Headstock Nut Working Loose
Owner/reviewer report (not Voge-verified). RiDE Magazine's long-term test reported the headstock nut backing off during normal riding. Single-source so far, but safety-relevant - worth adding a periodic torque check to your inspection routine.
Source: owner/reviewer reports. The loosening report comes from RiDE Magazine, not a Voge service bulletin. The DS900X manual references below describe the steering assembly; they do not establish the cause of the reported problem.
What was reported
RiDE Magazine reported a loose headstock nut during its 3,400-mile long-term test of the 2024 DS900X. The report does not establish which of the steering assembly’s fasteners was affected or why it loosened. Bearing settling should not be presented as a confirmed cause.
The DS900X has its own documented steering fasteners and adjustment instructions. The English owner’s manual, on PDF page 89 (printed page 85), distinguishes the two M35×1 steering-stem locking nuts from the separate M28×1 locking fastener at the upper yoke. The two-piece preload instruction is not a torque setting for every nut in that assembly.
The owner’s manual gives the two-piece wording previously used on this site: loosen the first piece by 1/4 turn at 5.0 N·m, then fasten it to 35 N·m; the second piece is 2 N·m, with the groove aligned.
The DS900X manuals disagree: The chassis workshop manual, on PDF page 39 (printed page 33), labels the lower/upper locking-nut row M26 and prints 50 ± 5 N·m, a 45° return, 35 N·m, and 2 N·m. This differs from the owner’s manual in both thread size and adjustment wording. We cannot verify the reason for the difference. Have the dealer identify the affected fastener and confirm the applicable procedure before tightening it.
How to check it yourself
The DS900X chassis workshop manual, on PDF page 41 (printed page 35), describes checking for steering-bearing play by keeping the motorcycle upright on a stand and pulling the front wheel in the directions shown in its illustration.
A clunk or detectable play needs inspection; it does not, by itself, prove that a particular nut has loosened. If you notice play, stiffness or notchy steering, have the steering assembly checked before continuing to ride. Do not use another model’s preload procedure.
What to do if you find it loose
Contact your dealer and describe what you found. Ask them to identify the loose fastener, inspect the steering bearings and confirm the correct DS900X procedure. If the bike is under warranty, ask whether the inspection and repair are covered.
Bring the RiDE article as background. The DS900X torque reference reproduces the owner-manual preload wording; the workshop-manual disagreement above still needs to be resolved for the bike being repaired.
