The Ohlins STX 46 MX rear shock for Yamaha YZ 85 is built for riders chasing consistent damping control and predictable rear-wheel traction on motocross and enduro tracks. Developed from Ohlins competition suspension, it focuses on stability under load and clear chassis feedback. This unit uses a separated oil/gas design to help maintain damping consistency as conditions change.

Ohlins | Made to race, perfected to ride

Ohlins off-road suspension is designed with serviceability and tunability in mind, with a focus on repeatable performance and control. The STX platform is a common choice for riders who want a suspension system that can be set up carefully for rider weight, track conditions and riding style.

Who this shock is for

  • YZ 85 riders wanting a higher level of damping control than stock.
  • Motocross or enduro riders who need a shock that can be tuned for different tracks and levels of grip.
  • Owners planning a proper setup with a chosen spring, as no spring is supplied.

Shock design & features

  • STX 46 MX architecture for rear mono-shock applications.
  • Separated oil/gas design (not an emulsion shock) to support consistent damping behaviour.
  • Designed for compatibility with spring selection as required for the bike and rider.

Tuning controls

  • Rebound damping adjustment.
  • Compression damping adjustment.
  • Hydraulic preload adjustment.

Before you install

  • No spring is supplied; a suitable spring must be selected and fitted separately (refer to the notes in the product data).
  • Confirm fitment for Yamaha YZ 85 and any replacement notes listed for your application.
  • After installation, set sag and damping as part of a complete setup process.

Serviceability / lifecycle

This shock is designed to be serviced and revalved as required. Regular inspection and scheduled servicing will help maintain damping consistency and seal life, especially with frequent riding in mud, dust or high heat.

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.
