The Ohlins AP931 TTX RT is a rear shock unit for the Aprilia RSV4 1000, built to deliver consistent damping control and clear chassis feedback. It uses a gas-pressurised, oil/gas separated damping system to help maintain stability as temperatures and conditions change. This is a tunable package aimed at riders who want suspension response tailored to riding style and track conditions.

Ohlins | Made to race, perfected to ride

Ohlins rear shocks are developed around repeatable damping behaviour and a stable feel under load. The AP931 is intended to support predictable control through braking, turning, and acceleration, prioritising traction and clear feedback.

Shock design & features

This unit uses a gas-pressurised, oil/gas separated damping system to reduce fade and keep damping behaviour consistent during demanding use. It is a dedicated rear-fitment shock for the RSV4 1000, with internal valving focused on maintaining control as loads and speed increase.

Tuning controls

The AP931 provides independent damping adjustment for compression and rebound. Compression adjustment influences how the shock resists being driven into its stroke by bumps and load transfer, while rebound adjustment controls the return speed after compression, affecting stability, grip, and how the bike settles between corners.

Who this shock is for

This shock suits riders chasing sharper chassis control and more precise feedback, particularly for track-focused riding. It is best used when spring choice, sag, and overall geometry are matched to the rider and intended conditions.

Serviceability/lifecycle

As with any performance damper, routine servicing helps maintain internal condition and damping consistency over time. Inspection and oil refresh should be treated as normal maintenance, with frequency guided by use, heat exposure, and operating environment.

Before you install

Confirm fitment for your exact Aprilia RSV4 1000 variant and check all included hardware before installation. If this unit is being supplied as a replacement, note it has been replaced by AP360.
