EICMA: Aprilia NA 850 Mana
The Aprilia NA 850 Mana ushers in a new way of getting about
on two wheels. Practical when needed, sporty when you want, the
NA 850 Mana combines two bikes in one, a genuine motorcycling
revolution.
The Aprilia NA 850 Mana explores new frontiers in mobility, a
modern naked, powerful and fun, with a revolutionary gearbox,
electronically controlled for unique riding pleasure. Thanks
to the innovative NA 850 Mana technology, the bike is able to
satisfy different riding styles and different needs.
The Aprilia NA 850 Mana is today the maximum of advanced technology
applied to a bike. A daring challenge which only Aprilia's extraordinary
technical abilities could take on and win. There is nothing to
match the Aprilia NA 850 Mana anywhere on the world market, a
unique and ultra-advanced design. A bike capable of delivering
great satisfaction in any conditions, from about town trips to
routes demanding a sporty ride. A simple touch on the handlebar
button and the Aprilia NA 850 Mana takes you into another world.
Completely automatic transmission with three mappings, or sequential
gear change with seven gears with the Aprilia NA 850 Mana it
is literally impossible not to find the most suitable configuration
for the particular traffic and/or riding conditions or your specific
needs. Whether tackling an about-town trip or a winding road,
the Sport Gear always performs with the same brilliance and gives
the same riding pleasure. The rider can choose the right solution
for every situation.
The 90° V twin engine is the perfect partner for this type
of gearbox. Compact, brilliant and clean. It is Euro 3 compliant,
thanks to the electronic injection and exhaust with catalytic
converter. High power and torque guarantee a sporty ride, particularly
in acceleration where the Aprilia NA 850 Mana burns up everyone
at the traffic lights, practically unbeatable, not just by nakeds
of the same capacity, but also many sports bikes as well. All
with the maximum riding simplicity. The Aprilia NA 850 Mana is
friendly technology which simplifies life. There is no clutch
lever. Everything is controlled electronically, leaving the rider
free to enjoy the ride. The sequential gear change is controlled
by a convenient command on the handlebars, or alternatively by
a traditional pedal command.
In common with all Aprilias, meticulous chassis design makes
the bike a superb ride. The tubular steel trellis frame is extremely
strong with excellent torsional rigidity. Combined with a single-piece
aluminium swingarm and advanced suspension, it makes the NA 850
Mana able to satisfy even the most demanding rider. The top quality
brakes increase active safety, thanks to the standard setting
braking distance.
 Below are some of
the special features of the design:
90°V engine, four valves per cylinder, Euro 3 compliant
Sequential gear change, electronic control with the possibility
of manual operation with seven gears or automatic operation with
three mappings.
Double spark plug ignition
Electronic fuel injection with single throttle body
Tank under seat
Helmet compartment for full-face helmet
Steel trellis frame with single-piece swingarm
43 mm upside down fork
Side shock absorber
Brakes with radial calipers
THE DESIGN
The concept of utility design always applied to all Aprilia projects
is even more valid in the NA 850 Mana. A sports naked in appearance,
but capable of unique versatility. The NA 850 Mana represents
the perfect mix of sports personality and elegance, thanks to
a modern reassuring design. As on any Aprilia naked, the technical
elements also become design elements. Engine, tank, airbox, frame
and exhaust all help give the NA 850 Mana its special character
and the personality it needs to stand out from the crowd.
A design which is also the result of daring and innovative technical
features. The tank is located lower down under the seat, helping
centralise masses and lower the centre of gravity. Its "traditional"
place is taken by a helmet compartment able to accommodate a
full-face helmet and other objects. The NA 850 Mana is therefore
the first bike to offer a genuine integrated helmet compartment,
uniquely practical and convenient, particularly about town and
on short trips. The compartment is unlocked electrically by means
of a control on the handlebars, a safety lock which prevents
accidental opening.
ENGINE
Without the shadow of a doubt, the NA 850 Mana engine sheds new
light on the future of the bike. Two cylinders, electronic fuel
injection, high torque, but above all innovative transmission
replacing the traditional mechanical gearbox. An engine which
opens up new frontiers in bike riding, whether sporty or otherwise.
