DescriptionThe whole story▼

An XR rider spends long days looking over a wide bar at the dashboard and the top yoke in front of it. Whatever sits in the middle of that yoke is seen for every kilometre of a tour, and on the standard bike it is simply a nut. The Gilles ACMA makes it a milled, anodised aluminium 7075 part.

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

Which XR

Gilles lists the ACMA for the first XR, type K10 from 2015 to 2019, and for the current SX99 from 2023. The bikes built from 2020 to 2022 are not in Gilles' list, so this product covers only those two generations; the type is in field D.2 of your registration document.

Road Approval

Gilles marks the ACMA as free of registration on the BMW S1000 XR. 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

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.
