The Ohlins AP468 TTX GP rear shock is built around a twin-tube damping concept developed for consistent control under demanding track and fast-road use. It is a mono rear unit intended to deliver clear chassis feedback and stable support as loads change through braking, turning and drive. This model is specified for the Aprilia RSV4 application set listed in the product name.

Ohlins | Made to race, perfected to ride

TTX GP units focus on repeatable damping behaviour and clean separation of damping functions to help the tyre stay in contact with the road. The aim is to provide predictable support and traction without relying on an overly stiff ride to create stability.

Design architecture

This shock uses a gas-pressurised, oil/gas separated design rather than an emulsion layout. The twin-tube arrangement is intended to keep damping performance consistent as operating conditions and piston speeds vary, supporting confidence during longer sessions.

Adjustments & what they change

• Rebound damping to control how quickly the rear returns after being compressed, influencing stability on corner exit and over successive bumps.
• Compression damping to manage how the shock resists bump and load input, affecting support under acceleration and when loading the rear through geometry changes.
• Ride height adjustment to fine-tune chassis attitude and steering response without using spring preload as a geometry tool.
• Spring preload to set static and rider sag so the damping adjustments work in their intended range.

Factory baseline intent

The supplied baseline is typically set to suit the target motorcycle and a broad spread of rider weights and pace, with scope to refine for tyre choice and track surface. For best results, establish sag first, then adjust damping to address specific symptoms such as squat on drive or harshness over edge bumps.

Serviceability & lifecycle

This is a fully serviceable rear shock. Regular servicing helps maintain oil condition, gas pressure and seal performance, keeping damping behaviour consistent over time and ensuring adjuster response remains accurate.
