The Ohlins KT2190 STX 46 MX rear shock is built for motocross use on the KTM 85 SX, focusing on controlled damping and consistent feel. It uses a gas-pressurised design to help maintain performance through changing track conditions. With separate adjustment circuits, it’s suited to riders who want a suspension unit that can be tuned to match pace, grip and rider preference.

Ohlins | Made to race, perfected to ride

Developed from Ohlins’ motocross program, the STX 46 MX platform is aimed at providing predictable chassis behaviour under braking, acceleration and corner load. The intent is stable handling with clear feedback, so changes to setup are easier to feel and validate.

Shock design & features

  • Rear mono shock for KTM 85 SX fitment
  • Gas-pressurised, oil/gas separated architecture to support consistent damping
  • Independent damping circuits to separate key adjustments

Tuning controls

  • Rebound damping adjustment
  • Compression damping adjustment
  • Additional compression adjustment range for finer control across track conditions

Before you install

  • No spring is supplied; the spring is sold separately (see notes in the product information)
  • Confirm spring selection and sag targets with your rider weight and typical track surface in mind
  • Use the recommended Ohlins shock oil as listed for this unit

Serviceability/lifecycle

This is a fully serviceable Ohlins competition shock designed for routine maintenance. Regular oil and seal service helps keep damping consistent and protects internal components when used in dusty, high-load motocross conditions.

Is it right for you?

If you’re looking for an Ohlins rear shock for KTM 85 SX with gas-pressurised consistency and external compression and rebound adjustability, this unit matches that brief. It’s a good fit when you want more control over feel and balance rather than a set-and-forget replacement.

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.
