The Ohlins KT2090 STX 46 MX is a rear mono shock absorber developed for KTM 85 SX motocross use. Built around Ohlins’ STX architecture, it’s designed to deliver consistent damping control and clear chassis feedback in demanding off-road conditions. Supplied without a spring, it is intended to be matched with the correct spring separately.

Ohlins | Made to race, perfected to ride

Ohlins off-road shocks are engineered with a focus on damping stability, traction management and predictable response. This unit is part of the STX 46 MX family, intended for motocross applications where repeatable performance matters.

Who this shock is for

  • KTM 85 SX riders wanting an Ohlins rear shock platform for motocross
  • Riders and tuners who want external damping adjustments to tailor feel and balance
  • Owners prepared to select and fit the appropriate spring (not supplied)

Shock design & features

This shock uses a pressurised, oil/gas separated design to support damping consistency under heat and repeated impacts. The STX 46 MX layout is intended to provide stable control through the stroke and maintain traction when conditions and loads change quickly.

Tuning controls

The KT2090 provides external rebound adjustment and compression adjustment across two circuits, allowing you to tune behaviour under both sharper hits and more general chassis movements. This makes it suitable for adapting to different tracks, grip levels and rider preferences without internal changes for every adjustment step.

Before you install

  • Spring is not supplied; refer to the specified spring series in the notes and select the correct rate for the rider and use
  • Confirm eye-to-eye length and fitment during installation and setup
  • Use the recommended Ohlins oil noted for service work

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.
