The Ohlins BM137 STX 46 Adventure rear shock is designed for BMW K 100 LT, K 100 RS, K 100 RT and K 75 models needing consistent control for touring and mixed-surface use. Built around Ohlins’ STX architecture, it focuses on stable damping behaviour over long days and varying loads. External adjustment lets you tailor the feel without disassembly.

Ohlins | Made to race, perfected to ride

Ohlins suspension components are developed with a focus on damping control, durability and repeatable tuning. This unit is intended to provide predictable support and comfort across changing road conditions and ride demands.

Who this shock is for

Suited to riders using their K-series BMW for adventure-touring, commuting and long-distance riding where surface quality can vary. It’s also appropriate if you regularly ride with luggage or a pillion and want a rear end that stays composed and planted.

Shock design & features

This is a rear mono shock using a gas-separated design for more consistent damping performance during sustained use. The STX body design is aimed at maintaining control and comfort over extended rides while remaining robust for demanding conditions.

Tuning controls

Adjustment is provided for rebound damping and compression damping, along with spring preload. These controls allow you to balance comfort, support and stability depending on load and terrain.

Before you install

  • Confirm model fitment: BMW K 100 LT, K 100 RS, K 100 RT and K 75.
  • Set spring preload for your typical load before fine-tuning damping.
  • After installation, re-check fastener torque and clearance through suspension travel.

Serviceability / lifecycle

Like other Ohlins units, this shock is designed to be serviced to maintain performance over time. Periodic inspection and servicing helps keep damping consistent and protects internal components, especially with frequent touring or rough-road use.
