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.
