CARB Filing Confirms 2027 Ducati Streetfighter V4 SP
Ducati appears to be bringing back one of its most unhinged naked bikes for 2027. A newly issued California Air Resources Board (CARB) Executive Order lists a Streetfighter V4 SP alongside the regular Streetfighter V4 and V4 S, all sharing the same 1,103cc Desmosedici Stradale powerplant. That doesn’t tell us exactly what Ducati has planned, but it does give us an indication that the SP name is returning to the Streetfighter lineup for 2027.
The filing is especially interesting because the current Streetfighter V4 generation arrived in the United States for the 2025 model year after Ducati completely overhauled its Panigale V4 superbike platform. Ducati says the latest Streetfighter V4 and V4 S shares its engine, chassis, and electronics architecture with the Panigale. That also includes the new hollow symmetrical double-sided swingarm, redesigned Front Frame, Brembo Hypure brakes, and Ducati Vehicle Observer electronics.
In other words, a new SP would almost certainly be based on that substantially newer motorcycle rather than simply reviving the previous SP2 with a different paint job.
The Streetfighter SP Has Always Been The Range-Topping Variant
The Streetfighter V4 SP first reached North American dealers in February 2022. It took the already class-leading Streetfighter V4 S and added carbon-fiber wheels, Brembo Stylema R calipers, an STM-EVO SBK dry clutch, machined aluminum rearsets, a lithium-ion battery, and a numbered Winter Test livery. Ducati priced it from $35,500 in the US.
Ducati followed that up with the Streetfighter V4 SP2 for 2023. The formula stayed familiar: 208 horsepower from the 1,103cc Desmosedici Stradale V4, carbon wheels, a dry clutch, Stylema R brakes, Panigale-derived Öhlins suspension settings, and plenty of carbon fiber. The SP2 started at $37,995 in the US, putting it well above the regular V4 S and making its top-tier sporting intentions obvious. This wasn’t the Streetfighter for someone shopping on value.
So What Could The 2027 SP Actually Get?
This is where things get interesting. The CARB document confirms the 1,103cc displacement, but CARB filings don’t reveal suspension, brakes, wheels, bodywork, weight, output, or pricing. Still, Ducati’s previous SP formula gives us a fairly obvious template.
The current Streetfighter V4 S already gets forged aluminum wheels, Öhlins Smart EC 3.0 semi-active suspension, Brembo Hypure calipers, a lithium battery, the hollow symmetrical swingarm, and Ducati’s latest electronics suite. Its Desmosedici Stradale V4 makes 205 horsepower and 88.3 pound-feet of torque with a U.S.-spec tune installed. However, there is plenty of performance being left on the table with the European variants producing a claimed 214 hp at 13,500 rpm and 88.5 lb-ft at 11,250 rpm.
So, an SP would need to go further than that. Carbon-fiber wheels seem like the safest bet given both previous generations. A dry clutch would also make plenty of sense, as would more track-focused Öhlins calibration, lighter components, adjustable rearsets, additional carbon parts, and another numbered special livery. Upgraded brakes are possible too, although the standard bike’s newer Hypure calipers already move the baseline considerably beyond where it was when the original SP appeared.
There’s also a bigger clue sitting elsewhere in Ducati’s lineup. CARB paperwork surfaced earlier this year for a 2027 Panigale V4 SP, which likewise uses the 1,103cc engine. Ducati has historically allowed the Streetfighter SP to borrow heavily from its Panigale counterpart, so whatever hardware eventually appears on the new Panigale V4 SP could give us a very good preview of what the naked version receives.
For now, though, the only thing we can say with certainty is that CARB has certified a 2027 Ducati Streetfighter V4 SP with the same 1,103cc engine family as the V4 and V4 S. Everything beyond that, including carbon wheels, dry clutch hardware, suspension, output, weight, price, and availability, remains speculative until Ducati actually pulls the cover off the thing, which will likely happen in the coming months.
