The Ohlins AP934 STX 46 Supersport rear shock is built to improve damping control and chassis stability on the Aprilia Tuono V4 Factory. It is aimed at consistent behaviour as loads rise under braking and acceleration, with clear feedback and repeatable setup changes. This unit uses a gas-separated layout to help maintain damping consistency during demanding use.

Ohlins | Made to race, perfected to ride

Developed from Ohlins racing experience, the STX Supersport range focuses on controlled support through corner entry, mid-corner and drive. The damping character is intended to keep the bike composed during high weight transfer without sacrificing the compliance needed for grip.

Who this shock is for

Suited to riders who want more precise rear-end control for sporty road riding and track days. If you are chasing a more supported feel under throttle and stronger stability during braking zones, this shock is designed to give you a wider, more useable tuning window than a comfort-focused setup.

Shock design & features

The STX 46 Supersport design uses a separated oil and gas arrangement to reduce aeration during repeated heavy inputs. Its internal damping circuits are designed to give distinct control over compression and rebound behaviour, supporting traction, stability and consistency as pace increases.

Tuning controls

• Compression damping: adjusts resistance to squatting and how supported the chassis feels during throttle application and rapid load changes.
• Rebound damping: controls return speed after compression, influencing rear tyre contact, grip recovery and how quickly the bike settles between corners.

Base setup (factory preset)

Supplied with a factory baseline intended for sporty road and track use, where higher cornering and braking loads demand firmer damping control. The emphasis is predictable behaviour and consistency, with scope to refine the feel for tyres, riding style and surface conditions.

Serviceability/lifecycle

Like any performance shock, periodic servicing helps maintain damping accuracy over time, especially with frequent hard riding or track work. Oil condition and seal wear directly affect feel and control, so inspection and scheduled refresh should be treated as normal maintenance.
