The Ohlins YA367 STX 46 MX is a rear mono shock absorber built for Yamaha YZ 250 and YZ 465 models from 1978 to 1982. It’s designed to deliver controlled damping and consistent handling in motocross conditions where heat and repeated impacts can challenge suspension performance. This unit uses a gas-pressurised design to help maintain damping consistency during longer motos.

Ohlins | Made to race, perfected to ride

Developed from Ohlins racing suspension knowledge, the STX 46 MX platform focuses on predictable chassis behaviour and clear feedback. The aim is stability under braking, support through rough sections, and drive traction as the track changes.

Who this shock is for

  • Motocross riders restoring or upgrading classic Yamaha YZ models within the listed years
  • Riders who want more consistent damping feel through a moto
  • Those looking for external adjustability to tune for track, tyres and riding style

Shock design & features

This is a gas-pressurised rear shock, intended to help reduce fade by keeping the damping system stable as temperatures rise. It is built as a mono shock arrangement for the specified Yamaha YZ fitment and is part of the Ohlins STX 46 MX family.

Tuning controls

Adjustment is provided for both compression damping and rebound damping, allowing you to balance support, traction and recovery speed. This gives practical scope to tune the shock for track roughness, jump landings and braking behaviour without changing internal components.

Before you install

  • Confirm fitment for Yamaha YZ 250/YZ 465 within the stated model years before installation
  • Check linkage and mounting hardware condition so the shock can work freely through its stroke
  • Plan to set sag and confirm spring suitability for the rider and intended use

Serviceability/lifecycle

Like all performance motocross suspension, servicing is part of maintaining consistent damping. Regular oil and seal maintenance helps keep performance stable, especially with frequent riding in dust, mud or high-heat 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.
