Unparalleled efficacy and riding pleasure.
This is the most complete version, equipped as standard with a steering damper
and the APRC second generation vehicle dynamic control suite.
APRC is based on an automotive inertia sensor platform, with two gyrometers and
two accelerometers allowing the engine ECU to determine the dynamic state of the
motorcycle and control engine torque accordingly to help the rider exploit the
full performance potential of the bike.
The APRC suite equipping the Tuono V4 R includes:
- ATC (Aprilia Traction Control) with eight different settings for controlling
sliding when powering out of curves in relation to bank angle and throttle
aperture. The system has been tweaked to make the more conservative settings
even more suitable for road use, while leaving the racing spirit of the less
restrictive levels intact;
- AWC (Aprilia Wheelie Control) which helps the rider maintain control in
extreme wheelie conditions by gradually bringing the front wheel back to the
ground, has been appropriately adapted for the different weight distribution of
the Tuono V4;
- QS (Aprilia Quick Shift), which allows instantaneous upshifts without closing
the throttle or using the clutch. Completing the suite of four functions is the
most exhilarating of all: ALC (Aprilia Launch Control).
- Simultaneously pressing both buttons on the joystick on the left hand
handlebar arms the system, as confirmed by the specific message on the display.
From this moment on, all 167,3 horsepower of the beast from Noale are ready to
slingshot the Tuono V4 R like a missile as soon as the rider releases the
clutch, unleashing the astonishing power onto the tarmac through every available
square millimetre of the 190/55 rear tyre. And tyre size does not matter to
APRC, as with its Calibrating function, it is the only system of its kind on the
market capable of self-adapting to tyre size and drive ratio.
Tuono V4 R APRC is a bike with two personalities,
with two distinct display modes - Road and Race - to cater for even the most
exacting rider.
A superbike with high handlebars.
After creating the best superbike of the new millennium, Aprilia revolutionises
the supersports naked segment with its astonishing Tuono V4 R. A bike that goes
beyond the wildest dreams of even the most hardcore enthusiasts - the rider who,
given the chance, would use a race bike just to go for a coffee.
For riders like these and for those with power in their veins, Aprilia has
created a motorcycle with the indomitable spirit of the RSV4 in a feline body
that is in its element when accelerating and braking with unimaginable violence,
that eats up curves of any radius and swallows straights whole.
The performance and features of a superbike, the agility of a naked and the
legacy of an innovative concept born in 2002 with the Tuono 1000 R - a bike that
earned both critical acclaim and sales success - but with an extraordinary ace
up its sleeve: the performance of a 65° V4 engine and the most advanced
electronics available in a motorcycle today.
Like the original Tuono, the V4 R is also immediately recognisable with its
triple headlight fixed top fairing, the distinguishing trait of a bike which,
like its twin cylinder predecessor, has the body and soul of its WSBK
homologated sibling, but now - as well as having two world championships (the
2010 constructors' and riders' titles) under its belt - features two more
cylinders and 41 horsepower more than before, while weighing over ten kilos
less. These astonishing figures are a testimony to the technological evolution
that made this exciting model a reality. The bike is available in two different
configurations - Tuono V4 R APRC a choice of three colours: competition black,
sunlit yellow and wing grey.
THE MOTORCYCLE
With its 65° V4 engine unashamedly flaunted and framed by the brushed aluminium
elements of the twin spar frame, the Tuono V4 is a naked clad only with the bare
minimum necessary to let you saddle up and teach it to respond to your will.
Adding yet another touch of aggressiveness is the aerodynamic top fairing tipped
with two polyelliptical headlights and LED indicators at the sharp end, which
gives the bike the unequivocally mean, daunting stare that you'd expect from a
machine with an incredible 167.3 horsepower.
Tuono V4 R boasts more power than ever seen before in a naked, achieved by
reconfiguring the V4 engine of the RSV4 to make it better suited to street
use.The features inherited by the Tuono V4 R from the RSV4 include the exhaust
system with bypass valve, which is two kilos lighter than the system used on the
RSV4 R, and latest generation Ride by Wire throttle control with three
rider-selectable maps (Track, Sport and Road).
The first three gear ratios are now shorter, while the maximum torque value of
111.5 Nm is on tap at 9,500 rpm: characteristics that make the Tuono V4 R a wild
beast at low and mid engine speeds, with the ability to unleash a devastating
hurricane of power at higher engine speeds.
The Tuono V4 R maintains a clear parentage with the
twice SBK world champion in the proportions of the tail fairing, saddle, tank
and side panels, and is one of the best examples of Italian motorcycle design
from the past decade for its perfect balance between formal beauty and function.
The rider will be taming this beast from a riding position tailored to create a
symbiotic relationship between the body and the bike, for unparalleled feedback
through the three points of contact - the saddle, footpegs and handlebars. On
the Tuono V4 R. however, the rider sits with less weight taken up by the arms,
making the bike less strenuous to ride and extraordinarily nimble and
controllable on the road.
The original design of the saddle, which is generously sized and specifically
shaped to comfortably accommodate a passenger, blends perfectly with the style
of the side fairings and tail fairing.
From the vantage point of the saddle and with the broad tapered handlebars
firmly in your grip, you immediately discover that the
APRC (Aprilia Performance Ride Control) version features an immediately
intuitive joystick for rapidly accessing and adjusting the functions of the
second generation electronic dynamic control suite developed by Aprilia to let
the rider explore the physical limits of riding.
