The Ohlins AP750 STX 46 Supersport rear shock for the Aprilia RS 125 is designed to improve rear-end control and consistency under performance riding. It uses a gas-pressurised, oil/gas separated layout to help maintain stable damping behaviour as temperatures and loads change. The focus is on clear chassis feedback and repeatable setup changes.

Ohlins | Made to race, perfected to ride

Built within the STX 46 Supersport family, this unit follows Ohlins’ racing-derived approach to damping control, aiming for predictable feel at higher pace. It is intended for riders who want a serviceable shock with practical external adjustments for circuit work and focused road use.

Shock design & features

This is a monotube STX-style rear shock with oil/gas separation and gas pressurisation to reduce cavitation and support consistent damping response. It is supplied as a rear mono replacement for the Aprilia RS 125 application.

Tuning controls

The shock includes rebound damping adjustment to manage how quickly the rear extends after bumps and weight transfer, influencing stability and traction on corner exit. Compression damping adjustment is provided to tune support under load and acceleration, affecting squat and chassis attitude. Ride height adjustment is also included, allowing geometry changes to fine-tune turn-in and balance.

Base setup (factory preset)

The factory baseline is set with a Supersport intent, providing a structured starting point for further refinement. Use the adjusters to adapt to rider preference, tyres and conditions rather than to compensate for incorrect springing or chassis balance.

Before you install

If you change ride height, do it methodically and re-check overall chassis balance, as geometry changes can alter steering response and stability. After installation, verify sag and then adjust compression and rebound in small steps, assessing one change at a time for clear cause and effect.

Serviceability/lifecycle

This Ohlins unit is designed to be serviceable, supporting routine oil and seal maintenance to keep damping consistent over time. Regular servicing is particularly important when used in higher-heat or track conditions.

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.
