The Ohlins YA1492 is a rear TTX 44 shock absorber designed for Yamaha YZ 125/250 2-stroke models. Built around Ohlins’ twin-tube damping concept, it’s intended to deliver consistent control and clear chassis feedback across changing track conditions. This unit is supplied without a spring, allowing spring selection to suit rider weight and use.

Ohlins | Made to race, perfected to ride

TTX architecture is focused on stable damping behaviour and repeatable adjustment changes. It’s a popular format in motocross and enduro where traction, braking support and mid-corner stability matter.

Who this shock is for

  • Riders chasing more controlled rear-end behaviour under braking and acceleration
  • Those who want a shock that can be tuned for different tracks and conditions
  • Owners who prefer selecting a dedicated spring rate rather than using a one-size setup

Shock design & features

  • TTX twin-tube design with oil/gas separation for consistent damping feel
  • Rear mono shock fitment for Yamaha YZ 125/250 2-stroke applications
  • Supplied as a shock unit without spring (spring sold separately)

Tuning controls

  • Compression damping adjustment
  • Rebound damping adjustment

Before you install

  • No spring is supplied; a compatible spring from the specified series is required (see notes)
  • Use the recommended Ohlins shock oil as specified for this unit
  • Set sag and baseline damping after fitment to suit rider weight and conditions

Serviceability/lifecycle

This shock is designed to be serviced and revalved as needed. Routine inspection and periodic oil service help maintain damping consistency, especially with regular motocross use.
