The Ohlins AP933 STX 46 Supersport rear shock is a direct replacement unit for the Aprilia RSV4 1000 RR, developed for consistent rear-end control in demanding road and track use. It is built to support stable chassis behaviour and clearer feedback by helping maintain tyre contact through the stroke. The aim is repeatable damping response and tunability compared with a typical standard shock.

Ohlins | Made to race, perfected to ride

Ohlins Supersport shocks are engineered to deliver a predictable feel and a useful tuning range for track-focused riding while remaining practical on the road. They are designed to support the bike’s balance under braking, corner entry and drive without muting what the rear tyre is doing.

Who this shock is for

• Riders doing regular spirited road riding who want improved rear stability and feedback.
• Track day riders chasing more consistent damping behaviour during longer sessions.
• Owners replacing a worn rear mono shock and wanting a serviceable performance option.

Shock design & features

This is an oil/gas separated monotube design, using a pressurised gas chamber to help maintain damping consistency as loads and temperatures change. The STX 46 Supersport architecture is intended to provide controlled movement and predictable support across a wide range of riding conditions.

Tuning controls

• Rebound damping adjustment: helps manage how quickly the shock extends after compression, influencing grip, stability and drive on corner exit.
• Compression damping adjustment: tunes resistance to compression, influencing support under braking and mid-corner load as well as bump impact control.
• Spring preload adjustment: sets sag and ride height balance to suit rider load and intended use.

Base setup (factory preset)

The supplied factory settings are intended as a stable starting point for road and track use. Fine tuning is typically done around rider mass, tyres, geometry targets and the surfaces you ride on.

Serviceability/lifecycle

As a performance rear shock, periodic servicing helps maintain consistent damping and manage internal wear over time. Service intervals depend on usage and heat exposure, particularly with frequent track riding.
