The Ohlins BM931 TTX RT rear shock is built for BMW S 1000 RR riders chasing accurate chassis control and consistent damping. Based on Ohlins TTX architecture, it is aimed at riders who tune for feel and repeatability rather than a one-size-fits-all setting. The design focuses on stable traction and clear feedback under demanding riding.

Ohlins | Made to race, perfected to ride

TTX RT is part of Ohlins’ track-focused range, developed from competition experience and adapted for high-performance road and circuit use. The intent is predictable behaviour through corners and under load changes, with adjustments that allow you to match the shock to your tyres, pace and conditions.

Who this shock is for

This rear mono shock suits riders who regularly ride hard on the road or attend track days and want more control over rear grip and chassis attitude. It is also a strong option if you want a broader tuning window to dial in comfort, support and drive on corner exit.

Shock design & features

This model uses an oil/gas separated, gas-pressurised damping system to help maintain damping consistency as temperatures and loads rise. The TTX-style layout is designed to provide stable damping performance and a direct connection between adjustment changes and on-bike feel.

Tuning controls

The BM931 provides external damping adjustments for compression and rebound, allowing you to balance bump absorption with support and manage how quickly the shock returns after being compressed. Spring preload adjustment is also provided to set ride height and sag for rider weight and usage.

Before you install

• Confirm fitment for your exact BMW S 1000 RR variant and model year before installation.
• Set sag and preload first, then fine-tune rebound and compression one change at a time.
• After installation, re-check fasteners and clearances after the first ride.

Serviceability/lifecycle

Ohlins shocks are designed to be serviced and re-valved as needed, helping maintain performance over time. Regular servicing is recommended, particularly if the bike sees track use or sustained hard riding.
