DescriptionThe whole story▼

Kawasaki's ZX-10R has raced in World Superbike for many years, and the road bike has always had a top yoke that race mechanics would recognise. The steering stem nut in its centre is the part the rider stares at while the bike sits on its stands in the pits. The Gilles ACMA gives it a coloured replacement.

Key Features

  • M28 x 1.0 thread
  • Not for rear wheel or swingarm axles (Gilles)
  • Colours: black, blue or red
  • Designed exclusively as a steering head nut
  • Aluminium 7075, anodised
  • No registration required, according to Gilles

No green, by design

The ACMA comes in black, blue or red, so a green nut is not an option: black gives a factory look, red a strong contrast. Gilles lists it for the ZXT00J from 2011, the ZXT00S from 2016, the ZXT02L from 2021 and the new ZXT03A from 2026; the last two include the RR.

Road Approval

Gilles marks the ACMA as free of registration on the Kawasaki ZX-10 R. The nut is a direct replacement, and nothing is entered in the vehicle documents.

Scope of Delivery

A single ACMA nut in aluminium 7075, thread M28 x 1.0, colour as selected.

Fitting

Use a torque wrench and the value from the service manual. Gilles designed the ACMA for the steering head only; it must not go on a wheel or swingarm axle.
