2012 Aprilia SRV 850
Aprilia SRV 850 redefines the
edge of the scooter world limits.
Power, set-up, sporty spirit, design:
everything about the SRV 850 recalls the technical,
performance and aesthetic standards of Aprilia superbike.
The style is clearly reminiscent of the Aprilia superbike
world. No fan will have trouble recognising the aesthetics
the stylistic standards in the new SRV 850 which,
together with the performance, contributed to confirming
Aprilia motorcycles as the point of reference in the
world of competitive motorcycles.
Aprilia SRV 850 takes its origins based on the GP
800, the maxi two cylinder launched by Piaggio Group
in 2007 which established itself as the most powerful
scooter in the world. The Aprilia engineers enhanced
that revolutionary project, transferring to the SRV
850 the know-how which stems from decades of victories
on tracks all over the world and which Aprilia has
always transferred to its most sporty bikes such as
the Aprilia RSV4, the SBK 2010 world champion, and
the muscular motard Dorsoduro 1200.
Evolved in engine performance, revisited in weight,
riding set-up and aesthetics, SRV 850 brings to the
scooter world the philosophy of performance without
compromise which is written into the Aprilia DNA.
NOT ONLY POWER: A UNIQUE ENGINE
The Aprilia SRV 850 engine is the first and only
90° V two cylinder scooter engine and it makes
the maxi from Veneto the fastest and most powerful
scooter ever manufactured anywhere in the world.
Liquid cooled, equipped with electronic injection,
with distribution of 4 valves per cylinder and twin-spark
ignition, the engine has a displacement of 839.3 cc.
Thanks to a new optimisation of the engine control
system, it now reaches a maximum power of 55.9 kW
(76.0 HP) at 7,750 rpm and a maximum torque of 76.5
Nm (7.8 kgm) at 6,000 rpm, specs which place the new
SRV 850 at the top of its category. Two new oxygen
probes (lambda) allow the engine control unit to optimise
management of the fuel-oil mixture for the two cylinders,
all to the advantage of combustion, obtaining a regularity
of operation at idle speed and a progressiveness and
torque flexibility at medium rpms which are a reference
point for this type of engine architecture.
The new system guarantees maximum efficiency in terms
of fuel economy and emissions control so much that
they already meet the future (stricter) requirements
of Euro 4 approval.
But it is not just power that the designers had in
mind when they conceived this extraordinary engine:
crankshaft and transmission group were designed with
a rotational motion opposite that of the wheels in
order to have a significant reduction of rotating
inertia and the gyroscopic effect: by doing this the
handling and quick entrance into turns of the Aprilia
SRV 850 is increased.
On Aprilia SRV 850 the engine is secured in a completely
integrated way to the frame thanks to an elastic mounting
to contain vibrations and the final drive is entrusted
to a robust, but sophisticated, Regina Z-ring sealed
The exhaust system, completely free of the frame
in order to keep vibrations to a minimum, is a 2-in-1
system which terminates in an aggressively styled
silencer with heat shield.
THE STYLE OF THE APRILIA MAXI
SRV 850 brings the style of the Aprilia maxi bikes
to the scooter world.
If the eyes are the mirrors of the soul, the front
end of the SRV 850 leaves no doubts as to the nature
of the first Aprilia two cylinder scooter: the style
which made the RSV4 popular, the SBK 2010 SBK World
Champion bike, is offered here in its entirety. The
triple headlight, the dynamic air intakes under the
headlight assembly, the racing fairing designed in
the wind tunnel, are all elements which the SRV 850
has in common with the bike that revolutionised the
supersport world. The colours of the livery recall
the colour range of its "sister", the RSV4,
including the two-tone Black-Red which characterises
the Factory version of the Superbike from Veneto,
the one that Max Biaggi rides in world championship
Even the front mudguard and the mirrors, which house
the built in turn indicators, are faithful to the
Aprilia racing style, as is the design of the half-handlebars:
the two arms are made of aluminium and the new hand
grips emphasise its sporty nature. The new instrument
panel, in perfect Aprilia Racing style, is at the
same level as the best supersport bikes. A large,
central LCD is combined with the large analogue instruments
(speedometer and rpm indicator), a true on board computer
with a vast number of functions (including: double
trip odometer, total odometer, service LED, radiator
temperature) selectable with a "mode" button
located on the handlebar.
The large saddle, made in Hi-Tech material, is in
line with the sport design but offers great comfort
for rider and passenger. The sleek and slender rear
end of the SRV 850 ends with a spectacular LED technology
light assembly which the new maxi two cylinder from
Aprilia shares with the Dorsoduro 1200, another “extreme”,
bike, standard bearer of the Aprilia maxi bike muscular
sportiness: a family of vehicles which the SRV 850
is a full member of, bringing unique sport characteristics
to the scooter world without compromises, not even
FRAME AND CHASSIS
The generous power of the Aprilia two cylinder’s
engine demands a superbly rigid chassis. The double
cradle frame of the Aprilia SRV 850 is made of steel
trellis pipes with reinforcing and rigidity plates.
Simulations and road tests have demonstrated that
the SRV 850 has a coefficient of stability at full
power similar to a motorcycle (1 rad/sec) and almost
twice as high as a conventional scooter. The high
level of rigidity translates into an extraordinary
sensation of riding control which also stems from
the 5 kg lightening realised on the RSV 850. The new
sport maxi scooter from Aprilia leans into bends like
a sport bike, reaching angles of 45°, always holding
a neutral behaviour and extraordinary road holding.
Even analising the suspension department it is easy
to see how much Aprilia motorcycling know-how was
passed on to the new SRV 850. At the rear there is
a swingarm made of cast aluminium and secured directly
to the side plates of the frame. It is clamped by
suspension linkages that are dominated by a horizontally
mounted, lateral hydraulic monoshock absorber, adjustable
to seven different preload settings.
Compared to the GP 800 the fork made in aluminium
with large 41 mm stanchions - adopts a more sustained
calibration resulting in significant improvement of
dynamic control of the vehicle, improving braking
and leaning stability.
The wheel rims, 16” at the front and 15”
on the rear are manufactured in aluminium to minimise
unsuspended mass and guarantee riding precision. Overall
performance is also helped by standard equipment radial
tyres, 120/70 at the front and 160/60 on the driving
The braking system at the front uses Brembo Gold
Series double piston floating callipers and two 300mm
semi-floating steel discs. On the rear the floating
calliper with two opposing pistons acts on a 280 mm
steel disc. The piping covered in metallic trellis
and the levers which can be adjusted to 4 positions,
are further testimony to the attention placed on realisation
of the braking system. The Aprilia SRV 850 is even
equipped with a parking brake operated by a practical
lever on the right of the leg shield.
