New Streetfighter V4

The Fight Formula

The Panigale V4, stripped of its fairings and with high, wide handlebars. This, in short, is the underlying concept of the new Streetfighter V4, a bike that magnifies the thrill of the ride every time it takes to the road.

The result? An unrivalled naked bristling with cutting-edge technology and an awe-inspiring design that oozes pure performance.

The minimalist full-LED headlight captures the spirit of the Streetfighter V4 perfectly. On the one hand, it recalls the front of the Panigale V4 and, on the other, evokes the crazy grin of the Joker (the comic strip character from which the Ducati Style Center drew inspiration for this new Bologna-built naked). Already featured on the Panigale V4 and SuperSport, the V-shaped DRL is another clear Ducati hallmark.

Joker face

The minimalist full-LED headlight captures the spirit of the Streetfighter V4 perfectly. On the one hand, it recalls the front of the Panigale V4 and, on the other, evokes the crazy grin of the Joker (the comic strip character from which the Ducati Style Center drew inspiration for this new Bologna-built naked). 

Already featured on the Panigale V4 and SuperSport, the V-shaped DRL is another clear Ducati hallmark.

The compact headlight is embedded in a meticulously designed dual-layer fairing that incorporates the air-box and LED cooling intakes; a rear deflector, instead, stops flows impacting the tank directly. 

The headlight is surmounted by a 5" TFT screen (the same as the one on the Panigale V4) and features a smartly styled front cover that hides connectors and wiring.

The magic of Aerodynamics

Fast, agile mixed-road performance demands maximum stability at high speed and when braking, reduced wheel-up during acceleration and minimised electronic control of the suspension set-up: that's why Ducati Corse specialists have, together with the Ducati Style Centre, developed biplane wings for the Streetfighter V4.

The aerodynamics were developed using CFD (Computational Fluid Dynamics) simulation. The calculation method involved stationary simulation of flow and pressure to achieve increased downforce, especially on the front wheel.

To reduce lateral protrusion as much as possible, the aerodynamics team decided to adopt a 'biplane' configuration of limited 'wingspan' with upper and lower wings working independently. 

Each appendage can be described as a square-plan mono-wing with a winglet on its outer tip. Moreover, the wings have been positioned as close as possible to the front wheel (near the radiator side panels) to maximise the anti wheel-up effect.

These aerodynamic appendages generate 28 kg of downforce at 270 kph (20 kg on the front wheel, 8 kg on the rear). The wings also help draw heat off the engine by increasing water and oil radiator throughflow speeds by 2% and 10% respectively.

Wing-generated downforce attenuates front wheel 'floating' at high speed and the tendency to wheel-up. It also improves stability during braking at the turn-in point and through the corner.

The aerodynamics thus instil confidence and limit intervention by electronic controls. This helps the rider keep the throttle open longer and brake later going into the bends, providing significant performance benefits.

The low, lunging front end flows out from the tank, giving the Streetfighter V4 the look of a predator coiled for the pounce.

Front Frame

The Streetfighter V4 features the Front-Frame - an offshoot of Ducati's extensive experience in MotoGP - which uses the Desmosedici Stradale engine as a load-bearing member.

Compared to traditional perimeter frames the main lay-out difference is that the engine is used as a structural chassis element. Weighing just 4 kg, the compact Front-Frame is attached directly to the upper crankcase of the front cylinder bank and the cylinder head of the rear bank; the V4 crankcase also provides the rear suspension attachment point and the single-sided swingarm pivot mount.

The key advantage of the Ducati Front-Frame is that it uses the Desmosedici Stradale engine to achieve the desired stiffness: this has resulted in significantly lower main frame length and weight and a better stiffness/weight ratio. Moreover, the struts alongside the engine have been shortened, making bike design more compact, especially in the rider's seat area.

Completing the chassis is the under-seat Trellis subframe, attached to the Front-Frame at the top and bolted to the head of the rear cylinder bank below.

The rear suspension linkage mechanism is attached to the Desmosedici Stradale engine via a forged aluminium bracket. The linkage reacts to movements imparted by a cast aluminium high-truss swingarm.

Steering geometry features a 24.5° rake and 100 mm trail.

