The Ohlins YA1390 STX 46 MX is a rear mono shock absorber developed for off-road use where consistent damping control and clear chassis feedback matter. Built around Ohlins race-derived architecture, it’s intended to support stable handling across changing track conditions. Supplied without a spring, allowing spring selection to suit the rider and application.

Ohlins | Made to race, perfected to ride

STX technology is designed to deliver predictable damping behaviour and maintain control as loads and speeds change through a lap. This unit is part of the STX 46 MX family and is configured as a rear mono shock for motocross and enduro-style use.

Who this shock is for

  • Riders wanting a quality rear shock platform with proper external adjustability for track and training days
  • Owners who prefer to select the correct spring separately rather than using a one-rate-fits-all approach
  • Builds where suspension tuning and serviceability are part of the plan

Shock design & features

This shock uses a gas-and-oil separated design with a piston-type reservoir arrangement to help keep damping consistent during demanding use. The STX layout is aimed at maintaining control through repeated hits and heavy braking zones, with a focus on stability and traction.

Tuning controls

External adjustments are provided for rebound damping and compression damping, including separate control for low-speed and high-speed compression. This gives the tuner a practical way to manage balance, grip and bottoming resistance without changing internal parts.

Before you install

  • Spring is not supplied; a suitable spring from the specified series is required (see notes)
  • Confirm fitment and any setup targets before installation
  • Use the recommended Ohlins oil when servicing

Serviceability/lifecycle

Like other Ohlins off-road units, this shock is designed to be serviced and revalved as required. Routine servicing helps maintain damping consistency and protects internal components over time.

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.
