The Ohlins KT1990 STX 46 MX is a rear mono shock absorber developed for the KTM 85 SX. It is built around Ohlins’ STX architecture to provide controlled damping and consistent feel across changing track conditions. Supplied without a spring, it is intended to be matched with an appropriate spring as noted for this application.

Ohlins | Made to race, perfected to ride

Who this shock is for

  • KTM 85 SX riders wanting a dedicated Ohlins rear shock upgrade
  • Riders and tuners who want external adjusters to tailor the bike to track conditions
  • Owners prepared to select and fit a suitable spring (no spring supplied)

Shock design & features

This is an oil/gas separated shock design (not an emulsion type), intended to maintain damping consistency as temperatures and workload change. The configuration is suited to PDS fitment as noted for this model.

Tuning controls

  • Rebound damping adjustment
  • Compression damping adjustment with separate low-speed and high-speed circuits

Before you install

  • No spring is supplied; select the correct spring for the specified 00698-series requirement
  • Confirm fitment for KTM 85 SX rear mono / PDS application before installation
  • Use the recommended Ohlins shock oil as specified for this unit

Serviceability/lifecycle

This Ohlins unit is designed to be serviced and re-valved to suit rider preference and conditions. Regular inspection and periodic servicing will help maintain performance and component life.

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.