High Power

The new Streetfighter V4 is powered by a 1103 cm3 Desmosedici Stradale engine. In this configuration the 90° V4 delivers 208 hp (153 kW) at 12,750 rpm, an unrivalled power level within the naked segment, perfectly in keeping with the all-out character of the new Streetfighter V4. Maximum torque is 123 Nm (12.5 kgm) at 11,500 rpm, practically unchanged with respect to the Panigale V4. Dedicated engine mapping lets riders safely make the most of Streetfighter V4 performance on the road.

The final ratio, shorter than that of the Panigale V4, delivers a wheel torque higher of +10%, which ensures an immediate response to the throttle command.

Power and torque can be raised to 220 hp (162 kW) and 130 Nm (13.2 kgm) by fitting the full-racing Ducati Performance exhaust by Akrapovič that also reduces weight by – 6 kg.

MotoGP-derived engine

The Desmosedici Stradale was designed around the core of the V4 MotoGP engine – the cylinder heads. With the same dimensions and geometry as the Desmosedici GP, the Desmosedici Stradale offers the same outstanding fluid dynamics. It also has the same engine configuration: 90° V4, rotated rearward by 42°. 

This solution makes the engine extremely compact, allowing centralisation of mass and flawless integration with the vehicle.

Racing architecture: road and track

The bore of (81 mm) is the same as that used by the Desmosedici GP engine and is the maximum dimension allowed by MotoGP regulations. It is also the highest in the four-cylinder supersport segment.
The stroke (53.5 mm) is longer compared to the Desmosedici GP engine in order to deliver higher torque on open road use, and to reduce maximum engine rotation speed.


The use of the same bore as the Desmosedici GP engine means that all the fluid dynamics (valves, intake pipes, throttle bodies), which in fact make up the heart of the engine where the performance is generated are also very similar in the two drive units. 

The V4 90° layout makes the engine extremely compact, allowing the centring of the masses and better integration into the bike. In fact, the Desmosedici Stradale has been inserted into the vehicle with the front bank of the cylinders rotated back by 42° with respect to the horizontal plane, as on the Ducati engines competing in MotoGP. This optimises the distribution of weight, allows for the use of more extensive radiators and makes it possible to shift the swinging arm pivot forwards.


Its architecture also generates a natural balancing of first-order forces, without the gain in weight and loss of power of a balance shaft. 

V engine

For Ducati, the V4 layout at 90° is the utmost expression of sportiness for a motorcycle engine. It is no coincidence that it is the same solution used in the MotoGP Desmosedici engines.

Compactness

Compared to a classic in-line four-cylinder, the lateral compactness of the V-engine allows greater centralisation of the masses and makes it possible to limit the weight on the front end of the bike. Furthermore, the shorter crankshaft generates a smaller gyroscopic effect. All these aspects have a positive impact on the bike's dynamics, helping to make it light and fast when changing directions.

Integration of engine and chassis

The optimal integration of engine and chassis is a fundamental concept behind every Ducati project. That is why the Desmosedici Stradale was developed to be mounted rotated backwards by 42°, like the Ducati MotoGP engines, to optimise weight distribution, use more extensive radiators and to shift the swinging arm pivot forwards as much as possible.

Desmodromic system

Like all Ducati engines, on the Desmosedici Stradale the design of the Desmodromic system is a key factor for obtaining top performance. The Desmodromic system in the Desmosedici Stradale uses components that have been completely redesigned and miniaturised to obtain very compact heads, achieving a level of sophistication, compactness and lightness never seen before on a Ducati bike.

Counter-rotating crankshaft

On normal motorcycles the crankshaft rotates in the same direction as the wheels. In contrast, in MotoGP the counter-rotating crankshaft rotates in the opposite direction. The Ducati engine specialists have borrowed this technical solution from the racing models for the same reasons it was applied in the competitive world. In fact, this solution has advantages related to two aspects of physics: the gyroscopic effect and inertia.

"Twin Pulse" firing order

The 70° offset of the crank pins combined with the 90° V-engine layout generates a firing order that Ducati has called "Twin Pulse" because it is as if the engine were reproducing the firing sequence of a twin cylinder. The peculiarity lies in the rapid firing of the two cylinders on the left side and then on the right side of the motorcycle. In the timing diagram, the firings are situated at 0°, 90°, 290° and 380°. This particular firing order gives the V4 a sound that is quite similar to that of the Desmosedici MotoGP.

