The Ohlins BM450 STX 46 Street rear shock is built for the BMW R nineT, focusing on controlled damping and clear feedback for real-world road riding. It uses a gas-pressurised design to help maintain consistent performance as conditions and pace change. The result is a more settled chassis and improved confidence through corners and under braking.

Ohlins | Made to race, perfected to ride

Developed from Ohlins race program experience, the STX 46 Street platform is aimed at riders who want higher quality damping control without losing everyday usability. It is intended as a direct-fit rear mono shock replacement for the R nineT.

Shock design & features

  • STX 46 Street rear mono shock for BMW R nineT
  • Gas-pressurised damping architecture for consistent response
  • Valving developed to improve traction and chassis stability

Tuning controls

This rear shock provides external damping adjustments for both compression and rebound, allowing you to fine-tune support under braking and acceleration as well as ride comfort over rough surfaces.

Is it right for you?

It suits riders who want clearer front-to-rear balance, more composed handling, and the ability to tailor damping to load and riding style. If you regularly change between solo riding and carrying luggage, or you’re chasing more consistency in faster road riding, the added adjustability is particularly useful.

Before you install

Confirm fitment for your exact BMW R nineT model and year, and note this unit replaces BM 440. After installation, set sag and check clearances through full suspension travel before road testing.

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.
