Ducati 749
The Ducati 749 is a 90° V-twin Desmodromic valve actuated engine sport bike built by Ducati Motor Holding between 2003 and 2006. Designed by Pierre Terblanche, the 749 was available as the 749, 749 Dark, 749S, and 749R. It shared many of its parts with the 999 999 or triple nine most often refers to: * 999 (emergency telephone number), a telephone number for the emergency services in several countries * 999 (number), an integer * AD 999, a year * 999 BC, a year Books * ''999'' (anthology) or ''999: T ..., with the exception of a slightly smaller 180/55 profile rear tire, smaller cylinders, and different cylinder heads, giving it a smaller displacement of 748 cc. This smaller engine is higher revving and produces a lower peak horsepower than the larger engine used in the 999. The 749S model, like the 999, incorporates features rarely found on production motorcycles, including adjustable rake (23.5° or 24.5°) and five-position adjustable rearset mounts. A limited n ...

Roller Chain
Roller chain or bush roller chain is the type of chain drive most commonly used for transmission of mechanical power on many kinds of domestic, industrial and agricultural machinery, including conveyors, wire- and tube-drawing machines, printing presses, cars, motorcycles, and bicycles. It consists of a series of short cylindrical rollers held together by side links. It is driven by a toothed wheel called a sprocket. It is a simple, reliable, and efficientAs much as 98% efficient under ideal conditions, according to means of power transmission. Sketches by Leonardo da Vinci in the 16th century show a chain with a roller bearing. In 1800, James Fussell patented a roller chain on development of his balance lock and in 1880 Hans Renold patented a bush roller chain. Construction There are two types of links alternating in the bush roller chain. The first type is inner links, having two inner plates held together by two sleeves or bushings upon which rotate two rollers. I ...

Sport Bikes
Sport pertains to any form of competitive physical activity or game that aims to use, maintain, or improve physical ability and skills while providing enjoyment to participants and, in some cases, entertainment to spectators. Sports can, through casual or organized participation, improve participants' physical health. Hundreds of sports exist, from those between single contestants, through to those with hundreds of simultaneous participants, either in teams or competing as individuals. In certain sports such as racing, many contestants may compete, simultaneously or consecutively, with one winner; in others, the contest (a ''match'') is between two sides, each attempting to exceed the other. Some sports allow a "tie" or "draw", in which there is no single winner; others provide tie-breaking methods to ensure one winner and one loser. A number of contests may be arranged in a tournament producing a champion. Many sports leagues make an annual champion by arranging games in a r ...

Ducati Motorcycles
Ducati Motor Holding S.p.A. () is the motorcycle-manufacturing division of Italian company Ducati, headquartered in Bologna, Italy. The company is directly owned by Italian automotive manufacturer Lamborghini, whose German parent company is Audi, itself owned by the Volkswagen Group. History In 1926 Antonio Cavalieri Ducati and his three sons, Adriano, Marcello, and Bruno, founded ''Società Scientifica Radiobrevetti Ducati'' (SSR Ducati) in Bologna to produce vacuum tubes, condensers and other radio components. In 1935 they had become successful enough to enable construction of a new factory in the Borgo Panigale area of the city. Production was maintained during World War II, despite the Ducati factory being a repeated target of Allied bombing. It was finally destroyed by around 40 Consolidated B-24 Liberators on 12 October 1944 as part of the United States Army Air Forces's Operation Pancake, which involved some 700 aircraft flying from airfields in the Province of Foggia. ...

