The Ohlins AP360 is a rear TTX GP shock absorber designed for Aprilia RSV4 1000 and RSV4 1000 RR applications. Built around Ohlins’ track-oriented damping architecture, it focuses on consistent control and clear tyre feedback under demanding use. It is intended for riders who want a broad, usable adjustment range to balance grip, support and stability.

Ohlins | Made to race, perfected to ride

TTX GP units are developed from Ohlins racing programs and tuned for performance road and track riding. The intent is predictable chassis behaviour through corners, braking zones and acceleration transitions, with damping control that remains consistent over extended sessions.

Design architecture

This shock uses a twin-tube TTX-style damping layout with oil and gas separated for stable performance and reduced aeration compared with emulsion designs. The layout supports consistent damping behaviour as temperatures and workloads rise, which is a key requirement for track-focused setups.

Adjustments & what they change

• Rebound damping: influences how quickly the rear returns after bumps and load changes, affecting stability on corner exit and over crests.
• Compression damping: influences how the rear resists squat and absorbs bumps under acceleration and mid-corner load, affecting support and grip.
• Ride height adjustment: allows geometry changes to refine turn-in, mid-corner balance and drive without relying solely on preload changes.

Factory baseline intent

The baseline valving and spring fitment are aimed at a track-biased balance for the RSV4 platform, providing support under high load while retaining usable compliance. Fine-tuning is typically used to match tyre choice, rider mass, and the amount of track versus road use.

Serviceability & lifecycle

As a high-performance rear shock, periodic servicing is part of keeping damping response consistent. Regular oil and seal maintenance helps preserve adjuster effectiveness and ensures the shock continues to deliver repeatable feel across sessions.

Setup considerations

Start by confirming sag and ride height targets, then use rebound to manage stability and recovery, and compression to manage support and bump absorption. Small, systematic changes make it easier to identify whether a handling issue is caused by geometry, spring balance or damping.
