The Ohlins YA435 STX 46 Supersport rear shock is built for riders who want stable, repeatable chassis behaviour from the rear of their Yamaha YZF R1. Developed from Ohlins race-derived architecture, it focuses on controlled damping response and clear feedback. The design uses separated oil and gas to help maintain consistent performance during demanding riding.

Ohlins | Made to race, perfected to ride

STX technology is aimed at delivering predictable traction and support through braking, turn-in and drive. This unit is intended as a high-quality replacement rear mono shock for riders prioritising control and tunability.

Who this shock is for

Suitable for trackday and sporty road riders who want more precise rear-end support and the ability to tune damping to match tyres, riding style and conditions. It’s also a solid choice when you want a serviceable performance shock rather than a throwaway OE-style damper.

Shock design & features

  • Rear mono shock format for Yamaha YZF R1 fitment
  • STX 46 Supersport architecture
  • Oil and gas separation design to support damping consistency under sustained load

Tuning controls

This shock includes external damping adjustments for both rebound and compression, allowing you to balance support, grip and response without internal revalving.

Before you install

  • Confirm clearance and routing around the shock body and adjusters on your specific model and setup
  • Set sag and baseline damping after installation so the adjusters work in the correct range
  • Inspect linkage and bearings while the shock is out to avoid masking handling issues

Serviceability/lifecycle

As a rebuildable Ohlins unit, it can be serviced to restore performance and to suit changes in usage over time. Regular servicing helps keep damping consistent and protects internal wear components.
