The Ohlins YA042 STX 46 Street rear shock is a dedicated replacement unit for the Yamaha FZ8 (ABS model). Built around Ohlins street-focused STX architecture, it is designed to improve damping control and chassis stability in real-world riding. This unit uses a separated oil/gas design to help maintain consistent damping behaviour as conditions change.

Ohlins | Made to race, perfected to ride

Ohlins applies the same engineering approach used in competition programs to develop street suspension that prioritises predictable feedback. The aim is controlled movement through the stroke, so the tyre can stay loaded and track the road surface. For the FZ8 platform, this means a more settled rear end when you ask more of the bike.

Who this shock is for

Suited to FZ8 riders who want clearer feel from the rear tyre and more composed handling through corners and braking transitions. It is intended for road use where consistency and control matter more than chasing extreme settings. Fitment note: this unit is specified for the FZ8 ABS model only.

Shock design & features

This is an Ohlins STX 46 Street rear mono shock with a gas-pressurised, separated oil/gas configuration. The internal layout is designed to deliver stable damping performance and responsive control over bumps and load changes. It is supplied with an Ohlins spring fitted (01095-44).

Tuning controls

The YA042 provides external adjustment for rebound damping and compression damping, allowing you to tailor the shock to your load, tyres, and preferred ride feel. These controls are intended to let you balance support and comfort without changing hardware.

Before you install

• Confirm the motorcycle is a Yamaha FZ8 ABS model before ordering.
• Inspect linkage and mounting hardware condition during installation, as worn bearings can mask suspension improvements.
• After fitting, set sag and then fine-tune rebound/compression in small steps to match your riding and typical load.

Serviceability/lifecycle

As a fully serviceable Ohlins unit, the shock can be maintained with periodic oil and wear-part replacement to keep damping performance consistent over time. Regular servicing is especially important if the bike sees frequent spirited riding or rough road conditions.
