DescriptionThe whole story

More Ninja 400s reach a race paddock than almost any other current Kawasaki, and on a bike being prepared for a supersport class the secondary air system is one of the first things off it.

Key Features

  • For the Kawasaki Ninja 400, 2018–2024
  • Bypasses the PAIR solenoid circuit electronically
  • Valve, hoses and reed valves can all be removed
  • Plug-and-play on the factory connector
  • No remapping, no diagnostic reset
  • Standard hardware refits at any time

The Entry Class Runs on These

Supersport 300 and its national equivalents are full of Ninja 400s, and a class with tight technical rules pushes teams towards the work that is still allowed. Stripping the secondary air system is on that list because it takes weight and plumbing off without touching anything the scrutineer measures.

Small Engine, Visible Hardware

On a 399 cc parallel twin the solenoid and its hoses take up a noticeable share of the space above the head. What is a minor tidy-up on a litre bike is a real gain in access here — the airbox comes off more easily afterwards, which matters when the filter is a between-sessions job.

The ECU Checks for It

The solenoid is a driven component: the control unit energises the coil and looks for a response. Unplug it and the diagnostics log an open circuit within seconds. This part reproduces the coil electrically so the check passes and the hardware can leave the bike.

Fitment

  • Kawasaki Ninja 400 (2018–2024)

Road Approval

None. The secondary air system is emissions equipment covered by the motorcycle's type approval. Closed-circuit and race use only.
