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
