The Ohlins BM318 STX 46 Adventure Shock Rear is a rear mono shock for the BMW K 1200 GT, built for stable, controlled suspension behaviour in adventure and touring use. It uses a separated oil/gas layout to help maintain damping consistency when conditions and loads change. This unit is designed to support long-distance comfort while keeping the chassis settled across mixed surfaces.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a focus on repeatable damping behaviour and practical adjustability. For riders who want a dependable setup that can be tuned to suit different roads and loads, this rear shock provides a solid platform without overcomplication.

Who this shock is for

• BMW K 1200 GT riders covering long distances who want more control and comfort from the rear end
• Touring riders who vary luggage and pillion loads and need a shock that can be adjusted accordingly
• Riders who encounter rougher surfaces and want a more composed, planted feel

Shock design & features

This is an STX 46 Adventure-series rear shock using a separated oil/gas design rather than an emulsion format. The architecture is intended to reduce fade and keep damping more consistent during extended rides, especially when the shock is working harder.

Tuning controls

The BM318 includes external adjustment for rebound damping and compression damping, allowing you to fine-tune how quickly the shock extends and how it resists compression under bumps and load transfer. It also includes spring preload adjustment to set ride height and support for rider weight, luggage, and pillion use.

Before you install

• Set sag and preload first, then refine rebound and compression to suit your roads and loading
• Check clearances and routing around the shock body and reservoir/hose arrangement during installation
• If you regularly alternate between solo and loaded touring, note your settings so you can return to a known baseline

Serviceability / lifecycle

As a serviceable Ohlins unit, the shock can be maintained over its life to keep performance consistent. Regular inspection and periodic servicing helps preserve damping quality, seal condition, and overall reliability for long-term adventure and touring use.
