The Ohlins KA740 STX 46 Blackline is a rear mono shock developed for the Kawasaki Z900RS range, blending classic appearance with modern damping control. Built around the STX architecture, it uses a gas/oil separated design for consistent performance through changing road conditions. External adjusters let you fine-tune the bike’s balance for comfort, grip and stability without changing the character of the motorcycle.

Ohlins | Made to race, perfected to ride

Blackline components are designed to suit bikes where styling matters as much as function. This unit focuses on controlled damping and predictable chassis behaviour while keeping a finish that complements retro and custom builds.

Who this shock is for

  • Z900RS riders wanting improved ride quality and control on real-world roads.
  • Owners chasing more stability under acceleration and braking without losing a compliant feel.
  • Street and weekend riders who value adjustability for load, tyres and road surfaces.

Shock design & features

  • STX single-tube shock body with gas/oil separation for stable damping behaviour.
  • Mono shock layout intended to work with the standard linkage arrangement.
  • Blackline finish suited to classic and heritage styling.

Tuning controls

  • Rebound damping adjustment to control return speed after bumps and weight transfer.
  • Compression damping adjustment to manage support and impact control.
  • Spring preload adjustment to set ride height and accommodate rider/passenger and luggage.

Before you install

  • Set sag and preload first, then fine-tune rebound and compression in small steps.
  • Check clearances around the reservoir and adjusters during full suspension travel.
  • If you change tyres, load, or riding style, revisit the settings to keep the chassis balanced.

Serviceability/lifecycle

This Ohlins shock is designed to be serviced and revalved by a suspension technician. Periodic oil and seal service helps maintain damping consistency and extends component life, especially in wet or dusty use.
