The Ohlins YA1892 TTX Flow rear shock is built for Yamaha YZ 125 and YZ 250 2-stroke motocross applications where consistent damping control and clear chassis feedback matter. This unit uses a gas-pressurised design to maintain damping stability through demanding track conditions. Supplied without a spring, it’s intended to be paired with a suitable spring for the rider and use case.

Ohlins | Made to race, perfected to ride

TTX Flow is Ohlins’ motocross shock platform focused on control and repeatability. The YA1892 is a direct-fit rear mono shock option for Yamaha YZ 2-stroke models, aimed at riders who want a more tunable and confidence-inspiring rear end.

Shock design & features

  • Gas-pressurised shock design to support consistent damping behaviour.
  • TTX Flow architecture for controlled oil flow through the damping system.
  • Rear mono shock configuration for the specified Yamaha YZ application.

Tuning controls

This shock provides external adjusters for both compression and rebound damping, allowing you to tune support, traction and recovery speed to suit track conditions and riding style.

Before you install

  • No spring is supplied; select and fit the correct spring (see the referenced spring series notes).
  • Confirm compatibility with your exact model and year before installation.
  • Use the recommended Ohlins shock oil where servicing is required.

Serviceability/lifecycle

Like all performance shocks, this unit benefits from periodic servicing to maintain damping consistency and seal condition. Regular inspection and oil service intervals should match riding frequency and operating conditions.
