The Ohlins BM688 STX 46 Adventure rear shock is purpose-built for the BMW HP 2 Enduro, focusing on control and consistency on rough surfaces. It is designed to maintain stability and rider comfort over long distances, including when the bike is carrying extra load. External adjusters make it practical to refine the feel to suit changing terrain.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a clear focus on predictable damping and durability in demanding conditions. This unit is part of the STX 46 Adventure family, intended for adventure and touring use where terrain and loads can vary widely.

Who this shock is for

  • BMW HP 2 Enduro riders spending time on corrugations, rocky climbs, and mixed off-road terrain
  • Adventure and touring riders who want a more controlled rear end over distance
  • Owners needing stable behaviour when adding luggage or a pillion

Shock design & features

This is a rear mono shock using an oil/gas separated design to help keep damping consistent under sustained off-road use. The STX architecture is aimed at stability and comfort without sacrificing feedback when the pace picks up.

Tuning controls

Adjustment is provided for compression damping, rebound damping, and spring preload. These external controls let you tailor the shock to suit terrain changes, rider preference, and load carried.

Before you install

  • Confirm the shock is being fitted to a BMW HP 2 Enduro and that mounting hardware is correct for your bike
  • Set sag and preload for your typical riding load before fine-tuning damping
  • After installation, recheck fasteners and clearances through the suspension travel

Serviceability/lifecycle

As a rebuildable Ohlins unit, the BM688 is intended to be serviced to maintain performance over time. Regular inspection and periodic servicing will help keep damping consistent, especially if the bike sees frequent dust, water crossings, or long off-road days.
