The Ohlins HO406 STX 46 Supersport rear shock is built for track-focused Honda RS 125 setups that need consistent damping and clear chassis feedback. It uses a gas-separated design to help maintain control during repeated hard use. The STX architecture supports precise tuning for traction, stability and corner-exit drive.

Ohlins | Made to race, perfected to ride

Developed from Ohlins racing experience, the STX 46 Supersport platform is aimed at riders who want predictable behaviour and repeatable setup changes. It is designed to deliver strong support under braking and stable attitude through fast direction changes.

Before you install
