DESIGN

As with all Aprilia, a lot of care and attention has been answered in detail in the SXV. Consequently, the SXV boasts a unique style that is still recognizable in full operation in achieving unprecedented performance, because first, although the standard SXV is a genuine competition motorcycle.

But the SXV is not just a pretty face. Your eyes are in possession of an abundance of advanced technologies. A look at the V2 engine, mixed trellis and aluminum frame, powerful exhaust swingarm and twin central with silencer in the rear wing, and you can not escape its magical attraction.

Whatever side you look at it, SXV presents a host 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.

As you would expect from Aprilia, the latest SXV is packed with clever design solutions. Fixed air ducts, for example, allow the fuel tank tilt for easy access to the airbox. And the search for technical perfection has led the design team to fine tune the little details, even on the basis of the contributions of the champions who have raced the SXV.

ENGINE: current developments

The amazing 45.2 engine is, of course, an integral part of SXV technology. Aprilia was the first manufacturer in the world believe in the validity of the V-twin supermoto, the segment with 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. Early stage of design, the 45.2 has evolved to maintain the development of the platform and to provide an unbeatable combination of power and handling SXV.

The 77 ° V angle is the result of extensive testing, not only to train but also to reduce vibration. Therefore, the Aprilia engineers were able to remove the motor shaft balancer.

Despite the 45.2 engine still vibrates far less than any alternative to a cylinder.

The cylinders themselves are integrated in the crankcase and have replaceable wet liners. This unique layout has allowed the engine accessories to be arranged in a way that achieves extremely compact dimensions. The results are amazing: the Aprilia V twin is one of the most compact V twins in the world, and smaller than many singles of similar displacement. All design choices have been taken to obtain maximum power plus an extended useful power band. The sophisticated electronic engine management, developed by Aprilia Racing, contains many innovations for the off-road sector.

The injection system features 38 mm throttle bodies (40 mm in 550) and is managed by a programmable control unit. The ECU will be able to switch between two different assignments at the touch of a switch on the handlebar. This useful innovation offers a maximum power allocation for use in conditions of good grip, and mapping of a second, softer for smoother power delivery under difficult conditions. The system provides valuable assistance for the control and was hailed by both experienced riders (the system has proven fact in the final tournament in the world) and supermotard fans in general. It only takes one click to select exactly the right power for the circumstances.

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.

The simple configuration camshaft with four valves per cylinder, titanium is an ideal compromise between compact size, low weight and high performance.

Thanks to advanced technology, the 45.2 is also extremely quiet and environmentally friendly engine. Technology, after all, should mean reliability and longevity with high performance. 45.2 engine touches new heights in this direction, and allows easy access to parts requiring regular maintenance, such as spark plugs, oil filters and air filter.

Like a lot of effort put into weight loss, and 45.2 engine sets a new record for a V-twin with an electric starter. The extensive use was made of lightweight prestige materials. The central crankcase sections of aluminum-silicon alloy, engine cases external magnesium, titanium valves are, and all gears are exceptionally light.

The starter is new and has a knob on the airbox instead of a successful control. Even the air filter has been improved and is now made from a fungus that comes from that used on machines official Aprilia Racing.

More in detail the unique features of the 45.2 engine:

- The electronic fuel injection with throttle body 38 mm (40 mm on the engine 550).

- Dry-sump lubrication with separate gearbox external tank and the engine oil to avoid contaminating engine oil with particles of clutch friction lining, and for the life of the lubricant.

- Single camshaft four valve heads

- Piece crankshaft

- Cylinders integrated in crankcase with wet liners

- Maximum speed 12 500 rpm (450 motard)

Body: lighter than ever

A machine like the SXV inflexible demands a great chassis. The perimeter frame is a steel tube interference lattice structure with pressed aluminum side rails to form an extremely rigid. The engine itself is part of the chassis, acting as a load bearing element and contributing to overall stiffness.

The swing arm with variable section aluminum alloy is a brilliant example of industrial design. More than just eye-catching design solutions, this revolutionary swingarm offers the highest structural rigidity available in this category of bike. The link rate increase suspension is damped by a Sachs monoshock fully adjustable with piggy back cylinder and two different hydraulic settings high and low speed. Calibration of the rear suspension has been modified to improve stability and control on rough surfaces and a clutch system has been introduced to make the damping action of the shock more progressive, increasing both the tensile and control.

The positive side of 48 mm fork also has a new configuration for greater high speed stability and improved damping off-road use.

Brake System

Advanced technology and high performance of the SXV chassis are shown an excellent braking system. SXV stand FTE calipers and lightweight wave discs (front 320 mm), more powerful braking control even under the toughest conditions.

Rear brake 240 mm disc with single piston caliper for a perfect combination of power and control.

COMPONENTS: READY TO RACE

All parts of the Aprilia SXV is the best quality available.

Among the many prestige components are:

- Digital instruments: ultra-lightweight, compact and designed to provide all the information about the pilot may be needed.

- Handlebar Magura tapered aluminum with any member of the Cross of elasticity and optimal control

- High luminosity LED tail lights

- Aluminum oil filter cover

- New engine start push of a button (rather than block the ignition of age)

- New racing electrical system

SXV VDB Replica

Developed entirely in game racing Aprilia SXV VDB Replica is the pinnacle of competitive Aprilia machines. With no other changes at all, this bike is capable of competing with and manage any competition throughout the world. SXV VDB Replica is the first step in the development machine, Aprilia Supermoto Championship is.

The VDB Replica SXV differs from the standard in a number of technical details that make this already highly competitive machine even faster on the track. Engine 77 ° V-twin, available in 450 and 550 cc versions, is essentially equivalent to the standard power plant, but changes to a number of pieces of basic transmission. Multi-plate wet clutch provides a sophisticated slipper device to make handling more flexible and efficient entry into the corners and box features new ratios plus a brand new electronic control unit connected to the ignition system for rider to avoid using the clutch to move from one sprocket to another, speeding the transfer of offset and less weight within sub-conditions riding.

Like the standard SXV, the new VDB Replica offers two different engine mappings that can be activated even during a race by simply pressing a switch on the handlebar. This unique feature allows you to customize the delivery of engine power to change the state of the track and the wear of the tires.

Frame contains too many improvements. The body is even lighter, thanks to design changes mainly involving the die cast aluminum spars and the rear fork is shorter and lighter than the standard SXV.
