The Ohlins YA921 is a rear twin-shock unit from the STX 36 family for the Yamaha V-Max. It is built around a monotube architecture aimed at consistent damping behaviour and predictable chassis support. This model uses an emulsion oil/gas layout.

Ohlins | Made to race, perfected to ride

Ohlins street shocks are developed with a focus on damping control, tyre contact and stability across real-world road conditions. The YA921 is intended to provide clear feedback and maintain composure as loads change through acceleration, braking and cornering.

Who this shock is for

Suited to V-Max riders wanting improved ride control and a more supported rear end from a quality aftermarket twin-shock setup. It’s also relevant if you want a suspension unit designed to be tuned to your bike and riding style.

Shock design & features

This is a twin rear shock configuration from the Ohlins STX 36 Twin range. The damping system is gas-pressurised in an emulsion design, helping maintain damping consistency as the shock works through repeated movements and temperature changes.

Tuning controls

This shock provides rebound damping adjustment and spring preload adjustment, allowing you to balance ride comfort, support and chassis attitude for your typical load and riding conditions.

Before you install

Confirm the supplied springs and baseline settings match your current rider weight and how the bike is used (solo, pillion, luggage). After installation, set sag and verify full clearance through suspension travel before final tightening and road testing.

Serviceability/lifecycle

As an Ohlins unit, the YA921 is designed to be serviced to keep performance consistent over time. Periodic maintenance helps restore oil condition and damping performance, especially if the bike is ridden regularly.
