The Ohlins BM641 STX 46 Street rear shock is built for BMW R nineT Scrambler and R nineT Urban G/S riders who want more controlled damping and clearer chassis feedback on the road. It is a gas-pressurised mono shock with separated oil and gas to help maintain consistent damping as conditions change. Designed as a bolt-on replacement, it focuses on predictable support and tunability rather than harshness.

Ohlins | Made to race, perfected to ride

Ohlins road products draw on proven internal designs and damping principles developed through competition and refined for everyday use. The STX 46 Street platform is aimed at improving stability, traction and rider confidence across real-world surfaces.

Who this shock is for

Suited to riders who use their R nineT on the street and want a more composed rear end during braking, corner entry and acceleration. It is also a good match if you regularly ride with varying loads and want a shock that can be adjusted to suit.

Shock design & features

This is a rear mono shock from the Ohlins STX 46 Street family. It uses a gas-pressurised design with separated oil and gas, supporting consistent damping behaviour over a wide range of riding conditions.

Tuning controls

Adjustability includes rebound damping control to fine-tune how the shock extends after compression. Spring preload adjustment is provided to set ride height and balance for rider weight and loading.

Before you install

  • Confirm fitment for your exact model and year; noted as not fitting model year 2021.
  • Inspect linkage and mounting hardware condition before installation.
  • After installation, set sag and verify clearance through full suspension travel.

Serviceability/lifecycle

Like other Ohlins units, this shock is designed to be maintained with periodic servicing to keep damping performance consistent. Regular inspection and oil service help preserve internal components and ride quality over time.

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.
