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.

  • 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

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?
