DescriptionThe whole story▼
Two short prototype-style cases under the tail of a Panigale. Spark's Moto GP version of its full titanium V2 system is the most compact of the underseat kits — and, like the Grid-O version, it fits the standard motorcycle.
Key Features
- Full titanium racing system for the Ducati Panigale V2 955/959 and Streetfighter V2, 2016 to 2024.
- Two Moto GP silencers under the seat: round, very short, large outlet diameter.
- Visible TIG-welded collectors and silencers.
- Developed with WSSP teams, from WSBK experience.
- Compatible with the stock motorcycle.
- Same list price as the Grid-O version.
The Shortest Cases Spark Builds
The Moto GP is the most compact silencer in Spark's catalogue — round, very short, with a large outlet diameter chosen to emphasise the engine note rather than absorb it. Under the tail of a Panigale V2, two of them all but disappear.
That is the opposite of what the same silencer does on a naked bike, where a short case is a statement. Here it is the discreet option: the tail keeps its own shape and the exhaust stops being a visible component. What you hear does not follow the same logic.
Same Price as the Grid-O
Spark charges identically for this and for GDU8832T with the Grid-O silencers. The collector, the construction and the restrictions are the same; only the cases differ.
Spark publishes 4.2 kg against a standard 11.6 kg for the Grid-O version of this system and does not give a separate figure for the Moto GP, so we will not invent one. What is certain is that both replace the same 11.6 kg standard exhaust and share the same titanium collector.
What the Layout Costs
Spark lists the same three consequences as for the Grid-O version: the passenger footboards cannot be kept, the lock under the seat becomes inaccessible, and the original radiator fan duct must be modified for installation.
The fan duct is the one to plan for. It is not a bracket change — a duct has to be cut. And to reinstall the original lambda sensors the 0CAVO002 extension cable is required, which is not supplied.
How Spark Built It
The company describes the process rather than only the result: 3D scanning of the motorcycle, 3D drawings, 3D laser cutting for the titanium bushings, and collectors and silencers TIG-welded with the beads left visible.
That combination is unusual. The measurement and the cutting are done to a precision a hand-built part normally cannot claim; the welding is deliberately left as evidence that a person made it. Spark has specialised in Ducati since the beginning, and this kit came out of collaboration with World Supersport teams and experience gained in World Superbike.
Fitment & Compatibility
Ducati Panigale V2 955 and Streetfighter V2 955, 2020 through 2024, and the Panigale 959 from 2016 through 2019, on the stock motorcycle. With Grid-O silencers the system is GDU8832T. The rectangular-silencer versions are GDU8837T and, in WSSP specification, GDU8836T. The 3/4 kit is GDU8850T.
Road Approval
None. The system carries no EC certificate and no catalytic converter. Closed circuits only.
