Ducati Desmosedici

Ducati Desmosedici is the name of the series of 4-Stroke V4 prototype developed by Moto Ducati to compete in the MotoGP World Championship. GPX is the version of the bike, where x is the years the bike race (ie the Desmosedici GP8 raced in 2008). Ducati has also made a Desmosedici racing replica called Desmosedici RR • Background Ducati abandoned the Grand Prix racing scene at the beginning of 1970. For many years the 500 class was essentially a class for two-stroke bikes, an engineering technology that was far from the road four-stroke machines being sold by Ducati. Technical standards changed in 2002, giving priority to four-stroke machine and turning the 500 class of World Road Racing Championship in MotoGP. This convinced Ducati to make a long-awaited return to the track in the new MotoGP class. Ducati story is based on the classic L-twin engines, using desmodromic valve technology. Initially, Ducati into account the possibility of creating a MotoGP 'super-twin', taking advantage of the MotoGP regulations that give twin-cylinder machines a considerable weight reduction over four, five or six-cylinder bikes. However, the analysis indicated that a twin-cylinder engine was not able to produce the necessary quantity of energy (more than 230 hp), without unduly increasing the number of laps. A Twin would have had to rev at over 17,000 rpm, but this would require a very short race and a great forum, as a possible result of combustion that produce problems. The basic design of the Desmosedici engine is therefore two classic Ducati L-Twins side by side, making a double-double with 2 L Stroking cylinders at the same time (also called Twin Pulse). With four valves per cylinder, the total number of sixteen valves is - Desmosedici desmodromic means of distribution with sixteen valves reduced in Italian Design had begun in 2001 with Alan Jenkins, the bike was inaugurated in 2002 Italian GP at Mugello, for use in the following seasons of the MotoGP World Championship. Vittoriano Guareschi, the Ducati Corse test pilot, followed every phase of the Desmosedici in the development process from early testing to track debut and the evolution of the project. In 2007, Ducati pilot Casey Stoner, riding a Desmosedici, Ducati awarded the first MotoGP World Championship title. GP3 While still fully committed to Superbike racing, Ducati Marlboro Team of Loris Capirossi and Troy Bayliss could compete in all rounds of the 2003 MotoGP championship. The Desmosedici GP3 quickly scored a series of results with Loris Capirossi, who stepped on the podium in the opening round of the championship in Japan and won the GP of Catalunya in Barcelona. Riders Capirossi finished fourth in the championship final ranking and Bayliss sixth, while Ducati finished second overall in the Manufacturers' classification GP4 In 2004 the Desmosedici GP4, again in the hands of Capirossi and Bayliss, underwent a series of important changes. A large part of the season went by before the bike became competitive, but concluded the season with both drivers on the podium. A 989 cc, the GP4 the maximum recording speed of 347.4 km / h (215.9 mph) was set by Loris Capirossi on a test Irta in Catalonia, Spain. GP5 Loris Capirossi leads the GP5 (top) and GP6 (bottom). The GP5 version lined up for Ducati the third season in MotoGP, with Bayliss replaced by Spanish driver Carlos Checa. Thanks to a collaboration agreement with Bridgestone, Ducati could finally contribute to the development of new tires and by the end of the season Desmosedici become a competitive car. Bridgestone found that hard tires fit the bike over to create soft rubber grip - put simply, allowing it to turn back the wheel has better control. Capirossi took two victories in the Japanese Grand Prix at Motegi and in the GP of Malaysia at Sepang, while Checa still scored a podium finish GP6 Launched at the Italian ski resort of Madonna di Campiglio, the GP6 is lighter and more powerful version of GP5. Involve better aerodynamics and better position the fuel tank, more importantly, even if more powerful engine delivery was cleared to make the bike more ridable. This has made the bike slower on top speed, but the fastest around and out of corners [1]. The new pilot Capirossi was Spanish rider Sete Gibernau. After encouraging winter tests, the Desmosedici GP6 took his first victory of 2006 in opening GP at Jerez de la Frontera, Spain, followed by a podium in Qatar. Capirossi led the league for a short time, but the departure of Gran Premio de Catalunya in Barcelona, Gibernau's bike collided with Capirossi after Gibernau braked too late and its tablet brake lever when impacting ferther on the back of the Capirossi Cycling. Both drivers finished and wounded in hospital, with Gibernau with a broken collar bone, and both lost the Dutch Grand Prix at Assen. Capirossi returned to the British Grand Prix, while Gibernau was replaced by German Alex Hofmann for the Dutch Grand Prix, the Grand Prix of Great Britain and the Czech Republic Grand Prix after undergoing additional surgery. With Gibernau still out for the final stage of the season at Valencia, Ducati Bayliss said, who was recently crowned World Superbike champion. The race was won by Bayliss, his first MotoGP victory, with Capirossi in second place for the first Ducati 1-2 final. GP7 For 2007, MotoGP rules have been amended to cap engines to a maximum displacement of 800 cc. In response, he built the Ducati GP7. Its