Ducati Streetfighter V4 2021 Euro 5 and Dark Stealth colouring

New Dark Stealth coloring and Euro 5 compliance for the Streetfighter V4 S 2021, available in dealers from November 2020.

Borgo Panigale, Bologna, October 23 – For 2021 Ducati presents the Streetfighter V4 S in the new Dark Stealth coloring, which joins the ducati red sportsman. In addition, all models in the Ducati Streetfighter V4 range comply with euro 5 anti-pollution regulations.

The Streetfighter is the result of the “Fight Formula”: the Panigale V4 stripped of the fairings, with high and wide handlebars, 178 kg of weight, Desmosedici Stradale engine 1,100 cm
with 208 hp, kept at bay by biplane wings and a latest generation electronic package. An exaggerated, modern and technological Naked Ducati that immediately enjoyed great success among motorcyclists all over the world, also confirmed by the positive feedback of national and international media.

The Dark Stealth is a modern matte black and represents the perfect color choice to show the aggressive side of the ultra-naked Ducati.

With the arrival of 2021, all motorcycles in the Ducati Streetfighter V4 range become compliant with euro 5 anti-pollution regulations, keeping the maximum power and torque values unchanged, but repositioned at different rotational speeds. The Streetfighter V4 Euro 5 delivers a power of 208 hp (153 kW) at 13,000 rpm (250 rpm higher than the EURO 4 version) and a torque of 12.5 kgm (123 Nm) at 9,500 rpm (2,000 rpm lower than the EURO 4 version). These values, obtained thanks to a new calibration and the new exhaust, make the bike even more enjoyable on the roads all curves.

In order to comply with the new European standard on pollutant emissions, several changes have been made to the desmosedici stradale exhaust line and engine calibration.

The silencer, unchanged from an aesthetic point of view, uses increased catalysts (+10 mm in length) and with a new technology of impregnation of noble metals, fundamental to maximize the ability to convert polluting gases. Lengths and dimensions of rear bank exhaust primarys have been optimized to minimize catalyst ignition time while maintaining engine performance.

Compared to the Euro 4 models, the rear bank manifolds were shortened by 100 mm and reduced in diameter, from Ø 42 mm to Ø 38 mm. The new component has allowed the introduction of a more compact and integrated rear paracalore in the body of the bike. Always in favor of limiting emissions, the introduction of 4 lambda probes, one for each cylinder, which allow a more refined control of the quantities of injected fuel.

All Streetfighter V4 models of the 2021 range then mount new front brake and clutch pumps, both self-purging and derived from those used for the first time on the Superleggera V4. The body of the new pumps has been designed with a configuration that allows a “natural” purge, thus eliminating the need to intervene on the system in the event of air present in the circuit.

The entire Streetfighter V4 range for 2021, including the Dark Stealth coloring for the “S” version, is already orderable in Ducati dealers and will be available from November 2020.
