DescriptionThe whole story▼

The Urban G/S recreates the look of the original R 80 G/S, with a small screen above the headlight and a single clock behind it. From the seat, the top yoke and its steering stem nut sit just below that clock. The Gilles ACMA replaces the nut with a milled, anodised aluminium part.

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

A tribute with a modern detail

The white paint of the G/S tribute takes a red or blue accent easily, and black suits any colour. Gilles lists the ACMA for the Urban G/S of type 1N12 from 2017 to 2020 and for the RN12 from 2021, the same nut for both.

Road Approval

For the BMW R nineT Urban G/S, Gilles states that the ACMA does not require any approval. There is no certificate to carry; fit it to the specified torque and check the steering afterwards.

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.
