Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a strong engineering focus on damping control, durability and repeatable performance. The STX 46 Adventure family is aimed at riders who want reliable behaviour over long distances, with the support to suit varying conditions and loads.

Who this shock is for

• Riders refreshing aging suspension on BMW K-series models for more controlled, predictable handling
• Touring riders who regularly ride with luggage or a pillion and want easier load management
• Owners seeking an Ohlins rear mono shock solution suited to adventure-touring style use

Shock design & features

This is an oil/gas separated rear shock design, intended to deliver consistent damping behaviour during extended riding. The construction is aimed at maintaining stability and comfort when the bike is working harder over rougher surfaces.

Tuning controls

This shock includes external damping adjustment for rebound and compression, allowing you to tailor response for road conditions and riding style. It also includes an external preload adjuster to help compensate for changes in load.

Before you install

• Confirm application for BMW K 100 LT, K 100 RS, K 100 RT and K 75, and verify fitment against your exact model and year
• Set sag and preload for your typical load, then fine-tune rebound and compression to suit your roads and pace
• This part has been noted as replaced by BM 137; confirm which unit you require before ordering

Serviceability / lifecycle

Ohlins shocks are designed to be serviceable, supporting long-term ownership through inspection and scheduled maintenance. Periodic servicing helps maintain damping consistency and seal life, particularly for bikes used in harsher conditions or with frequent load changes.
