DescriptionThe whole story

The JP ES KIT14 clears the ZX-4 RR's KLEEN system completely, with both halves supplied together.

Key Features

  • Kawasaki ZX-4 RR (2024–2026)
  • Both halves of the secondary air deletion
  • Solenoid eliminator and cylinder head cover
  • One part number, one fitting session
  • No drilling and no splicing
  • Every standard part refits afterwards

Sold as a Novelty, Kept as a Bike

Buyers came for the four-cylinder sound and stayed because the ZX-4RR turns out to be genuinely quick on a tight road.

Nothing Else Like It

No other manufacturer sells a four-cylinder 400 sports bike. Kawasaki has the category entirely to itself and appears content to keep it.

Nothing Drilled or Spliced

Kawasaki's own connector and fastener positions throughout the whole job, with the original torque figures observed at every point.

Half a Job Is Worse

Cover the head with the circuit live and the panel complains. Silence the circuit with the head open and a cracked reed still passes gas towards the filter.

The Complete Path

From the airbox, through the reed assembly, into the exhaust port, with a monitored solenoid controlling the lot. The kit accounts for all of it.

The Older the Bike

Reeds age with heat cycles rather than mileage, so any Kawasaki past its first decade is a stronger candidate regardless of the distance covered.

A Complete Job Is Worth More

A half-finished deletion is harder to explain to a buyer than either a standard motorcycle or a properly converted one. It is worth finishing.

The Parts Are Worth Keeping

A complete standard arrangement takes almost no shelf space and turns an inspection or a sale from a problem into an evening's work.

Fifteen Thousand Revolutions

An engine that lives this high puts more heat cycles through everything bolted to the cylinder head than a large twin ever will. The reed housing on a hard-ridden ZX-4RR is working considerably harder than the same part on a Versys.

A Bidirectional Quickshifter

Standard on the RR and used constantly, because an engine that lives above ten thousand revolutions asks for a gearchange more often than most.
