Description
Information

The Ohlins YA634 is a rear twin-shock unit from the STX 36 family, built for the Yamaha SR 400. It is a gas-pressurised design intended to deliver consistent damping behaviour and clear chassis feedback. As an Ohlins unit, it is engineered for repeatable control and serviceable long-term use.

Ohlins | Made to race, perfected to ride

Developed from Ohlins racing experience, this twin-shock layout is aimed at riders who want a more controlled, predictable rear end. The focus is on stability, traction and damping consistency during spirited road riding.

Who this shock is for

Suited to SR 400 owners looking for improved damping control over standard suspension, without moving away from the classic twin-shock format. A good match for riders who value feel and composure through corners and under braking.

Shock design & features

This is a gas-pressurised shock, separating the gas and oil to help maintain damping consistency as temperatures change. Ohlins valving is designed to support traction and stability, particularly during corner exit and higher-speed chassis movements.

Tuning controls

The YA634 provides damping adjustment for both compression and rebound, allowing you to tailor response to your weight, riding style and road conditions. With separate circuits for compression and rebound, changes can be made more independently than on simpler shock designs.

Before you install

Confirm the shocks are being fitted as a matched rear pair on the SR 400.
Set sag and baseline damping after installation to suit your load and riding conditions.
If your bike has non-standard geometry or load requirements, plan a tailored setup session.

Serviceability/lifecycle

As a serviceable Ohlins unit, the YA634 is designed to be maintained with periodic oil and wear-part replacement to keep damping performance consistent over time.
