The Ohlins STX 46 Street rear shock for the Yamaha XV 1900A Midnight Star is built to improve chassis control and ride consistency on real roads. It uses a monotube design with separated oil and gas to help maintain stable damping during sustained use. The result is clearer feedback and more controlled motion through corners and under braking.

Ohlins | Made to race, perfected to ride

Developed from Ohlins racing know-how and adapted for street use, the STX 46 Street range focuses on predictable damping behaviour and practical adjustability. It is intended to deliver a controlled ride without making the bike feel harsh. Fitment-specific valving is aimed at keeping the bike balanced across a range of road conditions.

Shock design & features

This is a monotube rear shock with oil and gas separated for consistent damping and reduced fade. The STX architecture supports stable pressure control and strong damping response, helping the rear tyre track the road more accurately. It is supplied with a fitted spring as listed for the application.

Tuning controls

Adjustability includes rebound damping control. Spring preload is also adjustable to suit rider load and sag targets. These adjustments let you fine-tune how quickly the shock extends after bumps and how the bike sits in its stroke under weight transfer.

Base setup (factory preset)

The shock is delivered with an Ohlins baseline tune intended as a solid starting point for street riding. From there, small changes to rebound and preload are typically used to match rider weight, luggage, and preferred ride feel. If you are unsure where to start, return-to-base is a reliable way to work methodically.

Before you install

Confirm the correct fitment for the Yamaha XV 1900A Midnight Star and inspect linkage/bushings and mounting hardware condition during installation. After fitting, set rider sag with preload first, then adjust rebound to control pogoing and maintain tyre contact. A post-install check for free movement and correct fastener torque is recommended.

Serviceability/lifecycle

Like all performance dampers, this Ohlins unit is designed to be serviced to keep damping consistent over time. Regular oil and seal service helps maintain performance and protects internal components, particularly if the bike sees frequent use or harsh conditions. Servicing also provides an opportunity to tailor the setup if your riding needs change.
