The Ohlins YA1792 is a rear TTX Flow shock absorber built for Yamaha YZ 125 and YZ 250 two-stroke models. It uses race-derived damping architecture to deliver controlled chassis movement and consistent feel through changing track conditions. 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 is developed for riders who want predictable damping behaviour and clear feedback at the limit. The design focuses on maintaining stability and traction while keeping the rear of the bike composed under load.

Who this shock is for

Suited to motocross and off-road riders on YZ two-strokes chasing more control in acceleration bumps, braking zones, and corner exit. It is also a practical choice if you want a shock that can be tuned around track conditions and rider preference rather than living with a one-size setup.

Shock design & features

This shock uses a gas-pressurised, oil/gas separated design to help maintain consistent damping during hard use. The TTX Flow architecture is aimed at delivering stable damping response and improved rear-wheel connection to the ground.

Tuning controls

External damping adjustments are provided for both compression and rebound, so you can balance hold-up, traction, and recovery speed to match the track and tyre. These adjusters are intended to make setup changes repeatable without disassembling the shock.

Before you install

No spring is supplied with this unit; the spring is sold separately, with a spring series noted for selection. Confirm correct spring choice and installation details before fitment, and plan your setup around rider weight and intended conditions.

Serviceability/lifecycle

Like any performance shock, regular servicing helps keep damping consistent and protects internal components. Periodic oil and seal maintenance is recommended, using the specified Ohlins shock oil listed for this unit.
