The Ohlins KT1790 STX 46 MX is a rear mono shock for the KTM 85 SX, developed from Ohlins motocross racing experience. It’s built to deliver consistent damping feel and clear chassis feedback through changing track conditions. This unit uses a gas-pressurised, oil/gas separated design to help maintain stability during repeated hard hits.

Ohlins | Made to race, perfected to ride

STX motocross shocks are engineered to keep the rear of the bike composed under acceleration, braking and corner entry. The focus is on control and consistency so you can tune the bike around your riding style and track layout.

Who this shock is for

Suited to KTM 85 SX riders chasing a more controlled rear end feel for motocross use. It’s a good fit when you want more tuning range than stock and a shock designed to handle the repeated load cycles of MX riding.

Shock design & features

  • Gas-pressurised damping with oil/gas separation to support consistent performance under heat and sustained use
  • STX motocross architecture aimed at improving traction and stability through rough sections
  • Rear mono shock configuration for the KTM 85 SX

Tuning controls

This shock provides external damping adjustments for compression and rebound, allowing you to fine-tune response for track conditions, grip level and rider preference.

Before you install

  • No spring is supplied; the correct spring is sold separately (refer to the noted spring series)
  • Use the recommended Ohlins oil as specified for the unit

Serviceability/lifecycle

As a rebuildable Ohlins motocross shock, it’s intended to be serviced to maintain performance over time. Regular servicing helps keep damping consistent and protects internal components from wear.

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.
