DescriptionThe whole story▼
The R6 has carried Yamaha's 600cc supersport flag through more than one generation, and Accossato lists this open steering stem nut across a wide span of that history, 2006 to 2017, including the 50th Anniversary and Limited Edition versions of the bike. Thread M28x1, machined from aluminium and anodised, it holds the top yoke down against the steering stem.
Key Features
- Open steering stem nut for the Yamaha R6, 2006 to 2017
- One nut per pack
- Thread M28x1
- 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
This open nut begins life as aluminium bar stock before Accossato's CNC equipment cuts it to shape and an anodising bath sets the colour into the surface. The open centre leaves the steering stem visible once the nut is wound down, a detail that marks it apart from the closed version. Accossato cuts the thread to M28x1 for the R6, across the long span of applications it lists, with the fitting's role being to clamp the top yoke against the steering stem.
A Detail That Outlasts One Generation
Because Accossato's listing for this nut spans more than a decade of R6 production, the part has fitted riders on very different versions of the same supersport machine, from early examples through to the special editions Yamaha released along the way. That long span means the nut has become a familiar upgrade among R6 owners rather than something tied to a single model year, often fitted as part of a broader refresh when an older R6 changes hands. Any work at the steering head should still follow the motorcycle's own workshop manual. Even on a bike bought secondhand with an unclear service history, a steering stem nut like this is a visible sign that someone has taken the time to look after the small details.
Fitment and Compatibility
Open-nut fitment for the Yamaha R6, 2006 to 2017, sits under this listing at thread M28x1. Accossato's closed alternative for the same headstock is SC001, and the R6's swingarm takes stand bobbins either bare, ST001, or rubber-sleeved, ST006.
Road Approval
We hold no German ABE or type-approval documentation for this nut, so it is listed for racing and competition use rather than for road registration.
Scope of Delivery
The pack contains one open steering stem nut in the single colour selected at the time of ordering.
