DescriptionThe whole story

The JP ES KIT03 deletes the RSV4's secondary air system completely: the electrical eliminator and both head blanks together.

Key Features

  • Aprilia RSV4 (2009–2026)
  • Both halves of the secondary air deletion
  • Solenoid eliminator plus the head blank
  • One part number, one fitting session
  • No drilling and no splicing
  • Every standard part refits afterwards

Two Cylinder Banks

The V4 carries the arrangement on each head, so the kit contains two blanks alongside the electrical eliminator. Closing one bank achieves nothing measurable.

Why the Complete Set

An open port with a silenced controller is one compromise and a blanked head with a warning lamp is another. The kit exists because neither half is useful alone.

Fairing Off First

Reaching the tank on a faired bike means panels off, which is precisely why doing both halves in one session is worth the difference here.

The Sequence

Panels, seat, tank, hoses, housings, blanks, connector. Nothing has to come off twice.

Eighteen Model Years

Aprilia has kept the same architecture current since 2009 and the secondary air arrangement across all of it, so one kit serves the entire run.

Before the Dyno

Air entering after combustion moves every lambda reading a run produces. Serious mapping starts with the system gone rather than merely disconnected.

Nothing Drilled

Aprilia's own connector, fastener positions and torque figures throughout the whole job.

An Adjustable Chassis

Rake, swingarm pivot and engine position all move on an RSV4. It is a race chassis sold with lights on it, which is why so many end up prepared.

Homologation

The system is part of the bike's approval and removing it ends road legality across Europe.

Reversible

Keep the housings and the plug and the motorcycle returns to standard specification.

Variable Intake Trumpets

Aprilia varies the length of the intake stacks with engine speed, which is how the V4 has both a usable midrange and a competitive top end without variable valve timing. It is a genuinely clever piece of engineering and it has been there since 2009.
