The Ohlins AP840 STX 46 Supersport rear shock is designed to improve damping control on the Aprilia RSV 1000 Mille chassis. Based on Ohlins race-derived architecture, it aims to maintain tyre contact and deliver predictable response as loads change under braking, turn-in and acceleration. This unit uses a gas-pressurised damping system to support consistency during harder use.

Ohlins | Made to race, perfected to ride

Built for riders who want clearer rear-end feedback and more repeatable control than standard equipment. The focus is on stability without muting what the rear tyre is doing, so grip changes are easier to read and manage.

Who this shock is for

Suited to performance road riding and track days where the RSV 1000 Mille benefits from more controlled damping behaviour. It’s a sensible choice if you’re chasing improved composure through transitions and better support when driving out of corners.

Shock design & features

The AP840 is an Ohlins STX 46 Supersport rear shock using a gas-pressurised damping layout with oil and gas separated (not emulsion). Keeping the damping circuit pressurised helps reduce fade and cavitation under sustained load, supporting more consistent behaviour over longer sessions.

Tuning controls

• Compression damping: tunes how the rear resists squat and absorbs bumps under load, influencing support on corner entry and drive.
• Rebound damping: controls return speed after compression, influencing stability between bumps and how quickly the bike settles after transitions.

Base setup (factory preset)

Ohlins Supersport baseline valving is intended as a practical starting point for performance road and track use, with adjustment range to match rider mass, tyres and conditions. Final balance comes from pairing damping settings with correct spring preload and sag.

Serviceability/lifecycle

Periodic servicing helps maintain damping consistency and seal condition, particularly if the bike sees regular track use. Keeping the unit clean around the shaft area and addressing any leaks or performance drop-offs early helps reduce wear and preserve feel.
