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.
