The new muscular bicycle of 168 horsepower of Ducati of 168 horsepower is supposed to call on the sports cyclists who were tired of the runner race position, but who still want sophisticated and powerful driving.
It is according to the old friend Jason Chinnock, who is the CEO of Ducati North America. Chinnock is not only the CEO; He also put his kilometers on the folded bikes which strengthen Ducati’s reputation for performance.
The four -cylinder engine of 1,158 cm3 of the Xdiaveal V4 is the centerpiece of the bicycle, both visually and technically. He even wins a place in the full name of the model: XDiavel V4. The first generation Diavel had a similar style ready for the mouth of a mouth with a low seat and a rated fork which encourages the front wheel, but the holder is what makes this next level Ducati (do not hesitate to put your own words).
The original Diavel was propelled by one of the Ducati V signature engines with the actuation of the traditional idiosyncratic desmodromic valve of the company. In a desmo engine, camshafts open and close the valves rather than having conventional valve springs which provide the closing action.
For the XDiavel V4, Ducati has gone to a V4 engine used previously by its double sport multi -based model. The speed and power of the Particular V4 engine of the Multistrada family have earned the brand a wide strip of faithful fans, which means that these bikes appear in surprising places. For example, in the 2017 Dax Shepard taking ChipsThe writer / director / actor took the opportunity to present Ducatis before and in the center, although there is no realistic reason for the police to drive Italian motorcycles off -road.
The V4 engine provides interesting features to the XDiavel. To start, it uses regular spring valves rather than desmodromic actuation. But get this; Ducati turns the V4 back! Normally, motorcycle engines run in the direction of travel, but Ducati adds a set of additional gears that allows the rear derivation V4 propels the xdiavev forward.
This has the advantage of using the gyroscopic effect of the engine to cancel the gyroscopic effect of the rotation wheels. The gyroscopic effect stabilizes the bicycle at speed, but for a heavy bike with a long wheelbase due to the aforementioned rated fork, it can make the bike weighing when leaning in the curves. Continue the XDIAVEV V4 through the winding mountain roads between Denver and Estes Park, Colorado, the benefit of this configuration was obvious, because the bike did not look like a stretched 500 + -LB. Cruiser while cutting the curves.
Another interesting technical aspect of the design of the V4 is the rate of shooting of the cylinder. Typical four -cylinder in -line engines draw at equal intervals. This gives Japanese sports bikes their characteristic high RPM cry. As a traditional provider of V -shaped machines with their exhaust note, Ducati wanted a more distinctive sound for his V4.
Four -time four -cylinder engines require 720 degrees (two rotations) to complete their shooting cycle for four -cylinders. In an online engine, this means that cylinders regularly draw 180 degrees.
In what Ducati Terme “Twin Pulse”, the V4 closes its combustion events, the second cylinder pulling only 90 degrees after the first. The engine briefly takes place until the third cylinder after 200 degrees followed 90 degrees later by the fourth cylinder. This leaves almost a complete rotation (340 degrees) of silence before the cycle starts again. This gives a syncopated sound, with two quick explosions followed by another pair of closely spaced combustion events, then nothing.
The result is an exhaust note with the texture to ensure the rider that he is committed to a correctly visceral experience. The Xdiaveal V4 also has a deactivation of the cylinders, which closes the rear shore of the cylinders in slow motion and the accelerator. Unlike the V4 automobile, which drone in V4 mode, the XDIAVEV engine sounds like a V-Twin due to the spacing of remaining combustion events.
The deactivation of cylinders offers a modest advantage of fuel economy, but perhaps more important, it reduces the heat of the waste generated while wading in slow traffic, offering the rider better comfort.
An additional advantage of cluster power race events is engine tractability. It was the theory behind the MotoGP “Big-Bang” motors, which were used because the fraction of a second fraction in power delivery proved to be sufficient to give the runners a better capacity to manage Wheelspin while accelerating.
This must be a good idea, but it is not necessary on the XDiavel V4 due to the electronic aid of cyclists, who are even better than MotoGP runners in the control of Wheelspin. In addition to providing a traction control, the computer allows the rider to select from four driving modes (sport, tour, urban and rain), each used one of the three modes of engine power (high, medium and low).
In high power mode, the XDiavel V4 provides its 168 hp with a quick response to the Twist handle accelerator. In the middle, you always get full power, but the engine responds more judiciously to the Yanks of the rider on the twist handle. Finally, the low power mode reduces the peak output to 115 hp and simultaneously uses the tainted butterfly card. The low setting of 115 hp is still a lot for a motorcycle, but climbing on a bicycle, another rider that remains in rain mode, with its low level of corresponding engine power gave me an instant contrast with the high power setting which made the XDiaveal slow.
There is also an interruption of light offset ignition intended to let the runners collapse without restarting the accelerator. But that’s about the way you go up with other motorcycles, and I did not discern that Xdiaveal’s reverse was more fluid than for other bikes without this functionality.
The Ducati interface to allow the cyclist to adjust these parameters during the driving is well designed. By pressing a button and twisting a dial on the left handlebars provides quick and easy access to the various settings.
XDiaveal rider’s controls all have a progressive response adapted to riders. Switzers and the response to the brake are all tense, but provide enough movement to allow the pilot to feel that the actions are intentional. This contrasts with the BMW controls, which are more based on pressure rather than on movement, which makes it more difficult to ensure that a button is pressed and more difficult to modulate the brakes for a gentle deceleration.
With its delivery of smooth torque, its friendly clutch and its linear brake response, the XDIAVEV offers an impressive ease of use to accompany its high performance and visceral engine character.
Sinsiring through the mountain passes between Denver and Estes Park, Diave has shown that even an electric cruiser with long stacking can dance. The rear rotation engine surely contributes to the bicycle agility, but the 50 mm inverted fork and the Sachs rear shock absorber have 1.4 inches of additional travel.
My day in the saddle also benefited from seat improvements, which include 2.1 inches of additional foam under the buttocks of the rider. The passenger seat has a 50% more area than before, making it a more reasonable place to sit.
Because Ducati’s planners know that cruising bikes are popular in America, they have delivered the XDiaveal with footballs and commands as you could find on a Harley-Davidson. The handlebars extend accordingly to the flared position of the pilot.
But recognizing the potential of Xdiaveve and its call for non -traditional cruiser runners, Ducati offers an optional location that places the rider’s feet in a more normal position under them. Cycling in this configuration is a transformer and should help offer the experience of sports bicycle refugees.
This position slightly leans the rider forward, in the wind, so you feel less like a sail and more like a rider. But the result is that the handlebars are now too close to the rider. Fortunately, Ducati has already realized that and prepares an optional and more flat and further handlebar for cyclists who choose the bottom of the bottom of the middle.
This is how the company can attract these former sports bicycle runners that Chinnock targets. They will be delighted if they try the Xdiaveal V4, and their backs will probably thank them too.
