DescriptionThe whole story▼

The MT-10 carries the crossplane R1 engine in a naked chassis with a tubular bar, and the top yoke is left in plain sight behind the headlight unit. The steering stem nut sits in the middle of it. The Gilles ACMA replaces that nut with a milled aluminium 7075 part, anodised black, blue or red.

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

RN45 and RN78

Gilles lists the ACMA for the MT-10 and MT-10 SP of type RN45, built from 2016 to 2021, and for the RN78 from 2022. On a naked bike with this much torque, the pin that locks the nut against turning is a detail worth having.

Road Approval

According to Gilles, the ACMA steering stem nut needs no approval on the Yamaha MT-10. Nothing changes in the papers; tighten it to the manufacturer's value for the steering stem nut.

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.
