DescriptionThe whole story▼

The GSX-R 1000 has worn Suzuki's blue and white racing colours for decades, and its cockpit is laid out like a race bike's: clip-ons under the top yoke, the steering stem nut in the middle. The Gilles ACMA replaces that nut with anodised aluminium 7075, and blue is the colour that matches.

Key Features

  • M28 x 1.0 thread
  • Not for rear wheel or swingarm axles (Gilles)
  • Patented pin-interlock anti-twist lock, taken over from the ACM axle nut
  • Colours: black, blue or red
  • Designed exclusively as a steering head nut
  • No registration required, according to Gilles

WVCY and WDM0

Gilles lists the ACMA for the WVCY of 2012 to 2016 and the WDM0 of 2017 to 2025, including the R and the RZ. Gilles photographed the red version on a Suzuki, which shows the alternative for bikes in other colours.

Road Approval

No registration required, says Gilles: the ACMA replaces the nut on the Suzuki GSX-R 1000's top yoke without an inspection and without a change to the vehicle documents.

Scope of Delivery

One ACMA-28-10 steering stem nut in your chosen colour.

Fitting

Work on the steering head needs care: support the bike, remove the original nut, fit the ACMA and bring it to the manufacturer's torque. The steering must turn freely from lock to lock without play.
