The Ohlins BM508 rear shock is built for the BMW R 1200 GS with a focus on controlled damping and consistent ride feel across mixed surfaces. Designed for adventure and touring use, it supports stability when conditions change from smooth roads to rough tracks. The STX 46 architecture is aimed at maintaining composure and traction without compromising day-long comfort.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a racing engineering mindset and adapted for real-world riding. The goal is predictable response, clear feedback and dependable performance across a wide range of environments typical of an adventure bike.

Who this shock is for

  • BMW R 1200 GS riders who want improved control and comfort for adventure and touring use
  • Riders regularly encountering corrugations, rocky sections and uneven terrain
  • Those looking for stable behaviour when carrying luggage or a pillion

Shock design & features

This is an STX 46 rear mono shock. It uses an oil/gas separated design for more consistent damping control during demanding use. The assembly is intended to handle harsh conditions while keeping the rear end settled and planted.

Tuning controls

The BM508 includes external adjusters to tailor the damping behaviour to your riding conditions. It provides rebound damping adjustment, compression damping adjustment, and a remote hydraulic preload adjuster to help compensate for changes in load and ride height feel.

Before you install

  • Confirm fitment for BMW R 1200 GS and your model year before installation
  • Set sag and preload for your typical load (solo, luggage, or pillion) before fine-tuning damping
  • If your bike has been lowered/raised or heavily modified, check clearances and travel limits

Serviceability/lifecycle

This Ohlins unit is designed to be serviceable, with routine maintenance helping preserve damping consistency over time. Keeping the shock clean and addressing leaks or performance changes early will help extend service life.

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.
