2017 Ducati Monster 1200 Ducati Red, Financing Available! 2017 Ducati Monster 1200 Ducati Red Monster Essence The new Ducati Monster 1200 captures the essence of the original iconic Monster: the real naked sports bike. It evolves with a compact, light and sleek design, a powerful yet smooth engine and a world-class equipment. Its sporty attitude and class-leading performance deliver pure riding fun. Concept Ducati goes back to the origins of the Monster, with a bike which is new in both shape and substance.When the Ducati designers began work on the new Monster 1200, they took inspiration from those who had laid the foundations of the first project in 1993: the concept of the "sport naked bike".The Monster 1200 is the essence of the Monster in its purest form. Volumes, silhouettes, tank and headlights are all faithful to the lines of the bike born in 1993. Design When the Ducati Design Centre began work on the Monster 1200, it set itself the task of creating a streamlined bike which was compact and with a sporty character, to return to the concept of the "sport naked bike". Great attention was obviously paid to the tank, now more "taut" and modern, the design of which was completely revised while maintaining the overall feel desired by Galluzzi in 1993. To highlight this connection with the past even more so, the fastening hanger in anodised aluminium has made a return.The short tail, compact and with its sharp lines, supported by the steel trellis frame keeps the height-adjustable seat on two positions (795 and 820 mm) and supports the passenger footpeg plates which are now separate from the rider's. This new configuration gives the Monster 1200 a sporty line and at the same time improves the ergonomics. Wheelbase and swingarm have been shortened to obtain compact proportions and significant improvements in terms of handling and riding precision. Testastretta 11° The Monster 1200 engine is the Testastretta 11° DS twin-cylinder, 1198 cm3 with 4 valves per cylinder, liquid cooled. Euro 4 type-approved it is the structural element of the suspension set-up with coupling points for the trellis frame.The 1198 Testastretta 11° DS breathes through the Ride-by-Wire Mikuni throttle body with oval cross-section with a diameter of 56 mm with two spark plugs for each head: the double flame front ensure combustion is completed extremely quickly which, together with the secondary air system optimising operation and reducing cyclical dispersion of the combustion without any impact on pollutant emissions, translates into a more regular distribution providing a more pleasurable and exciting riding sensation. Great attention was paid to improving engine response in terms of modulating the engine response times to the actions on the accelerator.

2017 Ducati Monster 1200 R Red, 2017 Ducati Monster 1200 R Red Be seduced Sleek tailpiece lines grab the eyes with their sporting looks. 160 hp delivered smoothly by the R power unit charm the ears with their racing accent. A track-ready chassis and perfect riding ergonomics change attraction to seduction at every effortless change in direction. 180 kg of total control enhanced by the sophisticated elegance of special R componentry. "R" engine All the elements that created the Monster legend are evident at a glance: a powerful "Monster-fly-line", round headlight flanked by the forks, solid and sculptural metal fuel tank, and the authentic "less is more" style concept that gives the perception of being in front of an engine, a chassis, a tank, a saddle; and nothing more. The Designer wanted to communicate the top performance of the Monster 1200 R with a sport, compact and light design to create the image of an individualistic model, almost single-seat. The rider and passenger seats group (still using a single-seat solution) is visually short and narrow delivering an elegant sportiness. The tail and the passenger seat cover show a razor volume characterized by strong and marked surfaces. The side view of the seat is compact, and thin. The rear frame is completely new, with a light structure design. The passenger foot pegs support, are separated and directly fixed to the sub-frame. The high-mounted license-plate holder made in aluminum enhances the view of the huge rear tire 200/55 that, as a result of the rised chassis set-up, is distant from the tail by increasing the feeling of lightness of the rear view. The forged wheels reproduce the same tri-W design as of those of Panigale S / R. Attention for details The new Monster 1200 R visibly communicates sophistication and premiumness. A metal plate with model designation enriches the view of the passenger seat after removing the seat-cover while on the radiator cover in brushed steel is obtained by sandblasting the original «R» graphic. The seat is upholstered with two different materials stitched together with a red stitching bordering the rider's zone. Color range The Monster 1200 R is available in Ducati Red and in the new Thrilling Black, both colour versions are enriched with a sporty longitudinal "R" graphics that marks front mudguard, mini-fairing, tank and passenger seat cover.

It is a Monster, sporty and essential, and it's easy to ride, never intimidating: it is all you need to have undemanding fun. Furthermore, its versatility makes it the perfect gear for your everyday riding experience. The Monster 797 is available in three huge colours: Star White Silk, with red frame and wheels, the classic Ducati Red, with black frame and wheels and smart Dark Stealth with black frame and wheels. Available also in Plus version, equipped with passenger seat cover and wind shield. Concept Ducati presents the new Monster 797, the bike with the essence of the Monster and Ducati values finally within everyone's reach. Sporty, compact, essential but at the same time sophisticated and modern, the Monster 797 is the incarnation of all the Monster values and represents a way into the Ducati world. Everything on the Monster 797 takes us back to the iconic bike of the 1990s, reinterpreted in a modern key: from the tank to the trellis frame, including the twin-cylinder air-cooled engine and the circular headlight. Design With the Monster 797, the Ducati Design Centre has created a sporty and compact bike, with a dynamic, fresh design which encompasses all the Monster values. The tank is Monster in its purest form. Elegant and muscular at the same time, it has a fastening hanger at the front just like the Monster of 1993. The headlight, once again round, is the modern interpretation of what was used on the iconic naked fin right from the start. On the Monster 797, the frame is not just a structural component but it is a real design element and is once gain made as a single piece, from the rake to the tail, including the traditional tube handles for the passenger. The same concept is true of the air cooled Desmodue twin-cylinder engine whose cooling fins take us right back to the first generation Monster. Desmo2 The Monster 797 is fitted with the air cooled 803 cm3 Desmodue twin-cylinder engine. This engine is a nod to the origins of the Monster but it is a modern Euro 4 homologated engine able to deliver 75 hp* at 8,250 rpm and a maximum torque of 69 Nm at 5,750 rpm. Characterised by an 88 mm bore and a 66 mm stroke, it has been designed to offer pure riding enjoyment, like a real Ducati, without ever seeming demanding. *The power values indicated above are measured using a chassis dynamometer. Homologated power data, as quoted in the Bike Registration Document, are measured using an engine dynamometer according to the homologation regulation. The two power values may differ because of the different measurement equipments.

Design It takes just a glance to see all of the elements that contribute to creating the legendary Monster: the muscular, sporty line, the rounded front headlight flanked by the forks, the high number plate, the compact yet imposing metal fuel tank. The unmistakable "minimalist" design that gives you the impression of being in front of an engine, a frame, a tank, a seat, and nothing more. Despite its larger size, which offers unprecedented performance and versatility, the Monster's proportions immediately reveal the heart of a sports bike. The mass is visually concentrated at the front and the engine area looks compact, even with the new water cooling system, into which the radiator and the water supply pipes have been cleverly incorporated. The engine is combined with an impressive side-mounted staggered exhaust system that leaves no room for doubt about the bike's performance.
