The Ohlins BM147 TTX 36/TTX 39 Adventure shock is a front mono shock developed for BMW R 1200 GS (K50) and R 1250 GS models. It is aimed at improving control and consistency for adventure and touring use where surfaces and loads vary. This unit is designed to support long-distance riding and off-road conditions with stable, predictable damping.

Ohlins | Made to race, perfected to ride

Ohlins suspension is built around controlled damping behaviour and repeatability. On adventure platforms, that translates to steadier chassis attitude across mixed surfaces and reduced rider workload over long days.

Who this shock is for

  • Adventure and touring riders who want improved front-end control on corrugations, broken bitumen and rocky terrain
  • Riders who regularly carry luggage or ride two-up and need more stability under load
  • Owners looking for an Ohlins front mono shock solution for the listed BMW GS models

Shock design & features

This is an oil/gas separated design using the Ohlins TTX architecture from the TTX 36/TTX 39 Adventure family. The separated layout helps maintain damping consistency when conditions are harsh and use is prolonged.

Tuning controls

This shock includes external adjustment for rebound damping and compression damping, along with preload adjustment. These controls allow you to tailor support and wheel control for different terrain, pace and carried load.

Before you install

  • Confirm fitment for BMW R 1200 GS (K50) and BMW R 1250 GS as listed, and that you are replacing the front mono unit
  • Set sag and preload for your typical riding load before fine-tuning damping
  • Use clean practices during installation to protect seals and adjusters from contamination

Serviceability/lifecycle

Ohlins shocks are built to be serviceable. Regular servicing helps keep damping consistent and protects internal components, particularly for bikes used in dust, water crossings and sustained off-road conditions.
