The Ohlins TTX Flow DV rear shock for the Yamaha YZ 250F is built to deliver controlled, repeatable damping across changing track conditions. It uses a pressurised, oil/gas separated design to help maintain consistency as temperatures rise. Designed around independent damping circuits, it supports precise setup without relying on vague “one-size” adjustments.

Ohlins | Made to race, perfected to ride

Ohlins motocross shocks are developed with a focus on damping stability, traction and chassis balance. The TTX Flow DV platform is aimed at riders who want clear feedback and predictable response as the pace increases.

Shock design & features

This unit is based on an oil/gas separated architecture to help reduce aeration and damping fade in demanding use. The TTX Flow DV layout is intended to maintain control through repeated high-load hits and continuous chop, while keeping the rear of the bike settled under acceleration and braking.

Tuning controls

The shock provides external damping adjustment for compression and rebound, allowing changes to support, traction and chassis attitude. Spring preload is set via the preload rings, and the appropriate spring is selected separately as noted for this model.

Before you install

• Confirm fitment for Yamaha YZ 250F and check clearance around linkage and reservoir areas during full travel.
• This shock is supplied without a spring; select from the spring series specified in the notes for correct rate and rider weight.
• If you are fitting a preload adjuster, ensure compatibility with this shock as per the notes.

Serviceability & lifecycle

As with any high-performance motocross shock, regular oil and seal service is important to maintain damping consistency and protect internal components. Service intervals should be based on hours and riding conditions, with shorter intervals for sand, mud or frequent racing.

Is it right for you?

This shock suits riders chasing consistent damping and tuneability on the YZ 250F, particularly when stock suspension struggles with heat build-up or maintaining traction late in a moto. If your priority is simple adjustability with a broad setup window, the independent compression and rebound control is a practical advantage.
