The Ohlins AP751 STX 46 Supersport rear shock absorber is designed for the Aprilia RS 125, focusing on controlled, predictable damping and clear rear-tyre feedback. It uses an oil/gas separated layout to help maintain damping consistency through repeated use. The adjusters are intended to make changes measurable, so you can tune balance and grip without masking issues elsewhere in the chassis.

Ohlins | Made to race, perfected to ride

Ohlins Supersport units are developed around stable damping behaviour and direct feel. The intent is a rear end that stays composed through braking, turn-in and acceleration, with adjustments that respond clearly when you change settings.

Shock design & features

This is an oil/gas separated rear mono shock built on Ohlins STX 46 Supersport architecture. Keeping the gas separated from the oil helps reduce aeration and supports more consistent damping behaviour as temperatures and loads change.

Tuning controls

  • Rebound damping: Controls how quickly the shock extends after a bump or on corner exit, influencing stability and drive.
  • Compression damping: Controls how the shock resists movement under load, influencing support under braking, initial throttle application and mid-corner balance.
  • Length adjustment: Allows rear ride-height changes to refine chassis attitude and steering response.

Base setup (factory preset)

The supplied baseline settings are intended as a starting point for typical sporty road and track use on an RS 125. From there, tuning is best done in small steps so it’s clear whether the bike needs more support, more compliance, or a different front-to-rear balance.

Serviceability/lifecycle

As a serviceable Ohlins unit, long-term performance depends on oil condition and seal health. Periodic servicing helps maintain consistent damping and ensures the adjusters continue to produce meaningful, repeatable changes.

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.
