

  • 46-series monotube shock layout built for controlled damping and consistent response.
  • Oil and gas separated design to help maintain damping stability as conditions change.
  • Road-focused STX 46 Street configuration suited to everyday riding and touring loads.

Tuning controls

  • Rebound damping adjustment to control how quickly the shock extends after compression.
  • Spring preload adjustment to set ride height and support for rider, luggage, or passenger use.

Base setup (factory preset)

This unit is supplied with an Ohlins baseline setting intended to work as a starting point on the TDM 900. From there, small changes to preload and rebound can be used to match load, tyre choice and road conditions.

Before you install

  • Confirm all mounting hardware condition and torque requirements during fitment.
  • Set sag with preload before chasing damping changes.
  • After installation, re-check fasteners and settings once the shock has bedded in.

Serviceability/lifecycle

As a serviceable Ohlins unit, the YA506 can be maintained with periodic oil and wear-part replacement to keep damping performance consistent over time. Regular servicing is especially important if the bike is used year-round or on rough roads.
