The Ohlins KA721 STX 46 Supersport rear shock is built for Kawasaki ZX-7R riders who want more control and clearer feedback from the rear tyre. Developed from race-derived suspension practice, it focuses on stability under load and consistent damping over a session. This unit uses a gas-pressurised damping system to help reduce fade and maintain repeatable behaviour.

Ohlins | Made to race, perfected to ride

Ohlins Supersport shocks are designed to deliver precise chassis control and predictable grip, especially when braking hard and driving out of corners. The KA721 is a dedicated fitment for the ZX-7R, intended as a direct-performance upgrade to the stock rear suspension.

Who this shock is for

Suited to riders who do track days, spirited road riding, or are chasing more consistent handling as pace increases. It is also a practical choice if you want a broader tuning window than an OE shock can provide.

Shock design & features

  • STX 46 Supersport architecture
  • Gas-pressurised damping system for consistent performance
  • High-speed response characteristics aimed at improving chassis control
  • Valving developed with race use in mind to support traction and stability

Tuning controls

This shock provides external damping adjustment for both compression and rebound, allowing you to tune support under load and manage how quickly the rear returns after bumps, braking, and corner exit drive.

Before you install

Set static and rider sag, then confirm linkage condition and bearings before fitting. After installation, start by evaluating rebound control and drive grip, then refine compression to balance support and compliance.

Serviceability/lifecycle

Like all high-performance shocks, periodic servicing helps keep damping consistent and protects internal wear parts. Regular inspection and oil/gas refresh are recommended as use and operating conditions accumulate.

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.
