DESIGN: DETAILS COUNT
As with all Aprilia, a lot of care and attention has been answered in detail on the RXV.
Consequently, the RXV boasts a unique style that can be recognized, however, fully functional in achieving this unprecedented performance that requires a real racing motorcycle.
Essential, essential lines convey a feeling of lightness and build quality. The designers were RXV eager to incorporate the elements that characterize all Aprilia, and launched a new type of dirt bike. You can not fail to appreciate technology as a V-twin engine, mixed steel trellis frame, and sculptured swingarm. The tail and rear side panels are completely different to the traditional concept of off-road design. Any way you look, RXV provides a wealth of stunning technical solutions for all enhanced by original racing colors to express the aggressive nature of the Mean Machine was born in the race.
Every aspect of the bike features intelligent design solutions. Fixed air ducts, for example, allow the tank to tilt for easy access to the airbox.
About RXV is dedicated to winning races. The quest for technical perfection has led the design team to further enhance the most insignificant detail based on the contributions of the champions of the time many of those who carried out the RXV.
ENGINE: continuous development
The amazing 45.2 engine is, of course, a key technology RXV. Aprilia was the first manufacturer in the world believe in the validity of architecture of the V-Twin market segment, in which all other Marques still firmly attached to single cylinder engines. High-tech design Aprilia V-twin engine has already proven to be 100% reliable competition. Even homologation for road use and the technology did not compromise the performance of this exceptional engine, which is made entirely from Aprilia.
From the earliest stages of design, the 45.2 has evolved with the development of the chassis and give the RXV an unbeatable combination of power and handling.
The 77 ° V-angle is the result of extensive testing, aimed not only to increase the power, but also to reduce vibration. Therefore Aprilia engineers have been able to eliminate engine balancer shafts.
Despite this, the 45.2 engine still vibrates far less than any single cylinder alternative.
The cylinders themselves are integrated in the crankcase and have replaceable wet liners. This unique design allowed the engine to willing helpers so that achieves extremely compact dimensions. The results are amazing: the Aprilia V twin is one of the twins in more compact and smaller than many singles of similar displacement in the world.
All design decisions have been made to maximize a power strip ridability extended to off-road driving.
The sophisticated electronic engine management, developed by Aprilia Racing, incorporates numerous innovations for the off-road industry.
Injection with 38 mm throttle bodies (40 550) and administered by a programmable ECU. ECU can switch between two different descriptions of a button on the handlebar.
This is an extremely useful innovation offers a complete map of power for use in conditions of good grip and power output of a second, softer smooth mapping in difficult conditions. The system offers a highly skilled support and guidance is welcome as well as experienced riders (the system was tested at the end of the World Championship) and off-road enthusiasts in general. All it takes is a quick select just the right conditions of supply.
The new ECU and the throttle valves of the stepper motor is much easier from all conditions and deliver smooth power and controllable as well.
Control unit has allowed the reduction of crankshaft Aprilia to develop an extremely compact and lightweight. The engine is more sensitive to changes in the throttle, therefore, and the bicycle as a whole is faster and more manageable by reducing the gyroscopic effect of the crankshaft.
MY '09 in weight flywheel is increased to improve power delivery and achieve a smoother ride.
The simple configuration camshaft with four valves per cylinder, titanium is an ideal compromise between compact size, low weight and high performance.
Thank you to its advanced technology, the 45.2 is also a very quiet operation and environmentally friendly engine.
Technology, after all, should mean reliability and longevity and high performance. The 45.2 engine touches new heights in this sense, and allows easy access to parts that require regular maintenance such as spark plugs, oil filter and air filter.
Effort to lose weight and also the 45.2 engine sets a new record with a V-Twin electric start. Rich has used the prestige lightweight materials. The central crankcase sections are in an aluminum-silicon alloy, a magnesium crankcase external, titanium valves, and all engines are exceptionally lightweight.
More in detail the unique features of the 45.2 engine:
- Electronic fuel injection system for the 38 mm throttle bodies (40 mm 550) with stepper motors and a new unit, which provides better performance.
- Dry sump lubrication with separate external tank gearbox and engine oil to avoid contaminating engine oil with particles of clutch friction lining, and for extended lubricant life.
- Single overhead cam head with four valve heads
- Part of the crankshaft
- Cylinders integrated in crankcase with wet liners
- Maximum motor speed 12 000 rpm (450 version)

Body: lighter than ever
An uncompromising machine like RXV demands a great chassis.
The perimeter frame was developed in collaboration with the engine, with the result that the RXV 2011 has lost 2 kg in weight. The lattice structure of tubular steel beams is equipped with interference from forged aluminum to form an extremely rigid.
The same engine is an integral part of the platform, which manages the load bearing element and contributing to overall rigidity.
The aluminum alloy swingarm section variable has become even lighter to reduce stiffness and improve traction.
The suspension link rate of increase is damped by a fully adjustable Sachs monoshock with piggy back cylinder and two different configurations for hydraulic high and low speeds.
The calibration of the rear suspension has been modified to improve stability and control over rough surfaces.
The 45 mm inverted fork also has a new configuration for greater high speed stability and improved damping on rocky ground, and can be adjusted to meet the more advanced users.
BRAKING SYSTEM
Advanced technology and high performance platform RXV shows excellent braking system. RXV stand out with a Nissin lightweight wave discs (270mm front), more powerful braking control even under the toughest conditions.
Rear brake 240 mm disc with single piston caliper (lighter than the previous model), and the perfect combination of power and control.
COMPONENTS: READY TO RACE
All parts of the Aprilia RXV best quality available.
Prestige different components are:
- Digital instruments: ultra-lightweight, compact and designed to provide all the information about the pilot could need.Magura tapered aluminum handles with no cross member for optimal elasticity and control
- High luminosity LED tail light
- Aluminum oil filter cover

- Racing air filter sponge
Major improvements
- New aluminum swingarm with cast body and hydroformed members. The new swingarm is significantly lighter and more flexible, giving clear advantages over traction and better stability on uneven terrain (grooves / ridges).
- Lighter and more compact rear brake caliper.
- New exhaust system homologated side FIM regulations.
Fuel system with stepper motor control of the throttle body and new ECU -. This development makes it easier to start in all conditions and reduces weight significantly too. Power delivery is smooth and easy to control.
- Simplified, lighter rear frame for a low seat and comfortable seat passengers "all sizes".
- Lower seat height (5 mm).
