The Ohlins BM147 TTX 36/TTX 39 Adventure shock is a front mono shock developed for BMW R 1200 GS (K50) and R 1250 GS models. It is aimed at improving control and consistency for adventure and touring use where surfaces and loads vary. This unit is designed to support long-distance riding and off-road conditions with stable, predictable damping.

Ohlins | Made to race, perfected to ride

Ohlins suspension is built around controlled damping behaviour and repeatability. On adventure platforms, that translates to steadier chassis attitude across mixed surfaces and reduced rider workload over long days.

Who this shock is for

  • Adventure and touring riders who want improved front-end control on corrugations, broken bitumen and rocky terrain
  • Riders who regularly carry luggage or ride two-up and need more stability under load
  • Owners looking for an Ohlins front mono shock solution for the listed BMW GS models

Shock design & features

This is an oil/gas separated design using the Ohlins TTX architecture from the TTX 36/TTX 39 Adventure family. The separated layout helps maintain damping consistency when conditions are harsh and use is prolonged.

Tuning controls

This shock includes external adjustment for rebound damping and compression damping, along with preload adjustment. These controls allow you to tailor support and wheel control for different terrain, pace and carried load.

Before you install

  • Confirm fitment for BMW R 1200 GS (K50) and BMW R 1250 GS as listed, and that you are replacing the front mono unit
  • Set sag and preload for your typical riding load before fine-tuning damping
  • Use clean practices during installation to protect seals and adjusters from contamination

Serviceability/lifecycle

Ohlins shocks are built to be serviceable. Regular servicing helps keep damping consistent and protects internal components, particularly for bikes used in dust, water crossings and sustained off-road conditions.

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.
