DescriptionThe whole story

The JP ES 018 B blanks the HP4 Race's secondary air ports in the cylinder head with machined covers.

Key Features

  • BMW HP4 Race 1000 (2017–2018)
  • 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

The Mechanical Half

Reed housings bolted to the head, fed from the airbox. Removing the hose does nothing about them and they stay in place until they are replaced.

Why They Go

Air admitted into the exhaust ports after combustion corrupts any gas analysis, and on an engine built for competition every reading has to describe the engine rather than the plumbing.

Machined Covers

Aluminium turned from solid, sealing on an O-ring against the head. There is nothing inside them to age and nothing to inspect afterwards.

A Carbon Frame

Wound from carbon fibre rather than cast from aluminium, which nothing else sold to the public has ever used. The HP4 Race was a World Superbike machine with a serial number.

Never Road Legal

BMW sold it without a registration document, which removes every question about type approval and explains why the specification could be what it is.

Seven Hundred and Fifty Built

All of them sold, at a price that put the motorcycle beyond almost everybody. They appear on circuits rather than in showrooms and their owners use them.

Original Fastener Positions

BMW's own bolt spacing and torque figures. Nothing is drilled and no thread in the head is cut or disturbed.

The Airbox Side

Blanking the head leaves the hose port open unless the airbox plug is fitted as well. The two parts belong together.

Reversible

The standard housings refit on their own fasteners with no replacement seals required.

A Race Engine

Hand assembled with titanium rods and a race exhaust. Leaving emissions plumbing on it was always going to be temporary.
