The Ohlins KA238 STX 46 Street rear shock is built for Kawasaki GPZ 750 applications where controlled damping and consistent chassis behaviour matter. It uses a gas-pressurised damping system to help maintain performance during sustained road use. Designed as a rear mono shock, it supports confident traction and stability with a tuneable setup.

Ohlins | Made to race, perfected to ride

STX 46 Street products are developed from Ohlins suspension know-how to deliver predictable handling and clear feedback. The KA238 focuses on practical adjustability and durability for street-focused riders who still value accurate control.

Who this shock is for

  • Riders refreshing ageing rear suspension to regain stability and grip
  • Owners who want a quality baseline with adjustment to suit load and conditions
  • GPZ 750 riders seeking more consistent damping feel in real-world riding

Shock design & features

  • Gas-pressurised damping system to support consistent performance
  • Rear mono-shock configuration for the specified fitment
  • Ohlins STX 46 Street architecture intended for controlled response and chassis stability

Tuning controls

  • Rebound damping adjustment

Base setup (factory preset)

This shock is supplied with an Ohlins fitted spring (yellow) and an Ohlins-defined base setting as a starting point. Fine-tuning rebound damping and spring preload is typically used to suit rider weight, load and riding conditions.

Before you install

  • Confirm correct fitment for your Kawasaki GPZ 750 and linkage/mount condition before installation
  • After installation, check sag and re-check fasteners after an initial shakedown ride

Serviceability/lifecycle

Ohlins shocks are designed to be serviced to maintain performance over time. Using the recommended Ohlins oil during servicing helps keep damping response consistent.

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.
