The Ohlins BM633 STX 46 Adventure rear shock is a replacement rear mono shock for the BMW G 650 Xmoto, built around Ohlins’ STX architecture for consistent damping control in mixed-surface use. It is designed to improve chassis stability and comfort when conditions change, from sealed roads to rougher tracks. Adjustment is provided externally so you can tune feel without disassembly.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a focus on damping control, heat management and repeatable performance. The STX 46 Adventure family is intended for real-world adventure and touring duty where traction, support and comfort all matter.

Shock design & features

This is an oil/gas separated monotube design rather than an emulsion shock, helping maintain damping consistency over longer, rougher rides. As a rear mono shock, it is built to support the bike’s weight transfer under braking and acceleration while keeping the rear tyre working across variable surfaces.

Tuning controls

The BM633 includes rebound damping adjustment, compression damping adjustment, and spring preload adjustment. These controls let you balance comfort and support, and fine-tune response for different roads, loads and riding pace.

Base setup (factory preset)

It is supplied with a factory baseline setting intended to suit the standard application. Use that as your starting point, then adjust one change at a time to achieve the feel you want for your weight, luggage and typical terrain.

Before you install

Confirm correct fitment for the BMW G 650 Xmoto and inspect mounting hardware and linkage condition before installation. After fitting, set sag via preload and then refine rebound and compression to match your riding conditions.

Serviceability/lifecycle

As an Ohlins unit, the shock is designed to be serviceable. Periodic servicing helps maintain damping performance and reliability, particularly if the bike is used regularly on rough surfaces.

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.
