DescriptionThe whole story▼

The 2026 GSX-R1000R is already in Gilles' list for the ACMA. Like the GSX-R superbikes before it, it puts clip-ons below the top yoke, so the steering stem nut sits in the rider's line of sight whenever the head comes up from the tuck. The ACMA gives it a milled, anodised aluminium nut.

Key Features

  • M28 x 1.0 thread
  • Not for rear wheel or swingarm axles (Gilles)
  • Aluminium 7075, anodised
  • Patented pin-interlock anti-twist lock, taken over from the ACM axle nut
  • Colours: black, blue or red
  • No registration required, according to Gilles

New bike, established part

The ACMA is the same design Gilles lists for the older GSX-R 1000 generations, with the patented pin-interlock lock that keeps the nut from turning. Blue matches Suzuki's racing tradition, red or black suit the other colour schemes.

Road Approval

Gilles lists the ACMA as not requiring registration on the Suzuki GSX-R1000R: no inspection and no entry in the vehicle documents. Because it sits on the steering head, the correct torque is the part that is not optional.

Scope of Delivery

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

Fitting

The ACMA replaces the nut on the top yoke. Tighten it to the torque the motorcycle manufacturer specifies for the steering stem nut and check the steering for free movement afterwards. If you are unsure, let a workshop do it.
