The Ohlins AP660 STX 46 Supersport rear shock is built for controlled damping and consistent feel in demanding road and track use on the Aprilia RS 660 and Tuono 660. It uses a pressurised oil/gas separated design to help maintain damping stability as temperatures and loads change. This unit is intended for the rear mono-shock position.

Ohlins | Made to race, perfected to ride

Ohlins suspension units focus on predictable damping behaviour and clear adjustment response. The STX 46 Supersport family is designed around usable chassis control and maintaining tyre contact through a broad, practical tuning range.

Shock design & features

This is a mono-shock with a pressurised, oil/gas separated damping system rather than an emulsion layout. Separating oil and gas helps reduce aeration under sustained use and supports repeatable damping performance.

Tuning controls

  • Rebound damping: controls how quickly the shock extends after being compressed, influencing stability and grip as the bike transitions off the brake and onto throttle.
  • Compression damping: controls resistance to shock movement under load, influencing support during braking and load transfer, plus bump absorption.
  • Spring preload: sets the operating point in the stroke and rear ride balance, influencing traction, turning behaviour and comfort.

Base setup (factory preset)

The supplied baseline valving and spring fitment are intended as a workable starting point for typical RS 660 / Tuono 660 use across a range of rider weights. Final performance depends on correct sag and aligning damping settings to tyres, pace and surface.

Before you install

Confirm rear sag and overall front-to-rear balance before making damping changes. Make one adjustment at a time and evaluate on the same section of road or within the same track session so cause and effect remain clear. If the bike feels harsh over sharp bumps, review compression first; if it feels unsettled after bumps or on corner exit, review rebound.

Serviceability/lifecycle

This Ohlins unit is designed to be maintained with periodic oil and seal service to keep damping consistent. Service needs vary with use intensity, heat exposure and contamination, and will generally be more frequent with regular track use.

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.
