The Ohlins BM908 is a rear STX 46 shock absorber built for the BMW K 1300 GT, aimed at improving control and consistency across varied road conditions and touring loads. It uses a separated oil/gas design to help maintain damping stability over longer rides. External adjusters let you tailor the feel without disassembly, making it practical for riders who change loads or riding pace.

Ohlins | Made to race, perfected to ride

Ohlins suspension units are designed around predictable damping behaviour and repeatable tuning. For the K 1300 GT, the focus is on maintaining composure under braking and acceleration while keeping the chassis settled with luggage or a pillion.

Who this shock is for

  • BMW K 1300 GT riders wanting more controlled rear suspension response for sport-touring use
  • Riders who regularly vary load (solo, luggage, pillion) and want straightforward adjustment
  • Owners looking for a serviceable premium replacement rear mono shock

Shock design & features

This is an STX 46 rear mono shock with a separated oil/gas layout, intended to support consistent damping during sustained use. The architecture is designed to manage heat and reduce fade compared with simpler designs, helping the bike stay composed on longer rides.

Tuning controls

The BM908 provides external rebound damping adjustment and external compression damping adjustment. It also includes spring preload adjustment to suit different rider weights and carrying loads.

Before you install

  • Confirm fitment for BMW K 1300 GT and rear mono shock application before purchase
  • Set sag and preload for your typical load, then fine-tune rebound and compression to match your roads and riding style
  • After installation, re-check fasteners and settings after the first few rides

Serviceability/lifecycle

As an Ohlins unit, the BM908 is designed to be maintained and serviced to keep performance consistent over time. Regular servicing helps preserve damping quality, particularly for riders covering high kilometres or carrying heavier touring loads.

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.
