The Ohlins BM492 STX 46 Blackline rear shock absorber is designed for the BMW R nineT Scrambler and R nineT Urban G/S. It brings modern damping control in a package that suits classic and custom builds, with a Blackline finish to match the bike’s styling. Built as a rear mono shock, it’s intended to improve stability and ride comfort while keeping the bike’s character intact.

Ohlins | Made to race, perfected to ride

Ohlins street shocks are developed with a focus on consistent damping and predictable chassis behaviour. The STX 46 Blackline family is aimed at riders who want a premium suspension feel with understated aesthetics.

Who this shock is for

  • BMW R nineT Scrambler and R nineT Urban G/S riders looking to refine comfort and control on the road
  • Owners building a vintage-inspired or custom look who want a Blackline finish
  • Riders who value adjustability to suit load, tyres, and riding style

Shock design & features

This is an STX 46 Blackline rear mono shock with a separated oil and gas design for stable damping behaviour over longer rides. The architecture is intended to maintain control and reduce fade compared with simpler emulsion-style layouts.

Tuning controls

The BM492 provides external adjustment for rebound damping, compression damping, and spring preload. These controls allow you to tailor the bike’s response to road conditions and rider/passenger or luggage changes without needing internal modifications.

Before you install

  • Confirm application fitment for your exact BMW R nineT Scrambler / Urban G/S model and year
  • Set sag and preload first, then fine-tune rebound and compression for balance and grip
  • Inspect linkage and mounting hardware condition during installation to ensure the shock can perform as intended

Serviceability/lifecycle

Ohlins shocks are designed to be serviceable, with internal components that can be maintained over time. Periodic servicing helps keep damping consistent and prolongs the working life of the unit.

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.
