The Ohlins BM505 rear shock is built for BMW R 1200 ST riders who want controlled, consistent suspension behaviour across mixed road conditions. Based on Ohlins STX architecture, it focuses on predictable damping and stable chassis support when the pace or load changes. It is supplied as a rear mono shock replacement suited to adventure-touring use.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a focus on damping control, traction, and repeatability. This unit is designed to deliver a composed feel and improved wheel control over changing surfaces without compromising long-distance comfort.

Who this shock is for

  • BMW R 1200 ST owners looking for a more controlled rear end for touring and rougher road conditions
  • Riders who value stability when carrying luggage or a pillion
  • Anyone wanting a quality rebuildable rear shock as a long-term serviceable solution

Shock design & features

This is an Ohlins STX 46 rear mono shock with oil/gas separated internal design to help keep damping consistent during extended use. The construction is intended for durability and stable performance across varied conditions.

Tuning controls

Adjustment is provided for rebound damping and spring preload, allowing you to tailor chassis attitude and rear wheel control to your load and riding conditions. These controls are intended to make it straightforward to refine feel after installation.

Before you install

  • Confirm fitment for BMW R 1200 ST and check general condition of linkage/bushings before installation
  • Set static and rider sag with the fitted spring and preload adjustment before changing damping
  • After initial rides, re-check fasteners and fine-tune rebound to suit your tyre choice and typical load

Serviceability/lifecycle

Like other Ohlins units, this shock is designed to be serviced to maintain performance over time. Periodic oil and seal refresh helps keep damping behaviour consistent, particularly with frequent long-distance or rough-road use.

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.
