The Ohlins STX 46 MX rear shock for the Kawasaki KX 85 is built for motocross use where consistent damping and clear rear-tyre feel matter most. This unit uses a pressurised design to help maintain stable performance as conditions and pace change. It is supplied without a spring, allowing the correct rate to be selected for the rider and application.

Ohlins | Made to race, perfected to ride

Developed from Ohlins off-road racing experience, the STX 46 MX platform focuses on control, traction and predictable chassis balance. It is intended for riders who want a more tuneable rear end and improved consistency through repeated hard impacts.

Who this shock is for

  • Motocross riders chasing more rear grip and stability on a KX 85
  • Riders who want external adjustment to suit track conditions
  • Setups where selecting the correct spring separately is preferred

Shock design & features

  • Pressurised, oil/gas separated rear shock architecture
  • STX 46 MX construction aimed at maintaining damping consistency during demanding riding
  • Designed as a direct-fit rear mono shock application

Tuning controls

  • Rebound damping adjustment
  • Compression damping adjustment

Before you install

  • Spring is not included; select the correct spring to match rider weight and intended use
  • Confirm all mounting hardware and clearances during installation
  • Plan a baseline setup after fitment, then fine-tune rebound and compression to track 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.
