The Ohlins STX 46 Blackline rear shock for the BMW R nineT is designed to improve chassis control and ride quality while keeping the bike’s classic feel intact. Built as a dedicated rear mono application, it provides a wide, usable tuning range for road riding. The Blackline finish suits factory and custom builds without drawing attention away from the bike.

Ohlins | Made to race, perfected to ride

Ohlins road shocks are developed around consistent damping behaviour and repeatable adjustment. The STX 46 platform is a proven design used across a wide range of street motorcycles, with serviceable internals and support for long-term ownership.

Who this shock is for

  • BMW R nineT riders wanting firmer, more controlled rear support without losing comfort.
  • Owners who carry a passenger or luggage and need practical preload adjustment.
  • Riders who like to fine-tune suspension feel for different roads and tyres.

Shock design & features

This shock uses a monotube layout with a separated gas and oil design for stable damping. It is built as a rear mono shock and is supplied with a black spring and matching Blackline body finish.

Tuning controls

  • Rebound damping adjustment to control how quickly the rear returns after a bump.
  • Compression damping adjustment to manage support and impact harshness.
  • Spring preload adjustment to set ride height and suit load changes.

Before you install

  • Confirm fitment for your exact BMW R nineT model and year, especially if replacing an earlier BM-series shock.
  • Set sag and preload first, then use compression and rebound adjustments to refine comfort and control.
  • If you are changing tyres or carrying extra load, revisit setup to keep the chassis balanced.

Serviceability/lifecycle

This Ohlins unit is fully serviceable, allowing oil and wear parts to be refreshed as needed. Routine servicing helps maintain consistent damping performance and extends component life, particularly if the bike is used regularly on rough roads.

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.