Magnesium: precious alloy

Magnesium occupies a prominent position among the lighter metal materials. It is not by chance that in alloy form it is widely used in competitions. The Desmosedici Stradale uses magnesium alloy for numerous components, including head covers, oil sump, generator and clutch. A technical choice that also has a positive impact on the bike's look.

Aluminium: durability and lightness

The crankcases are made of aluminium using gravity die-casting and coupled with horizontal cut. The upper casing includes the four aluminium cylinder liners with nikasil coating that ensures low friction and protection against wear.

Weight

The collaboration with Ducati Corse has made it possible to achieve a compact, lightweight and high performance engine. Weighing 64.5 kg, the Desmosedici Stradale is only 2 kg heavier than the 1,285 cm³ twin-cylinder Superquadro.

Pistons

Pistons having a diameter of 81 mm churn in the barrels of the cylinders, with two piston rings, low friction, plus oil scraper ring. They are moulded in aluminium and utilise the "box in box" technology that makes it possible to contain the skirt height and the thickness under the piston crown thus reducing friction and inertia loads while maintaining the required durability and stiffness.

Compression ratio

The compression ratio is 14:1, a high value that once again reflects a design of competitive origin. The pistons are coupled to steel forged rods with a centre distance of 101.8 mm.

DQS Up & Down: changing gears like in a race

The perfect functionality of the six-speed gearbox is enhanced by the Ducati Quick Shift EVO (DQS EVO), which offers a fundamental evolution: changing gears with the throttle open. Furthermore, DQS EVO follows different logics to shift up and down. Integration with the slipper clutch and engine brake (Engine Brake Control) ensures the system's absolute effectiveness even on the track.

Slipper clutch

The wet clutch with progressive control optimally combines high torque drive and rider comfort. In competitive riding conditions, with sudden downshifts and strong engine braking, the slipper clutch counteracts the loss of stability of the rear end, offering excellent control while braking deep in corners.

Semi-dry casing lubrication

Like the MotoGP engines, the Desmosedici Stradale uses a semi-dry casing lubrication with delivery and recovery stages to ensure proper lubrication of all moving parts at all times.

Read more
Cooling system

The water pump, located in the V of the cylinders, is powered by a shaft driven by a cascade of gear wheels. Its location is designed to reduce the size of the circuit as much as possible, improving its efficiency and optimising engine weight.

Air intake is entrusted to four oval throttle bodies (52 mm diameter equivalent) connected to fixed 70 mm long intake horns. Each throttle body has two injectors: a sub-butterfly one for low-load use and another above it that comes into play when maximum engine performance is required. The throttle bodies of each cylinder bank are moved by a dedicated electric motor. 

Thanks to the full Ride by Wire system, this allows complex electronic control strategies and modulation of engine 'feel' according to selected riding mode.

To increase urban riding comfort the rear cylinder bank is deactivated at idle when water temperature exceeds 75°.

Long maintenance intervals

Valve play adjustment (Desmo Service) is required every 24,000 km; services are performed every 12,000 km/12 months.

Ergonomics, more comfort, more control

Compared to the Panigale V4, the riding position - with an above-ground height of 845 mm - has been redefined as per the specifications of a naked model. In keeping with streetfighter culture, the semi-handlebars have been replaced by a high, wide bar that, together with a seat with 60 mm of foam thikness and moderated footpeg position, ensures sports-style comfort during inner city rides and the control needed to tackle country roads or racetracks.

While maintaining many of the Panigale's stylistic features, the tail is supported by a steel subframe and has been redesigned to enhance passenger comfort and give the rider more lengthways space. 

Front Frame

The Streetfighter V4 features the Front-Frame - an offshoot of Ducati's extensive experience in MotoGP - which uses the Desmosedici Stradale engine as a load-bearing member.

Compared to traditional perimeter frames the main lay-out difference is that the engine is used as a structural chassis element. Weighing just 4 kg, the compact Front-Frame is attached directly to the upper crankcase of the front cylinder bank and the cylinder head of the rear bank; the V4 crankcase also provides the rear suspension attachment point and the single-sided swingarm pivot mount.