An engineering idea which Aprilia has developed by fully exploiting
the technical know-how of its best engineers and the top level
capabilities of its in-house research and development department.
NA 850 Mana: the future of the gearbox
The primary drive is without doubt the focal point of this innovative
engine. Thanks to the electronically controlled sequential transmission,
the rider can choose from various riding styles.
The rider has two possible options:
- Completely automatic: everything is controlled electronically,
the CVT transmission enables the engine to be run at maximum
torque at all times, emphasising pick-up and acceleration. The
electronic control system has three different mappings (Touring,
Sport and Rain), enabling the rider to choose the type of operation
most appropriate to the situation or his own needs.
- Sequential: The rider chooses the gear himself by means of
either the control on the handlebars or the pedal command. A
servo-assisted mechanism acts mechanically on the main pulley,
making changing between the seven ratios extremely rapid.
The rider can switch from automatic to sequential at any time
and in any riding conditions.
The Aprilia NA 850 Mana engine does not in any way make the ride
less enjoyable. Quite the opposite, it adds the enjoyment of
ultra-rapid gear changes which improve the performance of the
engine in acceleration or on demanding routes. All it takes is
a click to pass from one mode to the other, from a relaxed ride
to a sporty ride. The engine therefore multiplies the potential
of the bike.
The 90° V structure was chosen for its torque and power delivery
characteristics and combines perfectly with this type of transmission
850 cc for 75 HP at the crank and torque of up to 8 kgm at particularly
low engine speeds (5750 revs). Figures which give a good idea
of the performance of this engine which certainly does not suffer
from an inferiority complex, even when compared with more sporty
bikes, partly thanks to its incredible acceleration.
The four valves per cylinder are controlled by a single overhead
camshaft with chain drive, simplifying maintenance while at the
same time guaranteeing efficient performance. As is usual for
Aprilia high capacity engines, lubrication is dry sump, with
a separate tank integrated into the engine to keep the weight
of the assembly down.
Engine breathing benefits from the particularly large volumes
of both the airbox and the exhaust. The electronic engine management
involves a sophisticated Weber Marelli fuel injection system
with one 38 mm throttle body and an ignition system with two
spark plugs per cylinder, features which result in optimum combustion
at all speeds, improving performance and reducing pollution.
An engine not just high performance, but also extremely environmentally
friendly. The stainless steel exhaust with catalytic converter
and Lambda probe oxygen sensor make the Aprilia NA 850 Mana fully
Euro 3 compliant.
FRAME
 The
sports personality of the Aprilia NA 850 Mana is emphasised not
just by the engine, but also by the chassis. As with all Aprilia
bikes, the structure chosen for the NA 850 Mana was developed
hand in hand with the engine to guarantee that harmony between
the performance of the mechanics and chassis which has always
been the pride of all Aprilia bikes.
The large-section tubular steel trellis frame sets new standards
of rigidity for its class, perfectly in harmony with the other
characteristics of this innovative engine and guaranteeing a
superb ride. The single-piece aluminium swingarm controls a second
shock absorber. The shock absorber is located at the side to
reduce the length of the bike as far as possible. The wheelbase
in fact measures just 1463 mm, making the bike extremely short
for even a sporty naked.
SUSPENSION
As in all Aprilia bikes, the exceptional quality of the chassis
is also achieved through optimum definition of the type and calibration
of the suspension. The Aprilia NA 850 Mana ar accepts no compromises.
The 43 mm upside down fork provides exceptional smoothness. The
120 mm wheel travel makes the bike equally at home on any route.
The shock absorber, located at the side to help keep the length
of the bike down, is operated directly from the swingarm and
provides adjustments for spring reload and rebound. The rear
wheel travel is 125 mm.
THE BRAKES
The best technology currently available on the market is used
to guarantee maximum efficiency. The radial calipers with four
pistons are reminiscent of the race track. Top level brakes which
give the Aprilia NA 850 Mana unbeatable braking. The 320 mm disks
at the front, a generous standard size for Aprilia sports bikes,
are supported by a 240 mm rear disk brake.
