The Ohlins BM203 STX 46 Adventure rear shock is built to improve control, comfort and consistency on classic BMW R-series models used for adventure and touring. It is designed to better manage varying loads and surface changes while maintaining predictable chassis behaviour. This unit is supplied as a complete rear shock replacement for twin-shock applications.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a focus on stable damping performance and reliable adjustment for real-world riding conditions. The STX Adventure family is aimed at riders who mix sealed and unsealed roads and want a more controlled, less fatiguing ride over long distances.

Who this shock is for

  • Riders using their BMW R-series for touring, commuting and light adventure duty
  • Owners carrying luggage or a pillion who want steadier ride height and control
  • Those chasing improved composure over rougher surfaces without sacrificing comfort

Shock design & features

This is an Ohlins STX 46 Adventure rear shock for twin-shock fitment. It uses a separated oil/gas design to help maintain damping consistency as conditions and temperatures change, and is intended to deliver controlled movement through repeated bumps and corrugations.

Tuning controls

This shock includes external adjustment to support practical, on-bike tuning for changing loads and road conditions. Use the adjusters to balance comfort, control and stability to suit your bike setup and riding environment.

Before you install

  • Confirm fitment for your exact BMW model and year, and that your bike uses a twin rear shock arrangement
  • Inspect mounting hardware and bushes, replacing worn components during installation
  • After installation, re-check fasteners and alignment once the suspension has settled

Serviceability / lifecycle

Ohlins shocks are serviceable and can be maintained to keep performance consistent over time. Regular inspection and periodic servicing will help preserve damping quality, especially for bikes used on rough roads and long trips.

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.
