The Ohlins BM340 TTX GP rear shock is a track-focused unit for the BMW S 1000 RR. Built around Ohlins’ TTX architecture, it’s aimed at delivering consistent damping behaviour and clear chassis feedback under hard use. This is a dedicated rear mono shock designed for riders who want dependable adjustability for circuit tuning.

Ohlins | Made to race, perfected to ride

BM340 is part of the Ohlins TTX GP family, developed from competition experience and intended for precise suspension control on track. It suits riders prioritising stability, traction and repeatable performance across a session.

Who this shock is for

  • BMW S 1000 RR riders setting up primarily for track days and racing
  • Riders who want a wider tuning window to suit tyres, pace and circuits
  • Those chasing clearer rear-end feel during braking, turn-in and corner exit

Shock design & features

This is a gas-pressurised design with oil and gas separation to help maintain damping consistency during sustained, high-load riding. The TTX layout is engineered to deliver predictable response through the stroke, supporting chassis balance under aggressive inputs.

Tuning controls

The BM340 provides external damping adjustments for both compression and rebound, allowing you to tune support under braking and acceleration separately from recovery control. This makes it well suited to systematic track setup changes as conditions, tyres and riding style evolve.

Before you install

  • Confirm application: listed for BMW S 1000 RR (note: not HP4).
  • Check clearance and linkage condition, and ensure bearings and fasteners are in good order before fitting.
  • After installation, set sag and baseline damping to suit your weight and intended track use.

Serviceability / lifecycle

As a rebuildable Ohlins unit, the BM340 is intended to be serviced to maintain performance over time. Regular inspection and oil service intervals should be based on track hours and operating conditions.
