Engine

Back

Euro 5 engine

With the arrival of 2021, all the bikes in the Ducati Streetfighter V4 range become compliant with the Euro 5 anti-pollution regulations, keeping the maximum power and torque values unchanged, but repositioned at different speeds. 

The Streetfighter V4 Euro 5 delivers 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

The silencer, unchanged from an aesthetic point of view, uses oversized catalysts (+10 mm in length) and a new technology of insertion of noble metals, essential to maximize the ability to convert polluting gases. 

Compared with the Euro 4 models, the rear bank manifolds have been 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 rear heat shield integrated in the body of the motorcycle. 

Also in favor of reducing emissions, the introduction of 4 lambda sensors, one for each cylinder, which allow a more refined control of the quantity of fuel injected.

MotoGP-derived engine

The Desmosedici Stradale was designed around the heart of the MotoGP V4 engine – its cylinder heads.

The fluid dynamics concept of the Desmosedici Stradale is based on the dimensions and geometry used in the Desmosedici GP bike, as is the engine layout: 90° V4 banked rearward 42°. This solution makes the engine extremely compact, allowing the centring of the masses and better integration into the bike.

Racing architecture: road and track

The 81 mm bore is the same as that used on the Desmosedici GP, the maximum size allowed by MotoGP regulations, and is the largest in the Supersport 4-cylinder segment. The 53.5 mm stroke is longer than the GP engine, to provide increased torque when used on the road, and reduce maximum engine rotation speed. The use of the same bore as the Desmosedici GP engine means that all the fluid dynamics, which in fact make up the heart of the engine, 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.

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.

Let’s get down to details

There are a multitude of engineering and technological aspects conceived for this champion road bike. A balance of distinctive lines, brutal output, state-of-the-art technology and components have been combined in this “Fight Formula” of the Streetfighter V4.
