The Ohlins AP822 STX 46 Supersport rear shock is designed to deliver consistent damping control and clear feedback for the Aprilia RSV mille SP. Built around a pressurised gas layout, it aims to maintain damping stability as operating temperatures change. The included adjusters allow practical chassis tuning for grip, support and balance.

Ohlins | Made to race, perfected to ride

Developed from Ohlins racing experience, the STX 46 Supersport platform focuses on predictable behaviour and repeatable setup changes. The goal is a stable, communicative rear end under braking, mid-corner load and acceleration.

Who this shock is for

This unit suits riders looking for more controlled rear suspension behaviour on road or track, and who want the ability to tune feel and support as tyres, pace and conditions change. It is a fit-for-application replacement shock for the RSV mille SP rear mono position.

Shock design & features

This is an oil and gas separated shock with a gas-pressurised damping system to reduce aeration and help resist damping fade. The STX 46 architecture is intended to keep damping response stable and consistent across longer sessions.

Tuning controls

• Rebound damping: adjusts how quickly the shock extends after bumps and after acceleration squat, influencing stability and traction on corner exit.
• Compression damping: adjusts resistance to load transfer under braking and cornering, affecting support and compliance.
• Spring preload: adjusts initial spring tension and ride height balance, influencing chassis attitude and how the bike uses available travel.

Base setup (factory preset)

The supplied baseline tune is intended as a practical starting point for the Aprilia RSV mille SP with the fitted spring. From there, refine preload and damping to match rider weight, tyre choice and typical surface conditions.

Serviceability/lifecycle

Like all performance dampers, ongoing consistency depends on periodic servicing to refresh oil and seals and inspect wear items. Regular maintenance helps preserve damping accuracy, particularly when the bike is used hard.
