The Ohlins BM441 STX 46 Adventure rear shock is designed for BMW K 100 LT, K 100 RS, K 100 RT and K 75 models needing consistent suspension control across mixed road and touring conditions. Built around Ohlins’ STX architecture, it focuses on stability and composure when surfaces deteriorate or loads change. This unit is supplied as a rear mono shock for a direct-fit replacement.

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.

Öhlins Motorcycle Suspension Warranty

New Öhlins motorcycle shock absorbers, front forks and cartridge kits supplied by Teknik Motorsport are covered by the applicable Öhlins manufacturer’s warranty against defects in materials and workmanship.

Teknik Motorsport is an authorised Öhlins Service Centre and administers warranty claims in accordance with the Öhlins warranty conditions. The service intervals below form part of the maintenance requirements for Öhlins products supplied and supported by Teknik Motorsport.

This warranty is in addition to the consumer guarantees that apply under the Australian Consumer Law.

  • Registered motorcycles — non-competition road use Five years, subject to correct application, installation, setup and servicing every: 20,000 km or two years, whichever occurs first.
  • Registered motorcycles — adventure and light off-road use Five years, subject to correct application, spring rate, setup and servicing every: 10,000 km or annually, whichever occurs first.
  • Unregistered or competition motorcycles Two years for eligible Öhlins MX and Enduro products, subject to inspection every ten hours and servicing every: 30 operating hours or annually, whichever occurs first.

Compliance with the applicable service interval is a condition of the Öhlins manufacturer’s warranty. Evidence of servicing may be required when a warranty claim is assessed.

A seal leak, loss of damping performance or internal wear arising after the prescribed service interval has been exceeded will be treated as a service or maintenance issue rather than a manufacturing defect.

Warranty repairs

Öhlins suspension products are designed to be serviced and repaired. Where a warranty claim is approved, the normal remedy is repair of the customer’s original suspension unit using genuine Öhlins replacement parts.

Replacement of a complete shock absorber, fork or cartridge kit is not automatic and would normally occur only where the product has suffered a manufacturing failure that cannot reasonably be repaired. This is at Ohlins discretion. 

Öhlins spare parts and service kits

Öhlins spare parts, seals, bushes, service kits, springs, fluids and individual components are covered only against defects present when supplied.

No fixed age-based warranty applies to wear items, service parts or consumable components. Wear, deterioration, contamination, incorrect installation and damage caused by another component are not manufacturing defects.

Öhlins gives the customer a meaningful five-year warranty on products (Units), provided the suspension is maintained as suspension should be maintained. Teknik supports that warranty locally, can inspect the product properly, and can repair it with genuine parts rather than discarding it.
