The Ohlins YA629 STX 46 Street rear shock is built for the Yamaha MT-03 rider who wants clearer feedback and more stable chassis control on the road. Developed from Ohlins race-derived damping concepts, it aims to improve traction and composure when you are braking hard or loading the bike through corners. This is a gas-pressurised, oil/gas separated rear mono shock designed for consistent damping during spirited riding.

Ohlins | Made to race, perfected to ride

STX 46 Street products focus on controlled, predictable damping with a practical feature set for street use. The YA629 is tailored as a rear mono shock application for the MT-03 platform.

Who this shock is for

  • Riders chasing better rear-end stability and grip on the street
  • Owners who want more confidence mid-corner and on corner exit
  • Anyone looking to tune feel and control beyond a basic replacement shock

Shock design & features

  • Gas-pressurised damping system to help maintain consistent performance
  • Oil/gas separated architecture for stable damping behaviour
  • Race-proven valving approach aimed at improving traction and chassis control

Tuning controls

This rear shock provides rebound damping adjustment to refine how quickly the rear returns after bumps and weight transfer. It also includes spring preload adjustment to set ride height and support for rider load and riding style.

Before you install

  • Confirm fitment for Yamaha MT-03 and that the bike uses a rear mono shock configuration
  • Set sag and preload first, then fine-tune rebound to match your tyres, roads, and pace
  • Inspect linkage bearings and mounts during installation to ensure the shock can work as intended

Serviceability/lifecycle

Like all performance dampers, periodic servicing helps maintain damping consistency and seal life. Using the recommended Ohlins shock oil and keeping the unit clean will support long-term performance.
