The Ohlins KT1790 STX 46 MX is a rear mono shock for the KTM 85 SX, developed from Ohlins motocross racing experience. It’s built to deliver consistent damping feel and clear chassis feedback through changing track conditions. This unit uses a gas-pressurised, oil/gas separated design to help maintain stability during repeated hard hits.

Ohlins | Made to race, perfected to ride

STX motocross shocks are engineered to keep the rear of the bike composed under acceleration, braking and corner entry. The focus is on control and consistency so you can tune the bike around your riding style and track layout.

Who this shock is for

Suited to KTM 85 SX riders chasing a more controlled rear end feel for motocross use. It’s a good fit when you want more tuning range than stock and a shock designed to handle the repeated load cycles of MX riding.
