The Ohlins YA580 STX 46 Blackline rear shock is built to improve control and ride quality on the Yamaha MT-09 (FZ-09) without changing the bike’s core character. It uses a modern damping layout with a Blackline finish suited to understated, factory-plus builds. Setup is straightforward, with external adjusters to tailor support and comfort to your riding.

Ohlins | Made to race, perfected to ride

STX technology is designed to give consistent damping behaviour across real-world road use. The Blackline series pairs that performance focus with a durable, dark finish that suits a wide range of styling directions.

Who this shock is for

Suited to riders who want a more settled rear end under braking and acceleration, with better comfort over imperfect roads. It’s also a good match if you regularly change load (solo vs luggage) and want a shock that can be tuned accordingly.

Shock design & features

This is a rear mono shock from the Ohlins STX 46 Blackline family. It uses a separated oil/gas design to help maintain damping consistency during longer or more demanding rides.

Tuning controls

Adjustment is provided for spring preload, rebound damping, and compression damping. These controls let you balance support, grip, and comfort to suit your tyres, road conditions, and riding style.

Before you install

Confirm fitment for your exact model and year, and set sag and damping from a known baseline before making changes one at a time. If you’re changing tyres or typical load, revisit setup to keep the chassis balanced.

Serviceability/lifecycle

Ohlins shocks are designed to be serviceable, with periodic maintenance helping keep damping performance consistent over time. Servicing intervals depend on usage and conditions, especially if the bike sees frequent wet, dusty, or aggressive riding.
