The Ohlins BM148 TTX 36/TTX 39 Adventure rear shock is developed for BMW GS Adventure and Rallye models where stability and control matter across mixed surfaces. Built around the TTX twin-tube architecture, it is designed to deliver consistent damping over long distances and variable conditions. It is intended to support confident chassis behaviour when the load and terrain change during a ride.

Ohlins | Made to race, perfected to ride

Ohlins TTX Adventure shocks are engineered for riders who want predictable response and repeatable tuning. The TTX design helps maintain damping control as temperatures and surface inputs vary, making it well suited to adventure and touring use.

Who this shock is for

  • Adventure and touring riders chasing stable handling on bitumen, gravel and corrugations
  • Riders who regularly change load (luggage or pillion) and want easier setup changes
  • Owners upgrading from standard suspension to gain a broader tuning range

Shock design & features

This is a rear mono shock from the Ohlins TTX 36/TTX 39 Adventure family. The TTX twin-tube layout uses separated oil and gas to support consistent damping behaviour and control under repeated impacts.

Tuning controls

The BM148 provides external adjustments for rebound damping and compression damping, along with spring preload adjustment. These controls allow you to balance comfort, traction and chassis support to suit terrain and load.

Before you install

This application is listed with a note that water-cooled ESA versions can show a warning light in the display, which does not affect the bike’s performance. Confirm model and configuration before fitment, and check that your intended use (load and riding conditions) matches the supplied spring and adjustment range.
