The Ohlins KA1490 STX 46 MX is a rear mono shock absorber developed for the Kawasaki KX 85. It’s built around Ohlins’ motocross damping architecture to provide consistent control through changing track conditions. Designed for riders who want a more tunable and composed feel from the rear of the bike without relying on generic settings.

Ohlins | Made to race, perfected to ride

Ohlins suspension components are engineered with a focus on damping control, stability and predictable feedback. The STX 46 MX family is intended for motocross and off-road use where repeatable performance and adjustability matter. This unit is configured as a dedicated rear shock for the KX 85 application.

Who this shock is for

  • Motocross riders chasing improved rear-wheel control and clearer chassis feedback.
  • Riders and tuners who want practical damping adjustability for different tracks and conditions.
  • Owners prepared to select the correct spring separately to suit rider weight and use.

Shock design & features

This shock uses a separated oil/gas layout with a remote reservoir to help maintain damping consistency under heat and repeated impacts. It’s a single rear mono configuration for modern MX linkages and swingarm loads. The architecture is intended to keep damping stable while allowing effective external tuning.

Tuning controls

External adjusters are provided for rebound damping and compression damping, including separate low-speed and high-speed compression control. This allows you to tune how the shock responds to chassis movements versus sharper hits, without changing internal valving. As with any performance shock, correct spring rate and sag settings are essential to make the damping adjustments meaningful.

Before you install

No spring is supplied with this shock. It requires a spring from the 00698- series (sold separately), so confirm the correct rate for the rider and intended use before installation. After fitting, set sag and baseline damping settings first, then fine-tune on track to match traction, support and comfort.

Serviceability/lifecycle

This is a rebuildable Ohlins unit intended to be serviced as part of normal motocross maintenance. Regular oil and seal servicing helps keep damping response consistent and protects internal components, particularly when the bike is used in dusty or muddy conditions.

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.