Rake And Trail
Bicycle and motorcycle geometry is the collection of key measurements (lengths and angles) that define a particular bike configuration. Primary among these are wheelbase, steering axis angle, fork offset, and trail. These parameters have a major influence on how a bike handles. Wheelbase Wheelbase is the ''horizontal'' distance between the centers (or the ground contact points) of the front and rear wheels. Wheelbase is a function of rear frame length, steering axis angle, and fork offset. It is similar to the term wheelbase used for automobiles and trains. Wheelbase has a major influence on the longitudinal stability of a bike, along with the height of the center of mass of the combined bike and rider. Short bikes are much more suitable for performing wheelies and stoppies. Steering axis angle The steering axis angle is called caster angle when measured from vertical axis or head angle when measured from horizontal axis. The steering axis is the axis about which the steer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pierre Terblanche
Pierre Terblanche is a South African motorcycle designer born on 6 November 1956 in Uitenhage, Eastern Cape. He started his career in advertising but felt the need to move into the design world. After moving to Germany and working with Volkswagen design, he worked at Cagiva's research center at San Marino under the direction of Massimo Tamburini. When Cagiva decided to sell Ducati to US-based TPG Capital, L.P., Texas Pacific Group, Pierre Terblanche chose to follow Ducati. In December 2007, he left Ducati to pursue other interests, believing that he should be a designer and not a manager. Subsequently, Pierre Terblanche worked for Piaggio on the Moto Guzzi and other brands, along with former colleague Miguel Angel Galluzzi, who designed the Ducati Monster. Terblanche left Piaggio to join Norton Motorcycle Company in January 2011. In early 2013, it was announced that Terblanche had joined Confederate Motors in Alabama, United States, as head of product development, and i ...

Desmodromic Valve
:''In general mechanical terms, the word ''desmodromic'' is used to refer to mechanisms that have different controls for their actuation in different directions.'' A desmodromic valve is a reciprocating engine poppet valve that is positively closed by a cam and leverage system, rather than by a more conventional spring. The valves in a typical four-stroke engine allow the air/fuel mixture into the cylinder at the beginning of the cycle and exhaust spent gases at the end of the cycle. In a conventional four-stroke engine, valves are opened by a cam and closed by return spring. An engine using desmodromic valves has two cams and two actuators, each for positive opening and closing without a return spring. Etymology The word comes from the Greek words ''desmos'' (, translated as "bond" or "knot") and ''dromos'' (, "track" or "way"). This denotes the major characteristic of the valves being continuously "bound" to the camshaft. Idea The common valve spring system is satisfactory f ...

Ducati 999
The Ducati 999 is a sport bike made by Ducati from 2003 to 2006. It superseded the Massimo Tamburini designed Ducati 916, Ducati 996 and Ducati 998 range of superbikes. This motorcycle enjoyed great success in World Superbike, and was raced in the series through the 2007 season, despite no longer being produced, pending rules changes by the series' governing body, FIM, to allow competition of the new Ducati 1098. The 999 was designed by Pierre Terblanche, amid much controversy over its styling. It is known as a high performance, race oriented motorcycle. With its traditional Ducati L Twin Desmodromic Valve actuated engine layout, it has a linear power delivery, with high power and torque figures available even at low RPM. Additionally, with its high spec suspension and trellis chassis, it is one of the finest handling motorcycles for its time. Subsequently, more powerful 999S and 999R versions were introduced, both capable of 0-62 mph (0-100 km/h) in under three sec ...

Clutch
A clutch is a mechanical device that engages and disengages power transmission, especially from a drive shaft to a driven shaft. In the simplest application, clutches connect and disconnect two rotating shafts (drive shafts or line shafts). In these devices, one shaft is typically attached to an engine or other power unit (the driving member), while the other shaft (the driven member) provides output power for work. Typically the motions involved are rotary, but linear clutches also exist. In a motor vehicle, the clutch acts as a mechanical linkage between the engine and transmission, and briefly disconnects, or separates the engine from the transmission system. This disconnects the drive wheels whenever the clutch pedal is depressed, allowing the driver to smoothly change gears. In a torque-controlled drill, for instance, one shaft is driven by a motor, and the other drives a drill chuck. The clutch connects the two shafts so they may be locked together and spin at the ...

Manual Transmission
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canada, the United Kingdom, and the United States), or stick shift (in the United States), is a multi-speed motor vehicle transmission (mechanics), transmission system, where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually a foot pedal for cars or a hand lever for motorcycles). Early automobiles used ''sliding-mesh'' manual transmissions with up to three forward gear ratios. Since the 1950s, ''constant-mesh'' manual transmissions have become increasingly commonplace and the number of forward ratios has increased to 5-speed and 6-speed manual transmissions for current vehicles. The alternative to a manual transmission is an automatic transmission; common types of automatic transmissions are the Automatic transmission#Hydraulic automatic transmissions, hydraulic automatic transmission (AT), and the continuously variable transmissio ...
