The Ohlins BM689 STX 46 Street rear shock is built to deliver controlled damping and clear chassis feedback for road riding. Developed from Ohlins suspension know-how, it’s designed as a direct-fit rear mono shock for the BMW Megamoto. The STX architecture helps maintain consistent damping behaviour across a wide range of conditions.

Ohlins | Made to race, perfected to ride

Ohlins street suspension focuses on predictable support, grip and ride quality. This unit is part of the STX 46 Street family and is intended for riders who value stability and tunability without compromising everyday usability.

Shock design & features

  • STX-style rear mono shock design for the BMW Megamoto
  • Oil and gas separated damping system to help reduce aeration and maintain consistency
  • Purpose-built fitment to suit the motorcycle’s linkage and mounting layout

Tuning controls

This shock provides external adjustment for rebound damping and compression damping, allowing you to tailor support and control to your tyres, load and preferred feel.

Base setup (factory preset)

The shock is supplied with an Ohlins baseline setting intended as a starting point for street use. From there, adjust in small steps to match your road conditions and riding style.

Before you install

  • Confirm correct model fitment for your BMW Megamoto and check clearance at full suspension travel.
  • Inspect mounting hardware and bearings/bushes and replace any worn parts during installation.
  • After installation, set sag and then fine-tune damping to suit your usual riding conditions.

Serviceability/lifecycle

As with other Ohlins units, this shock is designed to be maintained and serviced over its life. Regular servicing helps keep damping performance consistent and protects internal components from wear and contamination.

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.
