The Ohlins STX 46 MX rear shock for Yamaha YZ 85 is built for riders chasing consistent damping control and predictable rear-wheel traction on motocross and enduro tracks. Developed from Ohlins competition suspension, it focuses on stability under load and clear chassis feedback. This unit uses a separated oil/gas design to help maintain damping consistency as conditions change.

Ohlins | Made to race, perfected to ride

Ohlins off-road suspension is designed with serviceability and tunability in mind, with a focus on repeatable performance and control. The STX platform is a common choice for riders who want a suspension system that can be set up carefully for rider weight, track conditions and riding style.

Who this shock is for

  • YZ 85 riders wanting a higher level of damping control than stock.
  • Motocross or enduro riders who need a shock that can be tuned for different tracks and levels of grip.
  • Owners planning a proper setup with a chosen spring, as no spring is supplied.

Shock design & features

  • STX 46 MX architecture for rear mono-shock applications.
  • Separated oil/gas design (not an emulsion shock) to support consistent damping behaviour.
  • Designed for compatibility with spring selection as required for the bike and rider.

Tuning controls

  • Rebound damping adjustment.
  • Compression damping adjustment.
  • Hydraulic preload adjustment.

Before you install

  • No spring is supplied; a suitable spring must be selected and fitted separately (refer to the notes in the product data).
  • Confirm fitment for Yamaha YZ 85 and any replacement notes listed for your application.
  • After installation, set sag and damping as part of a complete setup process.

Serviceability / lifecycle

This shock is designed to be serviced and revalved as required. Regular inspection and scheduled servicing will help maintain damping consistency and seal life, especially with frequent riding in mud, dust or high heat.
