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.

Öhlins Motorcycle Suspension Warranty

New Öhlins motorcycle shock absorbers, front forks and cartridge kits supplied by Teknik Motorsport are covered by the applicable Öhlins manufacturer’s warranty against defects in materials and workmanship.

Teknik Motorsport is an authorised Öhlins Service Centre and administers warranty claims in accordance with the Öhlins warranty conditions. The service intervals below form part of the maintenance requirements for Öhlins products supplied and supported by Teknik Motorsport.

This warranty is in addition to the consumer guarantees that apply under the Australian Consumer Law.

  • Registered motorcycles — non-competition road use Five years, subject to correct application, installation, setup and servicing every: 20,000 km or two years, whichever occurs first.
  • Registered motorcycles — adventure and light off-road use Five years, subject to correct application, spring rate, setup and servicing every: 10,000 km or annually, whichever occurs first.
  • Unregistered or competition motorcycles Two years for eligible Öhlins MX and Enduro products, subject to inspection every ten hours and servicing every: 30 operating hours or annually, whichever occurs first.

Compliance with the applicable service interval is a condition of the Öhlins manufacturer’s warranty. Evidence of servicing may be required when a warranty claim is assessed.

A seal leak, loss of damping performance or internal wear arising after the prescribed service interval has been exceeded will be treated as a service or maintenance issue rather than a manufacturing defect.

Warranty repairs

Öhlins suspension products are designed to be serviced and repaired. Where a warranty claim is approved, the normal remedy is repair of the customer’s original suspension unit using genuine Öhlins replacement parts.

Replacement of a complete shock absorber, fork or cartridge kit is not automatic and would normally occur only where the product has suffered a manufacturing failure that cannot reasonably be repaired. This is at Ohlins discretion. 

Öhlins spare parts and service kits

Öhlins spare parts, seals, bushes, service kits, springs, fluids and individual components are covered only against defects present when supplied.

No fixed age-based warranty applies to wear items, service parts or consumable components. Wear, deterioration, contamination, incorrect installation and damage caused by another component are not manufacturing defects.

Öhlins gives the customer a meaningful five-year warranty on products (Units), provided the suspension is maintained as suspension should be maintained. Teknik supports that warranty locally, can inspect the product properly, and can repair it with genuine parts rather than discarding it.
