The Ohlins STX 46 Supersport rear shock for KTM RC 390 is built for riders chasing clear feedback and predictable chassis behaviour under load. Developed from Ohlins race-bred damping concepts, it focuses on stability, traction and consistency when riding hard. This is a gas-pressurised, oil/gas separated shock architecture intended for performance road and track use.

Ohlins | Made to race, perfected to ride

STX Supersport units are designed to deliver controlled damping with strong support through braking, turn-in and acceleration. The goal is repeatable performance and a planted rear tyre feel when conditions and pace change.

Who this shock is for

  • KTM RC 390 riders wanting improved rear-end stability for track days and spirited road riding
  • Riders looking for more precise feel at corner entry and better drive on corner exit
  • Owners who want broader tuning range than a basic OEM-style shock

Shock design & features

  • STX 46 Supersport rear mono-shock design
  • Gas-pressurised damping with oil/gas separation to help maintain damping consistency
  • Race-proven internal valving approach aimed at traction and control

Tuning controls

  • Rebound damping adjustment
  • Compression damping adjustment

Before you install

  • Confirm compatibility with your KTM RC 390 model and year before fitting
  • Set sag and baseline damping after installation to suit your weight, tyres and typical riding conditions
  • Inspect linkage and mounting hardware condition during install to ensure accurate shock performance

Serviceability/lifecycle

Like all performance shocks, periodic servicing helps keep damping consistent and components in good condition. Service intervals depend on use, especially if the bike sees frequent track time.
