Aprilia RXV 550
Evolution in the name of competitiveness: it is the mission of the year model 2009 of the RXV 4.5/5.5 of Aprilia. A gained experience results of packing of Aprilia the excellent ones in the championship of the world of Enduro led to the originators and engineers d' Aprilia transferring much more technology of race in this astonishing motor bike from production.

A gained experience results of packing of Aprilia the excellent ones in the championship of the world of Enduro led to the originators and engineers d' Aprilia transferring much more technology of race in this astonishing motor bike from production.
Everyone implied of the RXV worked hard and in the close cooperation to present a certain number of important improvements compared with the motor bike of last year, preparing model of this year much more �race�, and to improve able to provide whole satisfaction to the riders of amateur and demanding professionals.
DESIGN: COUNT DETAILS
As with all the motor bikes of Aprilia, an enormous amount of care and the attention were lavished on same more the small details on the RXV.
Consequently the RXV asserts single, indubitable naming that is nevertheless entirely - functional by carrying out the kind of execution incomparable that a genuine motor bike of competition requires.
The essential and decisive lines give a feeling of lightness and establish quality. The originators Of the RXV were eager to incorporate the devices which distinguish all Aprilias, and launched a new whole type of cross-country motor bike. Each one appreciates technology like the twin engine of V, the reinforcement out of steel mixed of lattice and the swingarm sculpted. The panels of tail and back are completely different by naming traditional cross-country designs. Any manner look at it to you, the present of RXV a host centre to astound the technical solutions, very increased by original packing colours to express the aggressive nature of this machine of means of born-with-race.
Each aspect of the bicycle comprises the intelligent solutions of design. The fixed ventilation shafts, for example, make it possible the fuel tank to upwards incline for easy access in the box of air filter.
All about the RXV is devoted to the races of profit. Research for the technical perfection undertook the team design to improve even more the small details on the basis of the entry of the champions multi of times which packed the RXV.
ENGINE: CONTINUOUS EVOLUTION
Engine 45.2 narcotic is, naturally, the showpiece of technology of RXV. Aprilia was the first manufacturer in the world to be believed in validity of twin architecture of V in a market segment in which all other Marks cling always rigidly to the simple engines of cylinder. The design of point of twin of the V of Aprilia already proved to be 100% reliable in competition. Even the homologation for the use of road did not compromise the technology and the execution of this exceptional engine, which is produced entirely by Aprilia. Since the parts of the process of design, the 45.2 evolved/moved to follow the development of frame and to give to the RXV an unbeatable mixture of power and handling.
The angle of 77� V is the extended test result, concerned not only the power of amplification but also to reduce the vibration. Consequently engineers d' Aprilia could eliminate from the trees tensioner of engine. In spite of this engine 45.2 always vibrates far less than any simple alternative from cylinder.
The cylinders themselves are integrated in the casing of crankshaft and have the replaceable wet coatings. This single provision made it possible the auxiliaries of engine to be arranged in a way in which carries out extremely compact dimensions. The results are astonishing: the twin of Aprilia V is one of the most compact twins in the world, and smaller in the face than much chooses similar displacement.
All the choices of design were order sunken to obtain the maximum ridability and a prolonged band of power for cross-country horsemanship.
The sophisticated electronic management system of engine, developed by Aprilia Racing, incorporates many innovations for the cross-country segment.
The characteristics of the system of injection the bodies of power control of 38 millimetres (40 millimetres out of the 550) and are controlled by a case of programmable order. New the bodies of power control of ECU and engine step by step make begin of lower part much easier all the conditions, and provide the smoothing tool and the more controllable power too.
Reduced unit displacement made it possible Aprilia to develop an extremely compact and light crankshaft. The engine is more sensitive to the variations of the opening of power control consequently, and the bicycle as a whole is grace faster and more maneuverable with the reduced gyroscopic effect of the crankshaft.
In the MY '09 the wheel increased in the weight to improve the supply of current and to produce a softer turn.
The simple air configuration of cam with four titanic valves per cylinder head represents an ideal compromise between the performance of size, light and high compact.
Thanks to its state-of-the-art technology, the 45.2 is also an extremely quiet operation and an ecological engine. Technology, after all, should mean reliability and longevity as well as high efficiency. 45.2 sizes of contacts of engine news in this direction, and the extremely easy laisux of access at piece-rates requiring regular maintenance like the spark plugs, the oil filter and the air filter.
Just as much of efforts were deployed in the reduction of weight, and engine 45.2 places a new record for a twin of V with an electric starter. The abundant use was made materials of light weight of prestige. The centre sections of casing of crankshaft are out of aluminium-silicon alloy; the external motor casings are out of magnesium; the valves are out of titanium; and all speeds are exceptionally light in the weight.
A � it more attentive with the single characteristics of engine 45.2:
The electronic system of fuel injection with the bodies of power control of 38 millimetres (40 millimetres out of the 550), achieve engines step by step and a new ECU which still gives a better execution.
Dry lubrication of sump with the separate external reservoirs so that the gear box and the engine oil avoid soiling the engine oil with particles of the lining of friction of clutch, and during the prolonged lubricant life.
Simple air cam with four valve heads
Crankshaft of only one part
The cylinders integrated in the casing of crankshaft with the wet coatings
Word rate maximum 12.000 t/mn on version 450
FRAME: LIGHTER THAT NEVER
An intransigent machine as the RXV requires a large frame.
The reinforcement of perimeter was developed at the same time as the engine, with the result that the 2009 RXV lost 2 kilogrammes in the weight. The tubular steel structure of lattice is interference adapted to the side aluminium members forged to form an extremely rigid entirety.
