2012 Aprilia Tuono V4R & V4R
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
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 and Tuono V4 R APRC - and in a choice of three
colours: competition black, sunlit yellow and wing
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
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
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 Tuono V4R 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
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 V4R
The Aprilia 65° V4 engine specifications
Engine capacity: 999.6 cc
Architecture: 65° V4
Crankcase: monobloc with integrated crankcase liners
Timing system: 4 valves per cylinder operated directly
by a camshaft driven by a mixed chain/gear system
(lateral timing chain and central gear train)
Fuel system: electronic injection with a single injector
per cylinder and integrated independent Ride by Wire
system for each bank. Three maps selectable from the
handlebar (Track, Sport and Road)
Compression ratio: 13:1
Gearbox: 6-speed direct-control cassette type gearbox
Clutch: Multiplate wet clutch with mechanical slipper
Electronic management: Magneti Marelli control unit
managing ignition, injection and Ride by Wire system.
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
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.
APRILIA TUONO V4 R APRC
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
- 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;
- AQS (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
- 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.
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
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.
