The Ohlins YA1992 TTX Flow rear shock is built for Yamaha YZ 125 and YZ 250 2-stroke models where consistent damping and strong chassis control matter most. Developed from Ohlins race technology, it is designed to deliver predictable traction and stability through braking bumps, corner entry and acceleration. This unit is supplied without a spring, allowing the spring rate to be selected to suit rider weight and use.

Ohlins | Made to race, perfected to ride

TTX Flow technology focuses on controlled oil flow through the damping system to help maintain a consistent feel across a wide range of track conditions. The result is a rear shock that supports grip and composure when the pace increases, without relying on vague “one setting fits all” behaviour.

Who this shock is for

  • Motocross riders chasing a more controlled rear end under hard braking and on square-edge bumps
  • Riders who want adjustability to match changing tracks and riding style
  • Owners who prefer to choose the correct spring separately rather than compromise on rate

Shock design & features

This is a gas-pressurised rear shock with separated oil and gas to help maintain damping stability and reduce fade during sustained hard use. The TTX Flow architecture is intended to provide consistent damping response and traction while keeping the chassis settled through rapid load changes.

Tuning controls

Adjustability is provided for rebound damping and compression damping, allowing the shock’s response to be tailored for track roughness, grip level and rider preference. With independent circuits, changes can be made in a controlled way without needing to “chase” settings.

Before you install

  • No spring is supplied; select a suitable spring separately (refer to the noted spring series guidance)
  • Confirm fitment for your exact model and year before installation
  • Use the recommended Ohlins shock oil listed for this unit during service

Serviceability/lifecycle

Ohlins off-road shocks are designed to be maintained and revalved as needed. Regular servicing helps preserve damping consistency and component life, especially in motocross conditions where heat and contamination are high.
