The Ohlins AP931 TTX RT is a rear shock unit for the Aprilia RSV4 1000, built to deliver consistent damping control and clear chassis feedback. It uses a gas-pressurised, oil/gas separated damping system to help maintain stability as temperatures and conditions change. This is a tunable package aimed at riders who want suspension response tailored to riding style and track conditions.

Ohlins | Made to race, perfected to ride

Ohlins rear shocks are developed around repeatable damping behaviour and a stable feel under load. The AP931 is intended to support predictable control through braking, turning, and acceleration, prioritising traction and clear feedback.

Shock design & features

This unit uses a gas-pressurised, oil/gas separated damping system to reduce fade and keep damping behaviour consistent during demanding use. It is a dedicated rear-fitment shock for the RSV4 1000, with internal valving focused on maintaining control as loads and speed increase.

Tuning controls

The AP931 provides independent damping adjustment for compression and rebound. Compression adjustment influences how the shock resists being driven into its stroke by bumps and load transfer, while rebound adjustment controls the return speed after compression, affecting stability, grip, and how the bike settles between corners.

Who this shock is for

This shock suits riders chasing sharper chassis control and more precise feedback, particularly for track-focused riding. It is best used when spring choice, sag, and overall geometry are matched to the rider and intended conditions.

Serviceability/lifecycle

As with any performance damper, routine servicing helps maintain internal condition and damping consistency over time. Inspection and oil refresh should be treated as normal maintenance, with frequency guided by use, heat exposure, and operating environment.

Before you install

Confirm fitment for your exact Aprilia RSV4 1000 variant and check all included hardware before installation. If this unit is being supplied as a replacement, note it has been replaced by AP360.

Öhlins Motorcycle Suspension Warranty

New Öhlins motorcycle shock absorbers, front forks and cartridge kits supplied by Teknik Motorsport are covered by the applicable Öhlins manufacturer’s warranty against defects in materials and workmanship.

Teknik Motorsport is an authorised Öhlins Service Centre and administers warranty claims in accordance with the Öhlins warranty conditions. The service intervals below form part of the maintenance requirements for Öhlins products supplied and supported by Teknik Motorsport.

This warranty is in addition to the consumer guarantees that apply under the Australian Consumer Law.

  • Registered motorcycles — non-competition road use Five years, subject to correct application, installation, setup and servicing every: 20,000 km or two years, whichever occurs first.
  • Registered motorcycles — adventure and light off-road use Five years, subject to correct application, spring rate, setup and servicing every: 10,000 km or annually, whichever occurs first.
  • Unregistered or competition motorcycles Two years for eligible Öhlins MX and Enduro products, subject to inspection every ten hours and servicing every: 30 operating hours or annually, whichever occurs first.

Compliance with the applicable service interval is a condition of the Öhlins manufacturer’s warranty. Evidence of servicing may be required when a warranty claim is assessed.

A seal leak, loss of damping performance or internal wear arising after the prescribed service interval has been exceeded will be treated as a service or maintenance issue rather than a manufacturing defect.

Warranty repairs

Öhlins suspension products are designed to be serviced and repaired. Where a warranty claim is approved, the normal remedy is repair of the customer’s original suspension unit using genuine Öhlins replacement parts.

Replacement of a complete shock absorber, fork or cartridge kit is not automatic and would normally occur only where the product has suffered a manufacturing failure that cannot reasonably be repaired. This is at Ohlins discretion. 

Öhlins spare parts and service kits

Öhlins spare parts, seals, bushes, service kits, springs, fluids and individual components are covered only against defects present when supplied.

No fixed age-based warranty applies to wear items, service parts or consumable components. Wear, deterioration, contamination, incorrect installation and damage caused by another component are not manufacturing defects.

Öhlins gives the customer a meaningful five-year warranty on products (Units), provided the suspension is maintained as suspension should be maintained. Teknik supports that warranty locally, can inspect the product properly, and can repair it with genuine parts rather than discarding it.