The key advantage of the Ducati Front-Frame is that it uses the Desmosedici Stradale engine to achieve the desired stiffness: this has resulted in significantly lower main frame length and weight and a better stiffness/weight ratio. Moreover, the struts alongside the engine have been shortened, making bike design more compact, especially in the rider's seat area.

Completing the chassis is the under-seat Trellis subframe, attached to the Front-Frame at the top and bolted to the head of the rear cylinder bank below.

The rear suspension linkage mechanism is attached to the Desmosedici Stradale engine via a forged aluminium bracket. The linkage reacts to movements imparted by a cast aluminium high-truss swingarm.

Steering geometry features a 24.5° rake and 100 mm trail.

Sophisticated suspension

The Streetfighter V4 mounts 43 mm Showa Big Piston Forks (BPF) to provide full adjustability in spring pre-load and compression and rebound damping. 

The fork bodies house chrome sliders with Brembo radial caliper mountings. A Sachs steering damper completes the front-end package. At the rear there is a fully adjustable Sachs shock absorber, one side of which is attached to the Desmosedici Stradale engine via a forged aluminium bracket.

The Streetfighter V4 S, instead, is equipped with an Öhlins NIX-30 fork, an Öhlins TTX36 rear shock absorber and an Öhlins event-based steering damper. On this version suspension and steering damper are controlled by the second-generation Öhlins Smart EC 2.0 system which, among other things, features the new OBTi (Objective Based Tuning Interface).

Wheels and tyres

While the Streetfighter V4 mounts cast aluminium 5-spoke wheels, the V4 S is equipped with 3-spoke Marchesini forged aluminium alloy wheels.

The rims mount Pirelli Diablo Rosso Corsa II tyres. Combining track performance with road versatility, they come in the 120/70 ZR17 (front) and 200/60 ZR 17 (rear) sizes, already used extensively for slick tyres in the FIM Superbike World Championship. 

The rear tyre compound has been designed by Pirelli specifically for the Streetfighter V4. It ensures the same dynamic behaviour as the Supercorsa SP race replica tyres mounted on the Panigale V4, but has better low temperature performance to ensure the versatility one expects from a naked.

Braking system with Brembo Stylema® monobloc calipers

The Streetfighter V4 range features powerful Brembo Stylema® monobloc calipers, developed out of the already high performance M50 calipers.

The dual Brembo calipers, each mounting four 30 mm pistons, bite down on 330 mm discs to give exceptional braking power. Rear braking, instead, relies on a single 245 mm disc clamped by a 2-piston caliper. Braking is aided by the ABS Cornering EVO system, which uses the ultra-light 9.1MP control unit.

Racing tank

As on racing bikes, the 16-litre aluminium tank has a section that extends under the seat. Compared to the Panigale V4, the lower section of the tank has been modified to allow installation of a seat with thicker padding to boost rider comfort. 

Up front, the space not occupied by fuel has been used to house all the electronics, battery included.

MotoGP-derived electronics

The latest-generation electronics package on the Streetfighter V4 is based on a 6-axis Inertial Measurement Unit (6D IMU) which instantly detects the bike's roll, yaw and pitch angles.

The electronics package has controls for every part of the ride: some oversee start, acceleration and braking, others govern traction and others again lend a helping hand on corners and out-of-the-corner stretches. 

  • ABS Cornering EVO
  • Ducati Traction Control (DTC) EVO 2
  • Ducati Slide Control (DSC)
  • Ducati Wheelie Control (DWC) EVO
  • Ducati Power Launch (DPL)
  • Ducati Quick Shift up/down (DQS) EVO 2
  • Engine Brake Control (EBC) EVO
  • Ducati Electronic Suspension (DES) EVO 

Operational parameters for each of these controls are associated by default with the three Streetfighter V4 Riding Modes. Riders can personalise parameters to suit their riding style or restore Ducati factory settings. DTC, DWC, DSC or EBC control levels can be adjusted quickly via the left switchgear.

