The Ohlins AP468 TTX GP rear shock is a dedicated rear mono unit for the Aprilia RSV4 applications listed. It uses a twin-tube damping concept developed to maintain consistent control as loads change through braking, cornering and acceleration. The focus is on clear chassis feedback and stable support for track and fast-road use.

Ohlins | Made to race, perfected to ride

TTX GP shocks are designed around repeatable damping behaviour and a clean separation of damping functions. The aim is predictable support and traction, with adjustability that lets you tailor feel without relying on excessive stiffness.

Shock design & features

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

Tuning controls

  • Rebound damping to manage how quickly the shock extends after compression, influencing stability and grip as the rear recovers between bumps and on corner exit.
  • Compression damping to control resistance to bump and load input, affecting support under acceleration and when the rear is being loaded through geometry changes.
  • Ride height adjustment to fine-tune chassis attitude and steering response without using preload as a geometry tool.
  • Spring preload to set sag so the damping adjustments operate in their intended range.

Base setup (factory preset)

The supplied baseline is set up to suit the target motorcycle and a broad spread of rider weights and pace, leaving scope to refine for tyres and surface conditions. Establish sag first, then adjust compression and rebound to address specific symptoms such as squat on drive or harshness over sharper bumps.

Serviceability/lifecycle

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