The Ohlins YA443 STX 36 Twin shock is a rear suspension upgrade designed for the Yamaha SR 400. Built around Ohlins twin-shock architecture, it focuses on consistent damping control and clear chassis feedback on the road. The design uses a gas-pressurised damper to help maintain stable performance as conditions change.

Ohlins | Made to race, perfected to ride

Ohlins street shocks are developed using the same core damping principles found in competition products, then refined for real-world riding. The aim is predictable grip, stability and control rather than a harsh ride.

Who this shock is for

  • SR 400 riders wanting more controlled rear support and improved stability over varied road surfaces
  • Riders who value tunability to suit riding style, load, and tyre choices
  • Owners upgrading ageing or tired rear shocks to restore consistent damping behaviour

Shock design & features

  • STX 36 Twin rear shock configuration for twin-shock applications
  • Gas-pressurised damping system to help reduce fade and keep damping consistent

Tuning controls

  • Rebound damping adjustment

Before you install

  • Confirm fitment for Yamaha SR 400 and twin rear shock mounting prior to installation
  • Set sag and check clearances after installation, then fine-tune rebound to match your roads and load

Serviceability/lifecycle

Like all performance dampers, periodic servicing helps maintain damping consistency and seal life. Keeping the unit clean and inspecting for leaks or damage will support long-term performance.

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.