specifications are: 800 cc bike, double L-Twin motor (4 Cylinders Twin Pulse), about 168 kW (225 bhp) at 19'000 rpm and 330 km / h top speed (Confirmed 337 2 km / h (209.6 mph) [2]. Ducati began his project for the construction of a 800 cc MotoGP bike very early, and according to the Ducati racing chief Filippo Preziosi, from August 2006 Ducati had already built 20 800 cc engines with different specifications [3]. In addition, an early version of the bike path was tested for the first time during the beginning of May 2006 [4]. Post test with the bike started to Brno Track, where Loris Capirossi won the day before riding the GP6, Aug. 21. Capirossi on lap times the prototype GP7 were only 1.4 seconds on his track record time set to 990 cc GP6. Further evidence of GP7 to Motegi, Japan, revealed that the 800 cc car could run faster laps higher displacement 990 cc bikes, and held almost a second advantage over the next fastest 800 cc bike, a Honda ridden by Dani Pedrosa. It was noted in MOTOSPRINT [citation needed] that, as of Le Mans Grand Prix GP7 had a 20 hp (15 kW) advantage over a Honda and Yamaha MotoGP bike. This advantage of a power that has made a significant speed advantage through the first part of the season. The bike was said to have aerodynamic settings that could be changed to increase the maximum speed, if necessary, [citation needed]. MotoGP 800 cc era officially began with the first race of the 2007 MotoGP season at Losail International Circuit in Qatar. Casey Stoner won the race on the new GP7. The bike had a clear top speed advantage over the rest of the network, because of its higher output motor. A new track record was set on the GP7. Second place competitor and former five-time world champion, Yamaha's Valentino Rossi, testified that "unfortunately, there was too much difference between (our) bicycle in a straight line" and "Our Yamaha will never go as fast on a straight as the Ducati. " These words are proved true, as the GP7 enjoyed a top speed advantage throughout the season, even if the other manufacturers (Yamaha, Honda, Kawasaki and Suzuki) closed the gap significantly by the end of 'year. Stoner and his Bridgestone-Ducati shodě shown to be superior in combination MotoGP and won the world championship at Motegi, Japan, on 23 September 2007, four races before the end of the season. At the end of the season, the Ducati chief engineer Alan Jenkins was awarded the Sir Jackie Stewart Award for brilliance throughout the season [5]. GP8 The evolutionary update GP7 design [6], Ducati's entry for 2008 MotoGP World Championship [7] was first tested in February 2007. In order to avoid chatter, which has been found in some occasions with the GP7, the rigidity of the chassis of the GP8 has been altered, although details are not significant changes disclosed. [8] [9] In addition, in an attempt to reduce the effect described as "pumping", some changes to the bike geometry of the suspension was made. [10] [11] Like its predecessor with the GP8 contains a 4-cylinder 800cc engine with desmodromic maneuver its 16 valves. The engine has improved mid-range and the answer top-end power than the GP7. In 2007 Ducati tested a fuel-saving special clutch disengaged agreement that the friction braking and reduced fuel consumption, however, the agreement was not accepted because various GP8 advanced lubricants and fuels used with the GP8 you feel provide comparable fuel savings, while decreasing friction inside the engine and increasing the maximum power [12]. In race trim the motion recorded an official top speed of 343.2 km / h (213.3 mph) in 2008 Chinese Grand Prix motorcycle. [13] However, in a video of the same race, Casey Stoner is seen driving the bike at speeds of 347 km / h (216 mph) [14]. GP9 I am testing on the track since May 2008 and his Ducati entry for 2009 MotoGP World Championship. [15] On 9 June 2008, Ducati Desmosedici rolled publicly GP9 for tests at the Circuit de Catalunya [16]. A distinctive feature of the GP9 is his frame in carbon fiber, representing a departure from traditional Ducati trellis steel frame. [17] Although carbon fiber chassis were found in mid-1980, currently no other MotoGP Racing Team uses them [18]. ________________________________________ Ducati Desmosedici GP8 (2008) Specifications Engine Engine type: Liquid-cooled, 90 degrees, V4 4-stroke with 16 valves, DOHC Desmodromic Displacement: 799 cc Switching: Magneti Marelli Fuel system: Fuel injection Lubrication system: Racing Shell V-Power Date of registration: Maximum power: about (170 kW) 230 hp Top speed: 350 km / h (in excess of 215 mp / h) [19] Transmission Type: 6-speed cassette-type gearbox, with alternative gear ratios available Primary drive: Gear Clutch dry multi-plate slipper clutch Final: Chain The chassis and running gear Type of frame: tubular steel trellis-style chassis, pressed aluminum swing-arm Front suspension: Öhlins upside-down front forks 42 mm Rear Suspension: Öhlins rear shock, adjustable pre-load, compression and rebound damping Front / rear wheels: 16.5 "front and rear Front / rear tires: Bridgestone Front brake: Brembo, 320 mm carbon front two discs with four piston callipers Rear brakes: Brembo, unique stainless steel rear disc with two piston callipers Weight: 148 kg or 326 pounds Fuel capacity: 21 liters or 5.5 gallons Desmosedici RR (Racing Replica) In 2004, Ducati has announced that it would produce a low volume of reply tailor the Desmosedici, available from 2006.
