The Ohlins BM509 STX 46 Adventure front shock is built for BMW R 1200 GS riders who want more control and composure when conditions turn rough. Designed for adventure and touring use, it supports consistent damping performance across changing surfaces and loads. It is a front mono shock supplied as a complete unit with spring fitted.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a focus on damping control, stability and reliability. For adventure bikes, that means predictable feedback on corrugations, broken bitumen and technical tracks, without sacrificing comfort on longer days.

Who this shock is for

  • BMW R 1200 GS owners chasing improved front-end control for mixed touring and off-road riding
  • Riders carrying luggage or changing load often and wanting a more stable, tuneable front setup
  • Anyone replacing a tired original shock with a purpose-built adventure unit

Shock design & features

This is an Ohlins STX 46 Adventure-series mono shock for the front position. It uses an oil/gas separated internal design to help maintain consistent damping behaviour on extended, rough rides. The unit is supplied with a spring installed from the factory.

Tuning controls

External adjustment is provided for rebound damping, allowing you to fine-tune how quickly the shock returns after compressing. Spring preload adjustment is also provided to help suit rider weight and typical load, keeping ride height and balance where you want it.

Before you install

  • Confirm fitment for your exact BMW R 1200 GS model and year, as this listing is for a front mono configuration
  • After installation, set preload first, then refine rebound damping to match your tyres, terrain and load
  • Check clearances and fastener torque as per the motorcycle service manual

Serviceability / lifecycle

Ohlins shocks are designed to be serviceable. Periodic inspection and servicing helps keep damping performance consistent, particularly for adventure riding where dirt, water crossings and corrugations increase wear on seals and oil.

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.
