The Ohlins AP466 TTX GP rear shock is built for riders chasing controlled chassis behaviour and clear feedback on an Aprilia RSV4 1000 or RSV4 1000 RR. It uses a gas-pressurised design to keep damping consistent as conditions and temperatures change. This unit is intended for precise tuning rather than broad “one setting fits all” performance.

Ohlins | Made to race, perfected to ride

TTX GP sits in Ohlins’ race-focused shock family, aimed at delivering repeatable damping and predictable grip feel when the bike is being ridden hard. The focus is stability under load changes and maintaining support through corner entry, mid-corner and drive.

Design architecture

This is a gas-pressurised shock with oil and gas separated rather than an emulsion layout. The TTX architecture is designed to manage damping in a controlled, consistent way, helping reduce fade and keeping response stable over longer sessions.

Adjustments & what they change

• Rebound damping: controls how quickly the rear extends after being compressed, influencing stability and grip on corner exit and over successive bumps.
• Compression damping: manages how the rear resists being compressed under braking, kerb strikes and acceleration load, affecting support and how firmly the bike holds its line.
• Ride height: allows chassis attitude changes without relying solely on spring preload, influencing steering speed, stability and drive characteristics.

Factory baseline intent

The baseline set-up is aimed at providing a workable starting point for the RSV4 platform while leaving enough adjustment range for tyre choice, pace, and track surface. Fine-tuning is typically done to balance rear support with traction and to match the front-end behaviour.

Setup considerations

Start by confirming spring and preload are appropriate for rider weight and use, then use damping to control movement rather than to mask an incorrect spring choice. Make one change at a time and keep notes, as compression and rebound changes can interact with ride height and overall chassis balance.

Serviceability / lifecycle

This Ohlins unit is designed to be serviced and reconditioned. Regular oil and seal maintenance helps preserve damping consistency and protects internal components, particularly when used in track conditions.
