The Ohlins BM423 STX 46 Adventure rear shock is built for the BMW F 650 Funduro, focusing on control and consistency when conditions get rough. It is intended to improve stability and comfort across long days, including corrugations and rocky climbs. Designed for adventure and touring use, it supports confidence and reduced rider fatigue on uneven surfaces.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a strong engineering focus on damping quality, durability and tuneability. For adventure riding, that means predictable behaviour over changing surfaces and load conditions. The STX 46 Adventure family targets real-world compliance without losing composure.

Who this shock is for

  • BMW F 650 Funduro riders who spend time on gravel, corrugations and broken backroads
  • Adventure and touring riders seeking steadier chassis control over long distances
  • Riders carrying luggage or occasionally riding with a pillion and wanting more stability

Shock design & features

This is a rear mono shock with a monotube-style architecture and an external reservoir for oil/gas separation to support damping consistency under demanding use. The STX 46 Adventure layout is aimed at maintaining composure when the shock is working hard, while keeping feedback clear at the tyre contact patch. Built for harsh conditions, it is designed to handle repeated impacts and sustained rough terrain.

Tuning controls

The BM423 includes external damping adjustment for rebound and compression, allowing you to tailor feel for terrain and load. It also includes spring preload adjustment to help set the bike’s ride height and balance for solo riding, luggage, or a pillion. These adjustments are intended to be practical for quick changes without disassembly.

Before you install

  • Confirm fitment for BMW F 650 Funduro and check clearance with any accessories fitted to the bike
  • Set spring preload to suit your typical load, then fine-tune rebound and compression to preference
  • After initial installation, re-check fasteners and settings once everything has bedded in

Serviceability/lifecycle

This Ohlins rear shock is serviceable and designed to be maintained over its working life. Periodic servicing helps keep damping performance consistent, especially for bikes used on dirt, in wet conditions, or over long-distance touring.

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.
