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.
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.Â
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.
