DescriptionThe whole story

The JP ES 043 caps the M1000RR's cylinder head ports with covers turned from solid aluminium.

Key Features

  • BMW M1000RR (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

The Mechanical Half

Reed housings bolted to the head with a hose from the airbox. An electrical eliminator satisfies the controller and leaves all of this exactly where it was.

A Race Engine With a Warranty

Titanium rods, a lighter crankshaft and revised heads. The M specification is a homologation build and the emissions plumbing is the one part of it that came from elsewhere.

Machined, Not Moulded

Aluminium turned from solid with the O-ring groove cut in. On a motorcycle assembled from race components, a plastic housing is conspicuous.

A Higher Rev Ceiling

BMW spins the M engine harder than the standard RR, and everything about the intake and exhaust was reworked to suit. Leftover emissions hardware sits oddly with that.

Data-Led Mapping

An engine at this level is set from measurements rather than impressions, and air entering the exhaust after combustion corrupts every one of them.

Original Fastener Positions

BMW's own spacing and torque values, with nothing drilled or tapped in the head.

Both Ports

The covers close the head side completely. The airbox plug closes the other end and the complete kit contains both.

A Hundred and Ninety-Two Kilograms

Wet, with carbon wheels and titanium exhaust. Every component on the bike was weighed against that figure.

Reversible

The standard housings refit on their own fasteners with nothing consumed.

Competition Use

Removing emissions equipment ends road legality where the system is part of the approval.

Built to Satisfy a Regulation

World Superbike requires a road model, and everything about the M1000RR follows from that single requirement. It is the reason a motorcycle this focused is sold with lights, mirrors and a dealer network behind it.
