DescriptionThe whole story

The JP ES 020 seals the Streetfighter V4S's secondary air ports with a solid cover, removing one of the few genuinely perishable parts bolted to a cylinder head.

Key Features

  • Ducati Streetfighter V4S (2020–2026)
  • Blanks the secondary air ports in the cylinder head
  • Machined from solid aluminium
  • O-ring sealed, no jointing compound
  • Original fastener positions
  • Standard housing refits at any time

Event-Based Damping

The Öhlins system reacts to chassis behaviour rather than following a fixed map, which is precisely what a naked bike on a bumpy road needs.

Plastic on a Hot Casting

The housing endures the widest thermal swing on the motorcycle. Reeds crack with age rather than mileage, and a cracked reed passes gas the wrong way.

A Cracked Reed's Signature

Soot inside the airbox and an element discoloured well before its interval. It is almost always found while chasing something entirely unrelated.

Two Fasteners, Usually

The housing is held by a small number of bolts into the head, and the cover uses the same ones in the same positions.

Nothing Structural

The housing carries no load and its removal affects no part of the head's sealing or cooling. It is genuinely a bolt-on component.

Heat Cycles, Not Kilometres

A garage queen's reeds age at the same rate as a courier's. Low mileage protects the inside of the motor and does nothing for the plastic bolted to the outside.

Torque, and Why It Matters Here

The fasteners thread into an aluminium cylinder head and Ducati specifies a low figure for good reason. Exceeding it is the commonest way a twenty-minute job becomes a thread repair and a considerably longer weekend, and it is entirely avoidable by looking the number up once.

The Hose Route to the Airbox

It runs from the head up and forward into the airbox, usually clipped at two or three points along the way. Following it before anything is undone shows exactly where the intake end terminates, which is the fitting that has to be closed once the housing is gone.

No Fairing to Hide Behind

Strip the bodywork off a Panigale and everything bolted to the engine becomes part of how the motorcycle looks. On this model the reed housings and their hose sit in plain view above the front cylinder, which is why owners notice them here and never on a faired machine.
