The Ohlins AP351 STX 46 Supersport rear shock is a direct replacement unit for the rear mono-shock position on selected Aprilia models. Built on the STX 46 Supersport platform, it is designed to provide controlled, consistent damping and a practical tuning range for mixed road and track use. The shock uses a gas-separated design to help maintain damping stability as temperatures and loads change.

Ohlins | Made to race, perfected to ride

Developed from Ohlins’ track-focused shock architecture, this unit prioritises clear feedback and repeatable chassis behaviour. It is intended for riders who want a serviceable, motorsport-style rear shock with meaningful adjustment for setup work.

Shock design & features

This is a gas-pressurised, oil/gas separated rear shock (not an emulsion design). The separated layout helps reduce cavitation risk and supports more consistent damping during longer sessions.

Tuning controls

  • Rebound damping: controls how quickly the shock extends after bumps and acceleration loads, influencing stability and traction.
  • Compression damping: controls resistance to compression under braking, bumps and cornering loads, influencing support and ride harshness.

Is it right for you?

Suitable where a rear mono shock is required for the listed Aprilia RSV 1000 R Factory and Tuono fitments. As with any tuning component, results depend on overall chassis condition and a sound baseline setup.

Serviceability/lifecycle

This is a serviceable Ohlins unit, and periodic maintenance helps keep damping consistent and protects internal components. Service needs vary with use and exposure, with harder track use typically requiring more frequent attention.
