DescriptionThe whole story▼
Ducati builds the Panigale V4 R as the homologation model for the Superbike World Championship, which is why it runs a 998 cc engine rather than the larger unit of the road-focused versions. For the 2026 R, Ducabike offers the GS03 steering head nut ring, a single replacement part for the OEM nut. It is produced from solid 7075 aluminium and anodised in colour, and it arrives ready for installation. Riders who keep their R as close to race spec as possible tend to appreciate exactly this kind of clean, purposeful detail.

Road Approval
Ducabike does not provide an ABE or test certificate with this part. It substitutes an original component, so check what is permitted in your country before you take the bike on public roads. On a closed circuit the question does not arise in the same way, but the safety notes on fitting below apply everywhere.
Built in the Spirit of the R
An R is rarely bought as a commuter. It exists so that Ducati can race in WorldSBK, and many owners treat theirs as a road bike with a paddock mindset. A billet-style aluminium nut on the steering head fits that character better than a plain production part. It is the sort of upgrade you would see on a prepared track machine, where every visible fastener looks intentional, and it suits the 2026 V4 R in the garage as well as in the pit lane.
Material
The ring comes from solid 7075, an aluminium grade with a reputation for high strength that is popular in motorsport parts. Its colour is not paint but anodising, which is formed in the surface layer of the metal. Ducabike chose this treatment for enhanced durability as much as for appearance, so cleaning products and handling in the workshop should leave the finish intact.
Installation and Safety
Because the steering head nut is part of the steering, the job is safety-relevant. Leave it to a specialist workshop working to the torque values in the manufacturer instructions, which Ducabike supplies as a PDF in the Downloads tab.
Fitment and Compatibility
This product is assigned only to the Ducati Panigale V4 R of model year 2026, as stated in the Ducabike compatibility list. The base V4 and the V4 S of 2025 and 2026 have their own listings for the same reference.
Colour Options
GS03D in anodised black keeps the cockpit understated and pairs well with carbon. GS03A in anodised red echoes the livery and draws attention to the steering head.
