The Ohlins BM908 is a rear STX 46 shock absorber built for the BMW K 1300 GT, aimed at improving control and consistency across varied road conditions and touring loads. It uses a separated oil/gas design to help maintain damping stability over longer rides. External adjusters let you tailor the feel without disassembly, making it practical for riders who change loads or riding pace.

Ohlins | Made to race, perfected to ride

Ohlins suspension units are designed around predictable damping behaviour and repeatable tuning. For the K 1300 GT, the focus is on maintaining composure under braking and acceleration while keeping the chassis settled with luggage or a pillion.

Who this shock is for

  • BMW K 1300 GT riders wanting more controlled rear suspension response for sport-touring use
  • Riders who regularly vary load (solo, luggage, pillion) and want straightforward adjustment
  • Owners looking for a serviceable premium replacement rear mono shock

Shock design & features

This is an STX 46 rear mono shock with a separated oil/gas layout, intended to support consistent damping during sustained use. The architecture is designed to manage heat and reduce fade compared with simpler designs, helping the bike stay composed on longer rides.

Tuning controls

The BM908 provides external rebound damping adjustment and external compression damping adjustment. It also includes spring preload adjustment to suit different rider weights and carrying loads.

Before you install

  • Confirm fitment for BMW K 1300 GT and rear mono shock application before purchase
  • Set sag and preload for your typical load, then fine-tune rebound and compression to match your roads and riding style
  • After installation, re-check fasteners and settings after the first few rides

Serviceability/lifecycle

As an Ohlins unit, the BM908 is designed to be maintained and serviced to keep performance consistent over time. Regular servicing helps preserve damping quality, particularly for riders covering high kilometres or carrying heavier touring loads.