THE ENGINE
The Tuono V4 R is the only naked powered by a narrow V (65°) 4 cylinder engine
with unique characteristics. Extremely compact, as slim as a twin-cylinder and
installed in an ultra-compact chassis, the 65° V4 engine is the epitome of
Italian engineering ingenuity.
The Tuono gives away very little to its RSV4 sibling in terms of pure
performance, but in exchange offers a greater fluidity that make it more
enjoyable and rewarding to ride on the road and when carrying a passenger.
Tuono V4
Power 167.3 hp at 11,500 rpm
Torque 111.5 Nm at 9,500 rpm
Rev limiter 12,300 rpm in all gears
To achieve these results, a number of different modifications were made to the
Aprilia V4 engine:
- New valve timing diagram.
- Fixed intake ducts now 20 mm longer.
- Crankshaft flywheel with increased inertia for improved smoothness and overall
balance.
- Shortened gear ratios for the first three gears.
- Engine speed at maximum power reduced to 11,500 rpm on the Tuono V4 R
The narrow V architecture translates into an engine that is incredibly compact
in length, offering advantages in terms of mass centralisation and making it
possible to define a chassis architecture centre of gravity that is both very
low and almost perfectly centralised in the engine and vehicle for neutral,
intuitive behaviour and maximum responsiveness on the road.
The innovative valve timing system (with the chain camshaft driving only the
intake camshaft, which in turn drives the exhaust camshaft via a single gear)
has allowed the use of extremely compact heads (just 250 mm at the rear of the
engine), especially in the area beneath the frame spars, which are thus much
narrower than would otherwise be possible.
A countershaft dampens vibrations even more than in a 90° V engine.
The monobloc crankcase with integrated aluminium cylinder liners ensures maximum
rigidity and consistent performance.
The electronic management system is another example of the 65° V4 engine's
technological supremacy. Full Ride by Wire technology eliminates any direct
connection between the throttle grip and the throttle valves, which are entirely
controlled by a latest generation Marelli control unit that also controls the
ignition and the 4 injectors
Each bank has a dedicated servo unit actuating its own two throttle bodies only.
This means that the aperture of the throttle valves and, as a consequence, the
quantity of fuel injected, can be controlled independently. A solution that
opens up practically infinite possibilities for power delivery control and works
hand in hand with the APRC system.
This technology, adapted appropriately for the prevalently road based usage of
the Tuono V4, offers immediately tangible benefits to the rider, with triple
mapping (adjusting power delivery and maximum power) selectable directly from
the handlebar allowing the character of the bike to be modified to suit the
rider's personal riding style or the track conditions at any time.
T - TRACK: no compromise. All 167.3 hp of power available at the slightest twist
of the throttle.
S - SPORT: maximum fun on the open road. Smooth delivery, maximum power. Torque
limited in all gears for fun yet less demanding riding.
R - ROAD: usability in all conditions. Smooth delivery and power attenuated by
25% across the rev range. Greater usability in all conditions. Ideal for the
city or wet road conditions.
The transmission has also been designed to the meet most advanced criteria to
offer the maximum performance possible. To underscore the racing soul of the 65°
V4 engine, it is mated to a cassette gearbox with a wet sump lubrication system
(with oil in the crankcase). The wet clutch features a mechanical slipper system
for optimised engine braking torque control and stability under hard braking.
CHASSIS
In keeping with the Aprilia tradition of creating state of the art chassis
architectures, the aluminium frame of the Tuono V4 R exploits the strength and
flexibility of cast and pressed elements in a structure that sets new benchmarks
in terms of balance and dynamic efficiency. The result is maximum torsional
stiffness and flexional stiffness optimised for improved feedback.
Unlike the previous generation twin cylinder Tuono 1000R, the frame developed
for the Tuono V4 R has been completely revised with respect to the unit used in
the RSV4 to maximise directional control and stability for a naked capable of
over 270 Km/h - on the track, of course - while maintaining the legendary safety
and impeccable precision typical of Aprilia frames.
This in turn led to new solutions in terms of chassis geometry, such as
modifying the trail and lowering the engine in the frame to lower the centre of
gravity, for exceptionally neutral behaviour and truly catlike high speed
stability.
This means that the Aprilia Tuono is not just a bike with devastating
performance, but one whose greatest strength is precisely the incredible ease
with which any rider can access its full potential. The swingarm also uses the
same constructional technology as the frame and offers the same perfect balance
between flexional and torsional stiffness to contribute to the extraordinary
responsiveness of the Tuono V4 R.
The unique construction technology of the frame and swingarm allows them both to
proudly flaunt the naturally gleaming colour of brushed aluminium, yet another
feature that is increasingly rarer in production bikes that contributes to pure
racing look of the Tuono V4.
The mind-blowing naked from Aprilia comes equipped with the best components
available on the market: Brembo brake system with radial callipers and 320 mm
floating discs at the front (220 mm at the rear), aluminium wheels with a three
spoke design weighing 2 Kg less than the five spoke version, fully adjustable
Sachs upside down front fork with 43 mm stanchions, and Sachs shock absorber
with separate piggy back nitrogen canister featuring adjustable spring preload,
compression and rebound damping and length, to modify the setup of the bike to
suit different riding styles, roads and loads - including a passenger. The
choice of dual-compound tyres is new, with three different sizes approved for
the rear wheel: the 190/55 tyre fitted as standard may be replaced with a 200/55
or a 190/50 tyre to explore the full performance potential of the bike - even on
the track.
