The Ohlins KA1790 is an STX 46 MX rear mono shock absorber for Kawasaki KX 85 applications. Built around Ohlins motocross damping know-how, it’s intended to deliver controlled, consistent suspension behaviour in demanding conditions. This unit is supplied without a spring, with fitment notes specifying the appropriate Ohlins spring series.

Ohlins | Made to race, perfected to ride

STX 46 MX shocks are designed for off-road racing where traction, stability and repeatable damping matter. The KA1790 sits in Ohlins’ MX & Enduro shock range and follows their serviceable, tune-focused approach.

Shock design & features

This shock uses an oil/gas separated layout to help maintain damping consistency during hard use. The STX architecture is designed to provide controlled movement through the stroke and predictable chassis response.

Tuning controls

The KA1790 provides rebound damping adjustment along with compression damping adjustment in two circuits, allowing you to tailor response to track conditions and rider preference. These external adjusters support baseline setup changes without internal revalving.

Base setup (factory preset)

Ohlins supply these units with a factory baseline intended as a starting point before setting sag and balance for the bike and rider. Final setup will depend on spring choice, track surface and pace.

Before you install

No spring is supplied with this shock. The notes indicate a 00698-series spring is required and is sold separately, so confirm spring selection before installation.

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.
