The Ohlins BM358 TTX RT rear shock is built for BMW S 1000 RR riders chasing repeatable control and clear chassis feedback. Based on Ohlins racing development, it focuses on stable damping behaviour and consistent traction when you start pushing harder. It is a gas-pressurised design intended to keep performance steady as conditions and pace change.

Ohlins | Made to race, perfected to ride

TTX RT is Ohlins' track-focused rear shock line, developed around balanced damping control and strong feel at the tyre contact patch. The intent is predictable support on the brakes and confidence driving out of corners, without making the bike feel vague or inconsistent.

Shock design & features

  • Rear mono shock application for the BMW S 1000 RR (not for HP4).
  • Gas-pressurised damping system for consistent behaviour during demanding riding.
  • Independent damping circuits aimed at maintaining control through braking, corner entry, and corner exit.

Tuning controls

This shock provides external damping adjustment for both compression and rebound, allowing you to tailor support and response to your tyres, track surface, and riding style. Adjustment access is designed to support practical tuning between sessions rather than requiring internal revalving for routine changes.

Base setup (factory preset)

The BM358 is supplied with an Ohlins baseline tune to suit the intended bike fitment. From there, fine tuning is typically done with damping adjustments to balance grip, stability, and feedback to match your load, tyres, and pace.

Before you install

  • Confirm model compatibility: this unit is specified as not for HP4.
  • Check linkage, bearings, and mounting hardware condition to avoid masking suspension gains with worn components.
  • Set sag and verify free movement through the swingarm/linkage range before chasing damping changes.

Serviceability/lifecycle

As a high-performance, gas-pressurised race-derived shock, it benefits from regular servicing to keep damping consistent and protect internal components. Routine maintenance helps preserve performance and makes setup changes more meaningful over time.
