The Ohlins KA2190 STX 46 MX is a rear mono shock absorber developed for Kawasaki KX 85 motocross applications. Built around Ohlins’ STX architecture, it’s designed to deliver consistent damping response and clear chassis feedback across changing track conditions. This unit is supplied without a spring, allowing the correct rate to be selected for rider weight and use.

Ohlins | Made to race, perfected to ride

STX 46 MX shocks are engineered for riders who want dependable control and tuneability from a purpose-built motocross damper. The design focuses on stability through braking bumps, support in corners, and traction on acceleration, with damping behaviour intended to remain consistent as conditions vary.

Who this shock is for

  • Kawasaki KX 85 riders replacing a worn or underperforming rear shock
  • Motocross riders who want a higher level of damping control and adjustability
  • Owners who prefer selecting a spring rate separately to suit rider weight and track conditions

Shock design & features

This is an oil/gas separated, gas-pressurised shock design intended to reduce fade and maintain predictable damping during repeated heavy impacts. The STX layout separates damping functions for more controlled response and improved feel at the rear wheel.

Tuning controls

The KA2190 provides external adjusters for rebound damping and compression damping. This allows changes to how quickly the shock extends after an impact and how it resists compression under bumps, landings, and load transfer.

Before you install

  • No spring is supplied; confirm the correct spring for your application before installation
  • Check linkage, swingarm bearings, and mounting hardware condition to get the full benefit of the shock
  • Plan a baseline setup after fitment and record changes as you tune

Serviceability/lifecycle

As a serviceable Ohlins motocross shock, performance is best maintained with regular inspection and periodic servicing based on use and riding conditions. Fresh oil, seals, and correct gas pressure help keep damping consistent over time.

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.
