The Ohlins TTX Flow DV rear shock for Yamaha YZ 450F is built around consistent damping control and clear rider feedback for motocross use. It is designed to help the rear end track accurately through acceleration bumps, braking zones, and corner exits. This is a rear mono shock supplied without a spring, allowing the correct rate to be selected for the rider and application.

Ohlins | Made to race, perfected to ride

TTX Flow DV is part of Ohlins’ competition suspension range, developed for riders who want predictable response and reliable damping behaviour over a moto. The focus is on maintaining control as conditions change, rather than chasing a single “feel” setting.

Who this shock is for

Suited to Yamaha YZ 450F riders who ride motocross and want a tunable rear shock with a broad adjustment range. It’s a good match when you’re working on balance and traction and want the suspension to respond consistently as the track develops.

Shock design & features

This shock uses an oil/gas separated damping design to help maintain stable performance as temperatures rise. The TTX Flow DV layout is intended to deliver controlled damping action with good sensitivity, supporting traction and stability through varied track inputs.

Tuning controls

External adjustment is provided for rebound damping and compression damping, allowing you to tune return speed and impact control independently. Spring preload is adjustable, and the shock is supplied without a spring so the correct spring rate can be chosen from the referenced spring series in the notes.

Before you install

• No spring is supplied—confirm the correct spring rate and spring series for the rider and bike.
• Check fitment for Yamaha YZ 450F and allow for correct sag setup once installed.
• Use the recommended Ohlins suspension oil noted for this unit during service.

Serviceability / lifecycle

As a rebuildable performance shock, it is intended to be serviced at regular intervals depending on hours and riding conditions. Routine servicing helps keep damping consistent and protects internal components over time.
