The Ohlins AP340 TTX GP rear shock is a dedicated rear suspension unit for the Aprilia RSV4 1000, built around Ohlins’ race-developed damping architecture. It is designed to deliver consistent damping behaviour under high load with clear feedback for chassis balance tuning. This unit uses a separated oil and gas design to help maintain stability during sustained, demanding use.

Ohlins | Made to race, perfected to ride

TTX GP shocks are developed to provide predictable support and a strong connection to rear grip as pace and conditions change. The focus is repeatable damping control so setup changes translate cleanly on track.

Shock design & features

This is a TTX GP rear mono shock using a twin-tube style damping layout with separated oil and gas. The design is aimed at stable damping performance and consistent feel through temperature and load variation.

Tuning controls

This shock provides external adjustment for rebound damping and compression damping, plus spring preload. Rebound adjustment influences how the rear returns after bumps and load transfer, affecting stability and drive grip. Compression adjustment influences support under acceleration and when the rear is loaded through corners, shaping chassis attitude and how firmly the bike rides into the stroke. Preload is used to set sag and establish baseline balance before refining damping.

Base setup (factory preset)

The baseline valving is intended for supersport track use on the RSV4 platform, where clear responses to setup changes are important. Fine tuning can then be made to suit tyre choice, track grip, and rider preference.

Serviceability/lifecycle

As a rebuildable Ohlins unit, periodic servicing is part of maintaining performance and consistency. Service intervals depend on use intensity; track use typically shortens the time between oil and seal maintenance.

Before you install

Confirm fitment for the Aprilia RSV4 1000 and plan your setup sequence before the first ride. Start by setting sag and chassis balance with preload, then use rebound and compression adjustments in small steps to refine grip, support, and stability.
