The Ohlins BM345 TTX GP rear shock is a dedicated rear mono shock for the BMW S 1000 R, developed from Ohlins race suspension architecture. It is built around consistent damping control and clear chassis feedback when riding at higher loads. This unit uses a separated oil and gas design to help maintain stable damping through longer sessions.

Ohlins | Made to race, perfected to ride

TTX GP sits at the sharp end of the Ohlins road-and-track range, focusing on predictable response and adjustment range rather than comfort-focused compromise. It is intended for riders who want to tune chassis balance accurately and repeatably.

Who this shock is for

Suited to riders using the BMW S 1000 R for trackdays, fast road riding, or competition where traction and stability matter most. It is also a good match if you already understand sag and damping changes and want suspension that responds clearly to adjustments.

Shock design & features

This is an Ohlins TTX GP rear mono shock using a separated oil and gas layout to improve consistency. The damping architecture is designed to give stable support under braking and acceleration while maintaining tyre contact over surface changes.

Tuning controls

The BM345 provides external damping adjustment for both rebound and compression, allowing you to tailor behaviour for different tyres, surfaces, and riding styles. It also includes ride height adjustment to help fine-tune chassis geometry and weight transfer.

Before you install

Set sag first, then make damping changes one at a time so you can feel cause and effect. If your bike has been modified for weight, tyres, or regular track use, confirm the spring choice and baseline settings during installation.

Serviceability/lifecycle

Like all high-performance Ohlins shocks, the BM345 is designed to be serviced to restore damping performance and seal integrity over time. Regular servicing helps maintain consistent feel and protects internal components, particularly when used on track.
