DescriptionThe whole story

For the 2021 ZX-10RR, the JP CO KA054 replaces the combined throttle housing and right-hand switch block with a single milled Ergal body.

Key Features

  • Kawasaki ZX-10 RR (2021–2025)
  • Integrated right-hand switch block
  • Machined from a single block of Ergal 7075
  • Black or red anodising
  • Plug-and-play on the original connector
  • Replaces housing and switch together

Built to Satisfy a Rulebook

The RR exists because World Superbike requires a production basis for what is raced. Titanium connecting rods, Pankl internals, a lightened crankshaft and a cylinder head machined for race camshafts, produced only in the quantity homologation demands.

Housing and Switches Together

Kawasaki integrated the right-hand controls into the throttle assembly, so both are renewed as one component. This unit is that component, milled from a single billet rather than moulded, using the motorcycle's original connector.

What Play Costs on a Race Bike

The throttle housing holds the position sensor the ECU reads. Any slack between the tube and the body becomes imprecision at the throttle bodies, which on a machine ridden at the limit is felt as vagueness exactly where the rider needs certainty.

Sixteen Thousand RPM

Everything bolted to the handlebar is being shaken continuously at the top of a gear. A one-piece machined body with a bolted clamp stays tight under that; a two-piece moulding clipped around the bar gradually does not.

Two Finishes

Black and red on this part number. Red appears on Kawasaki's own racing schemes as an accent; black is what most competition bikes get, on the reasoning that a cockpit should not catch the eye.

Sealed Against the Paddock

Sealed switch elements inside a body with no moulded seam. Race machines are cleaned hot and stored damp, and it is water ingress rather than wear that ends most switchgear in that setting.

Fitting It

The grip and bar-end weight come off, the original assembly follows, and the new body goes on using Kawasaki's own connector. Nothing is spliced and no coding is required, which keeps the job inside a race weekend rather than requiring a workshop visit.
