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.
