The Ohlins BM445 STX 46 Street rear shock is built for BMW K 1200 R, K 1200 R Sport and K 1200 S riders who want a more controlled, composed ride on the road. Based on Ohlins street-focused STX architecture, it is designed to deliver consistent damping feel and clear chassis feedback. This unit is a rear mono shock suited to riders who value stability, traction and tuneability.

Ohlins | Made to race, perfected to ride

Ohlins brings race-developed damping knowledge into a street application with practical adjustment and durable construction. The STX 46 Street family is aimed at improving control and confidence without sacrificing everyday ride quality.

Who this shock is for

Ideal for riders using their K 1200 on spirited road rides, commuting, or regular weekend runs where consistency and stability matter. It suits anyone looking to refine rear-end support and tyre contact through corners and under braking, while keeping the bike predictable over varying road surfaces.

Shock design & features

This is an oil/gas separated design, using a pressurised system to help maintain stable damping behaviour through longer rides. The STX 46 Street construction is intended to provide strong control with smooth response, supporting better chassis balance for street conditions.

Tuning controls

The BM445 provides rebound damping adjustment, allowing you to tailor how quickly the rear recovers after bumps and weight transfer. This helps you fine-tune stability, grip and overall ride feel to match your load, tyres and riding pace.

Before you install

Confirm fitment for your exact model and year within the BMW K 1200 R, K 1200 R Sport and K 1200 S range. After installation, set sag correctly and then adjust rebound in small steps to suit your roads and riding style. If you ride with a passenger or luggage, re-check your settings to keep the chassis balanced.

Serviceability/lifecycle

As an Ohlins unit, the shock is designed to be serviceable, with periodic maintenance helping maintain damping consistency over time. Regular inspection and scheduled servicing are recommended, especially if the bike is used year-round or on rougher 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.
