The Ohlins STX 46 Street rear shock for Yamaha XV 1900A Midnight Star is built to improve control and consistency in real-world street riding. It uses a pressurised damping system to help maintain stable damping behaviour as conditions change. Designed as a direct replacement rear unit, it supports more precise setup than a basic OE-style shock.

Ohlins | Made to race, perfected to ride

Ohlins street-focused shock absorbers draw on proven damping architecture to deliver predictable chassis behaviour and clear feedback. The aim is controlled movement rather than harshness, with adjustments that let you tailor the ride to your load and pace.

Shock design & features

  • STX 46 Street rear shock configuration
  • Pressurised damping system for consistent operation
  • Separated oil and gas design (not an emulsion shock)

Tuning controls

  • Rebound damping adjustment
  • Manual spring preload adjustment

Base setup (factory preset)

This unit is supplied with an Ohlins baseline setting intended to be ridden as delivered, then refined to suit rider weight, typical road surface and loading. Start from the factory settings and make one change at a time so you can feel what each adjustment does.

Before you install

  • Confirm fitment for Yamaha XV 1900A Midnight Star and check clearances at full suspension travel.
  • Set sag and preload first, then fine-tune rebound damping to control return speed without packing down.
  • If your bike is used two-up or with luggage, plan on rechecking preload and damping after changing load.

Serviceability/lifecycle

Ohlins shocks are designed to be maintained. Periodic servicing helps keep damping consistent and extends component life, particularly if the bike sees frequent use or rougher roads.
