The Ohlins KA401 STX 46 Supersport rear shock is built to provide controlled, consistent damping on the Kawasaki ZX-4RR and ZX4-R. Based on Ohlins circuit development, it is intended for riders who want clear chassis feedback and a stable platform under hard acceleration, braking and fast direction changes. This unit uses a gas-pressurised, oil/gas separated design to help maintain damping consistency during sustained hard use.

Ohlins | Made to race, perfected to ride

Developed from Ohlins racing know-how, the STX 46 Supersport platform focuses on repeatable damping behaviour and predictable tyre contact. It is designed to be tuned to suit your pace, tyres and track conditions without losing ride feel.

Who this shock is for

  • Track riders and racers chasing stronger rear-end control and clearer grip feedback
  • Riders who want a dedicated performance shock with external damping adjustments
  • Owners looking to refine chassis balance and corner-exit drive on the ZX-4RR/ZX4-R

  • Gas-pressurised design with oil/gas separation to support stable damping under load

Before you install

  • Confirm correct fitment for your exact model/variant and intended use

Serviceability/lifecycle

This Ohlins unit is designed to be serviced and revalved, supporting long-term performance through periodic maintenance. Regular servicing helps keep damping consistency and protect internal components from oil degradation and wear.

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.
