The Ohlins STX 46 Supersport rear shock for the Ducati 999 Biposto is built to deliver stable damping control and clear chassis feedback for sporty road and track riding. Based on Ohlins racing development, it is intended to keep the rear tyre working consistently through braking, turn-in and acceleration. This unit uses a gas-pressurised design to help maintain damping consistency during demanding use.

Ohlins | Made to race, perfected to ride

Ohlins Supersport shocks are developed with a focus on predictable damping behaviour and repeatable setup changes. The STX platform is widely used for performance road and track applications where rider feel and stability matter.

Shock design & features

  • STX 46 Supersport architecture with gas-pressurised damping for consistent performance.
  • Mono rear shock configuration suited to the Ducati 999 Biposto rear suspension layout.
  • Built around independent damping circuits to support controlled weight transfer and traction management.

Tuning controls

This rear shock provides external adjustment for rebound damping and compression damping, allowing you to fine-tune the bike’s response for different tyres, surfaces and riding intensity. Preload is adjustable to set ride height balance and match the fitted spring to rider load.

Base setup (factory preset)

Ohlins supplies this unit with a factory baseline aimed at a well-rounded starting point for sporty riding. From there, damping and preload can be refined to suit rider preference, tyre choice and typical conditions.

Before you install

  • Confirm fitment for Ducati 999 Biposto and check clearance around the linkage and exhaust.
  • Set sag and preload first, then adjust rebound and compression in small steps to establish balance.
  • If you change tyres or ride conditions, revisit your settings to maintain stability and grip.

Serviceability/lifecycle

As with any high-performance shock, regular servicing helps maintain damping consistency and component life. Service intervals depend on use, especially if the bike sees frequent track days.
