DescriptionThe whole story▼
The Z400 is the Ninja 400 without the fairing, which means the secondary air hardware above the engine is in plain view every time the tank comes up.
Key Features
- For the Kawasaki Z400, 2019–2023
- Electronic bypass of the PAIR solenoid circuit
- The complete assembly can be removed
- Direct plug on the standard connector
- Shares the circuit with the Ninja 400
- Fully reversible
A Naked Bike Shows Its Plumbing
Kawasaki styled the Z400 around an exposed engine and a visible frame. The hoses running across the head and the solenoid on its bracket are part of what you see, and they are the least considered-looking things on the motorcycle.
A First Bike, a First Job
A2-legal and priced as a first big bike, which means many Z400 owners are doing their own maintenance for the first time. This is a good place to start: it plugs in, needs no setup afterwards, and comes off again if the bike goes back to standard.
The Same Part as the Ninja
Z400 and Ninja 400 share the engine and its solenoid circuit. If both are in the garage — and they often are, in a family or a riding school — one part number covers them.
Fitment
- Kawasaki Z400 (2019–2023)
Road Approval
None. The secondary air system is emissions equipment covered by the motorcycle's type approval. Closed-circuit and race use only.