Second-generation TFT instrumentation

The Streetfighter V4 features the same 5" full-TFT high resolution colour screen (186.59 PPI - 800xRGBx480) as the Panigale V4. The dashboard is dominated by the round virtual rev counter on the right. Desmosedici Stradale revs are displayed on a needle gauge. 

Movement of the latter is accompanied by a white trail that acts as a 'shift light', changing colour from white to orange and then red as the rev limit approaches.

The rider can call up two different lay-outs: 'Track' highlights the lap times and the rev counter scale makes the revs typical of track use more clearly visible; 'Road', instead, replaces lap times with info on the Ducati Multimedia System (DMS), where present, and the rev scale is more appropriate for road use.

Riding Modes

Riding Modes provide users with three different pre-set riding styles so that Streetfighter V4 performance can be adapted to rider, track/route and weather conditions. Changing the Riding Modes instantaneously changes the character of the engine, the electronic control parameters and, on the S version, the suspension set-up too.

ABS Cornering EVO

The ABS system on the Streetfighter V4 features the cornering function (which keeps the ABS working even with the bike leaned over) and has the same intervention logic and control as the Panigale V4. ABS Cornering EVO can be set at three different levels to fully satisfy the needs of all riders, on racetrack or road, even under critical low-grip conditions.

Complete titanium exhaust assembly

Made exclusively by Akrapovič with the Ducati experience. It is the most advanced racing assembly available on the market. 

Each section of the system is manufactured in a special titanium alloy that is both lightweight and resistant to high temperatures, allowing for an overall reduction in the bike's weight. Once installed on the bike, the exhaust dramatically increases the already excellent weight-topower ratio of the Panigale, for breathtaking accelerations and stretches. 

Thanks to its experience in the races has developed the qualities of the motorcycle and exhaust to their maximum levels to create a perfect synergy, specifically for this exhaust, recalibrating the many and fundamental electronic aids: DTC, DWC, DPL and Slide on demand. 

Weight reduction [kg] 6.0. Power at medium rpm [hp] +6% ; Torque at medium rpm [Nm] +6%; Max. Power [hp] +6%; Max. Torque [Nm] +6% .

Dry clutch kit

Just like in MotoGP, where the only thing that matters is utmost performance, the dry clutch is made available for the new Streetfighter V4.

This is an STM EVO-SBK clutch made from billet aluminium with housing and 48-tooth plate pack. The plates are 9 driven and 9 lined with a diameter of 138 mm.When racing on the track there are important benefits in ease of handling.

Specifically, the dry clutch ensures a more effective slipper function, even during the most aggressive downshifts, and greater fluidity during all "off-throttle" stages. In addition, the "mechanical" engine brake level can be customised by choosing a different secondary spring from those available from the catalogue.Other important advantages are the absence of resistance from the engine oil and cleaner oil since the plate wear dust is not conveyed into the lubrication circuit.

The racing character of the dry clutch is an exciting added benefit for the most passionate Ducatistas.

Dry clutch cover

Designed to offer optimum ventilation of the dry clutch during track use, enhancing its characteristic sound. The lightness and strength of the carbon fibre combine with the race-ready look in an accessory that has a uniquely sporty DNA.

Magnesium rims

The unmatched lightweight performance of forged magnesium meets style – a signature 9-spoke design that combines class, high performance and weight saving. This set of rims is approved for single-seat use only.

Adjustable rider footpegs in aluminium

Developed thanks to the experience of Rizoma. Made of high quality anodised aluminium alloy that maintains its original appearance over time. 

Adjustable in six positions, they allow the rider to find the position that best suits their build and riding style. Equipped with fold-away brake and gearchange pedals to minimise the risk of breakage in the event of a slip. 

They use the standard DQS, which can be configured both as a traditional shift and as a reversed/racing shift. An essential accessory for the most demanding riders. 

Racing pair of handgrips

Inspired by the racing world, these handgrips ensure an excellent grip in every riding situation. Built to avoid accidental slipping of the hand and to reduce the vibrations felt.

Carbon tank cover

A splendid detail that embellishes the front of the Streetfighter V4 tank in a way that only carbon fibre can. The finishing and lines of this accessory are perfectly integrated into the racing look of the latest bike made at Borgo Panigale.
