DescriptionThe whole story▼

The Street Triple 675 put Triumph's triple engine into a stripped-down naked bike, and on a machine with so little bodywork, the headstock area sits in plain sight above the top yoke. Accossato's steering stem nut, the open version, thread M24x1, is the fitting that holds the top yoke down onto the steering stem on the Triumph Street Triple 675, built from 2007 to 2016, machined from aluminium and anodised in a choice of colours.

Key Features

  • Open steering stem nut for the Triumph Street Triple 675, 2007 to 2016
  • One nut per pack
  • Thread M24x1
  • CNC-machined aluminium, anodised
  • Seven colours: blue, green, black, red, silver, titanium, gold
  • Holds the top yoke on the steering stem
  • No German ABE on file; for track use

Construction and Material Quality

Accossato starts from a block of aluminium for this nut, cuts it on CNC equipment and then anodises the finished shape, a process that works colour into the metal rather than laying a coat across the surface. Left open at the centre, the nut shows the end of the steering stem once it is threaded down, rather than hiding it under a solid cap. The thread cut for the Street Triple 675 is M24x1, and Accossato's compatibility note covers the applications it lists, with the part doing the structural job of holding the top yoke against the steering stem.

A Detail at the Headstock

On a naked bike like the Street Triple 675, the top yoke and whatever sits on it are visible every time a rider looks down at the bars, which is not the case on a faired sports bike where a screen or fairing edge hides the same area. Swapping a standard steering stem nut for one of Accossato's colours is a way of carrying a colour theme up to the cockpit without touching anything structural beyond that single fastener. Fitting or removing it is work done at the headstock, which is why it belongs with whoever services the steering head rather than as a casual roadside job.

Fitment and Compatibility

This open nut, thread M24x1, is what Accossato lists for the Street Triple 675 across its 2007 to 2016 production. Anyone fitting it to this bike will find a matching range alongside it: a closed nut sharing the same thread under code SC005, plus a pair of swingarm stand bobbins offered two ways, bare aluminium as ST002 or with a rubber sleeve as ST008.

Road Approval

We hold no German ABE or type-approval documentation for this nut, so it is listed for racing and competition use, a note about the paperwork on file rather than a judgement on the part.

Scope of Delivery

The pack contains one open steering stem nut in the single colour selected at the time of ordering. Torque and adjustment at the headstock should follow the motorcycle's own workshop manual.
