The Ohlins BM745 is an STX 36 rear twin shock solution for BMW R 1200 C, R 1200 C Independent, and R 850 C models. Built for improved chassis control and consistent damping, it is aimed at riders who want more composure and feedback from the rear suspension. The design uses a gas-pressurised damping system to help maintain stability across varying road conditions.

Ohlins | Made to race, perfected to ride

Ohlins road shocks draw on proven damping architecture to deliver predictable response and a controlled ride. The focus is on stability, traction and a clear connection between tyre and road, without making the bike feel harsh.

Who this shock is for

This rear twin shock setup suits riders who want a more controlled feel than standard suspension, particularly when loading the bike with a passenger or luggage, or when riding briskly on uneven surfaces. It is also a sensible choice if your current shocks are worn and you want a serviceable replacement with tuning flexibility.

Shock design & features

This is a gas-pressurised shock design to help reduce damping fade during longer rides. It uses separate damping circuits to better manage suspension movement over a range of inputs and supports a stable rear end under braking and through corners.

Tuning controls

The BM745 provides external damping adjustment for both compression and rebound, allowing you to balance comfort, grip and chassis attitude to suit your riding style. With independent control over these damping functions, you can address support under load separately from how quickly the shock returns after a bump.

Before you install

Confirm fitment for your exact model variant and ensure all mounting hardware and bushings are in good condition. After installation, set sag and check for adequate clearance through full suspension travel, then fine-tune damping once tyre pressures and load are finalised.

Serviceability/lifecycle

Ohlins shocks are designed to be serviced to maintain damping performance over time. Periodic servicing helps keep oil condition, seals and internal wear under control, which supports consistent feel and longevity.

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.
