The Ohlins YA910 STX 46 Street rear shock is built to improve rear-end control and ride quality on the Yamaha XVS 950A Midnight Star. It uses a gas-pressurised, oil/gas separated design to help maintain consistent damping through changing road conditions. The result is more predictable chassis behaviour and clearer feedback when the pace or load changes.

Ohlins | Made to race, perfected to ride

Ohlins street shocks take the same damping principles used in competition and apply them to real-world riding. The focus is stability, traction and control rather than harshness. This unit is intended as a quality replacement that brings more tunability than a basic OE-style shock.

Shock design & features

  • STX 46 Street series rear shock for street use
  • Gas-pressurised, oil/gas separated architecture to support consistent damping
  • Developed to improve chassis stability and rear tyre contact on-road

Tuning controls

  • Rebound damping adjustment
  • Spring preload adjustment

Is it right for you?

  • Suited to riders chasing a more controlled, planted feel from the rear of the bike
  • Ideal if you want simple, meaningful adjustability without overcomplicating setup
  • A good match for riders who vary loads or road pace and want to tune rebound and ride height via preload

Before you install

  • Confirm fitment for Yamaha XVS 950A Midnight Star and check clearances around the shock area
  • Set sag and preload first, then fine-tune rebound damping to suit your roads and riding style
  • If you change spring rate or carrying load significantly, plan on rechecking your setup

Serviceability/lifecycle

Like other Ohlins units, the YA910 is designed to be serviced to keep performance consistent over time. Periodic maintenance helps restore damping quality and extends service life, especially if the bike is ridden regularly or in harsh conditions.
