The Ohlins AP933 STX 46 Supersport rear shock is a replacement unit for the Aprilia RSV4 1000 RR, developed to deliver consistent rear-end control under demanding road and track use. It focuses on stable chassis behaviour and clear feedback by keeping tyre contact more controlled through the stroke. This is intended for riders who want more repeatable damping response than a typical standard shock.

Ohlins | Made to race, perfected to ride

Ohlins Supersport shocks are designed to provide a predictable feel and tuning range that suits track-focused riding while remaining usable on the road. The aim is to support the bike’s balance under braking, corner entry and drive without dulling what the rear tyre is communicating.

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 shock and wanting a serviceable performance option.

Shock design & features

This unit uses a gas-pressurised damping system to help maintain damping consistency as loads and temperatures change. The damping behaviour is managed through dedicated circuits, supporting more targeted tuning when you make adjustments.

Tuning controls

• Rebound damping: controls how quickly the shock extends after compression, influencing grip and stability on corner exit and over repeated bumps.
• Compression damping: controls resistance to compression, influencing support under braking and mid-corner load as well as impact response.

Base setup (factory preset)

The supplied baseline is intended as a stable, track-capable starting point with controlled movement and clear feedback. Final settings are typically refined to suit rider mass, tyres, ride height targets and the surfaces you ride on.

Serviceability/lifecycle

As a performance shock, periodic servicing helps maintain consistent damping and manage internal wear. How often it needs attention depends on usage, heat exposure and time on track, so it’s worth planning service work as part of regular maintenance.
