The Ohlins DU139 STX 46 Supersport rear shock is a bolt-on rear mono shock for the Ducati 999. It’s built around Ohlins’ track-focused damping architecture to deliver clear chassis feedback and consistent control under demanding riding. Designed as a gas-pressurised unit, it maintains stable damping behaviour through heat and repeated load changes.

Ohlins | Made to race, perfected to ride

Ohlins Supersport shocks are developed with a racing baseline, then refined for real-world trackday and fast-road use. The DU139 is intended to improve rear-end support, grip and stability while keeping the ride tuneable.

Shock design & features

  • STX 46 Supersport rear mono shock format for Ducati 999 fitment
  • Gas-pressurised, oil/gas separated design to help keep damping consistent during extended use
  • Ohlins valving strategy aimed at predictable traction and chassis control

Tuning controls

This shock includes external damping adjustments for rebound and compression, allowing you to tailor support and grip to tyres, pace and surface conditions. Spring preload adjustment is also provided for setting ride height and sag correctly.

Base setup (factory preset)

The DU139 is supplied with an Ohlins baseline setting intended to work as a starting point for the Ducati 999. From there, fine adjustments can be made to match your weight, tyres and intended use.

Before you install

  • Confirm the motorcycle model and year compatibility for Ducati 999 applications before fitting.
  • Set sag and preload before making damping changes, then adjust rebound and compression methodically.
  • If your current linkage or bearings are worn, address these first to get the best result from the shock.

Serviceability/lifecycle

As with other Ohlins performance units, periodic servicing helps maintain damping consistency and component life. Regular inspection is recommended if the bike sees track use or high heat cycles.

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.
