The Ohlins BM506 STX 46 Adventure Shock Rear is a replacement rear shock absorber for the BMW R 1200 ST, designed for adventure and touring use. Built around Ohlins’ STX architecture, it’s intended to improve control and consistency when conditions and loads change. External adjusters allow practical tuning without dismantling the unit.

Ohlins | Made to race, perfected to ride

Ohlins suspension is engineered to deliver predictable damping behaviour and repeatable adjustments. This unit is part of the STX 46 Adventure family, aimed at riders who want stable handling and good compliance on mixed surfaces.

Who this shock is for

  • BMW R 1200 ST riders who tour, commute or ride on variable road surfaces
  • Riders who want added control and comfort on longer days in the saddle
  • Anyone who needs to tune the rear suspension for changing loads (solo vs luggage or pillion)

Shock design & features

This is a monotube shock with a separated gas and oil design for consistent damping and reduced fade during sustained use. The STX layout is built for durability and serviceability, suited to real-world adventure and touring conditions.

Tuning controls

The BM506 provides external damping adjustment for rebound and compression. Spring preload adjustment is also provided to help set ride height and support when load and riding conditions change.

Before you install

  • Confirm fitment for BMW R 1200 ST and rear mono position before installation
  • Set sag and preload first, then fine-tune rebound and compression to suit your tyres, load and road conditions
  • Plan periodic servicing to keep damping performance consistent over time
