The Ohlins STX 46 MX rear shock for KTM 85 SX models (2014–2019) is built for motocross use where consistent damping control and clear chassis feedback matter. It is a gas-pressurised, oil/gas separated design intended to maintain performance through repeated impacts and heat. This unit is supplied without a spring, allowing you to select the correct rate for rider weight and use.

Ohlins | Made to race, perfected to ride

Developed from Ohlins motocross racing experience, the STX 46 MX platform focuses on traction, stability and predictable response when the track gets rough. It is designed to support confident cornering, braking and acceleration on smaller-capacity MX bikes.

Shock design & features

• Rear mono shock absorber for KTM 85 SX fitment across the listed year ranges
• Gas-pressurised architecture with oil/gas separation for consistent damping behaviour
• STX 46 MX family construction aimed at durability and serviceability in motocross conditions

Tuning controls

This shock provides external damping adjustments for both compression and rebound, allowing you to balance support, traction and comfort to suit track conditions and riding style. The separate adjustment functions help you tune braking stability and corner-exit drive without needing internal modifications for basic changes.

Before you install

• No spring is supplied; a suitable spring is sold separately (see product notes).
• Confirm fitment to your KTM 85 SX model and year range before installation.
• Plan a baseline setup after fitting to suit the chosen spring rate and rider needs.

Serviceability & lifecycle

As an Ohlins motocross shock, it is designed to be maintained and re-serviced as part of regular race and practice schedules. Routine servicing helps keep damping consistent and components in good condition over time.

Is it right for you?

This unit suits riders wanting a higher level of adjustability and more controlled damping response from the rear of their KTM 85 SX. If you are selecting a spring for the first time or changing riding conditions often, the independent compression and rebound adjustments make it easier to tailor the bike’s balance.
