G 450 X

The new BMW G 450 X Sport Enduro is a unique motorcycle that completely rede² nes enduro riding. That’s because it’s been designed from the

ground up to deliver the sort of traction dreams are made of, with a brand new single-cylinder engine and a revolutionary patented swing-arm design.

After extensive testing, the G 450 X is ready, willing and able to take on the toughest competition around.

UNSTOPPABLE – THE NEW G 450 X.

Our engineers set the bar high when designing the new G 450 X,

and resolved to build a motorcycle that would meet the ver y highest

standards in off-road racing. The result is a truly revolutionary frame

design, with a swing-arm pivot point that shares its axle line with the

drive sprocket. This ensures that the length of the drive chain – and

as a result, the ef² ciency of the transmission – is not af fected by the

compression and rebound of the suspension.

It also saves space, meaning there is room for a swing-arm that is

signi² cantly longer than on other bikes with a comparable wheelbase,

for maximum ground contact and traction on any surface. This design

also allows the engine to be placed further back, which means the

vehicle’s mass is now more concentrated around its centre of gravity.

By angling the engine for wards, additional space is created for long,

straight intake pipes that help the G 450 X to meet the latest emission

regulations without compromising on performance.

The motorcycle’s innovative, patented technology has been extensively

tested in competition, with experienced professional racers such as Joël

Smets, Kari Tiainen, Simo Kirssi and Andreas Lettenbichler providing

valuable feedback used to ² ne-tune its setup. This incredible motorcycle

is now available for anyone to buy, and is ready to tackle the toughest

courses the off-road world can throw at it.

TECHNICAL DETAILS:

BMW G 450 X DESIGN CONCEPT

The frame of the BMW G 450 X is a completely new design. It is made

up of exceptionally thin stainless steel tubing with very few bends. The

down tubes run in a straight line directly from the swing-arm mounting to

the steering head, while the top tubes connect the steering head to the

suspension strut. This keeps down the amount of materials used, and

offers maximum strength and stiffness with minimum weight. As a result,

the motorcycle handles impeccably, is highly manoeuvrable and offers

excellent directional stability. This new layout also frees up extra space

for the radiator, which is now a single component, removing the need

for additional hoses and so further reducing overall weight. However,

what makes the chassis truly unique is the way in which the swing-arm

and drive sprocket now pivot about the same point. The swing-arm is

mounted on a steel axle that passes through the transmission output

shaft, meaning that the length of the drive chain remains constant,

whatever the suspension travel. The tension in the chain remains

constant, and the pinion, chain and chain ring wear considerably less

than in conventional systems. This coaxial swing-arm mounting also

lessens the impact of load changes on the drive train. And the swing-

arm itself can be 30 millimetres longer without extending the overall

wheelbase, meaning that better ground contact is maintained in all

situations and power is put down more effectively onto the ground.

Being unstoppable means doing things better than the rest. The design of the swing-arm is nothing short

of revolutionary: for the ² rst time ever on a production motorcycle, its pivot point shares an axle line with the

drive sprocket. As a result, the compression and rebound of the suspension do not alter the length of the

chain, and so do not impair the ef² ciency of the drive train.

It also means that the length of the swing-arm can be signi² cantly increased, without needing

to extend the wheelbase, and that the engine can be positioned further to the rear. These two

factors greatly increase traction and ground contact in off-road riding. As a further unique innovation,

the frame is made almost entirely of straight tubing, offering exceptional rigidity. All these design

innovations offer bene² ts that you’ll feel right away – and never want to be without again.

UNSTOPPABLE TRACTION.

COMES FROM REVOLUTIONARY

FRAME/SWING-ARM DESIGN.

TECHNICAL DETAILS:

FRAME AND PATENTED

SWING-ARM DESIGN

The key to unstoppable performance is an unbeatable engine – an engine like the ultra-modern DOHC single-cylinder unit found

in the G 450 X. Because it is angled forwards, the air intakes are straight and long, ensuring the engine receives all the air it needs

to deliver punchy yet supremely controllable responses right across the rev range. In addition, the innovative

positioning of the clutch directly on the crankshaft minimizes the amount of torque it has to handle, and as

a result its size and weight can be signi² cantly reduced. Naturally, the unit is also fully compliant with EU3

emission regulations.

UNSTOPPABLE TRACTION.

COMES FROM AN OUTSTANDING ENGINE.

The 449-cc single-cylinder engine found in the BMW G 450 X produces

41 horsepower (30 kilowatts) at 7,000 rpm and 43 Newton-metres of

torque at 6,500 rpm. It features an EU3-compliant catalytic converter,

which is homologated for on-road use, and offers all the power you need

for an incredible riding experience. Should you wish to further increase

performance however, simply insert a small engine chip and you can

boost output to 52 horsepower (38 kilowatts) at 9,000 rpm, and torque

to 44 Newton-metres at 7,800 rpm (open version with original silencer

– not homologated for on-road use). The short-cylinder, four-stroke

DOHC engine is another BMW innovation: while the inlet valves of the

compact four-valve cylinder head are actuated via rocker arms, a bucket

tappet is employed for the outlet valve. Digital engine management

and two sequential throttle valves also further improve performance,

and ensure that the engine reacts precisely to throttle inputs. Unlike on

most motorcycles, the clutch is now mounted directly on the crankshaft

and can thus be more compact, as its increased revolutions reduce the

amount of torque it needs to transfer. Furthermore, the engine is angled

forwards, optimizing weight distribution and allowing straighter – and

therefore more ef² cient – intake pipes. The air ² lter is made of a smooth

foam ³ eece and can be changed quickly and effortlessly. Finally, the

standard silencer with catalytic converter can easily be swapped for an

AkrapoviĖ

titanium slip-on system for competition riding (optional, not

homologated for on-road use).

TECHNICAL DETAILS:

ENGINE

To be truly unstoppable, you need outstanding grip, which means maximum ground contact at all speeds and on

all surfaces. The front of the G 450 X features a fully adjustable Marzocchi upside-down fork with 300 millimetres of

travel, which effortlessly handles even the bumpiest terrain. At the rear is a fully adjustable Öhlins monoshock suspension system, also fully adjustable and with

320 millimetres of travel. All this sophisticated engineering has been introduced with one aim and one aim only – making you and your machine unstoppable.

UNSTOPPABLE TRACTION.

COMES FROM A SUPERB CHASSIS.

The rear wheel of the BMW G 450 X measures 18 inches in diameter

and is held in place by a robust aluminium double swing-arm. An Öhlins

suspension strut is attached to this via bolted aluminium brackets,

offering 320 millimetres of travel, and fully adjustable compression and

rebound damping. The spring preload can also be adjusted, via ring

nuts. The 21-inch front wheel features an upside-down Marzocchi fork

and 45-millimetre stanchion tubes. This too is fully adjustable for both

compression and rebound damping, and travel here is 300 millimetres.

Stopping power is provided by a Brembo brake system, with a double-

piston ³ oating caliper at the front, and a single-piston ³ oating caliper at

the rear. The diameter of the front brake disc is 260 millimetres, while

that at the rear measures 220 millimetres. To protect the G 450 X in the

most challenging off-road conditions, the motorcycle also features a

shatterproof lightweight plastic bash plate, which has already proven its

worth in competition riding.

TECHNICAL DETAILS:

CHASSIS

Being unstoppable means being in complete control. And that takes more than the right combination of frame,

engine and chassis. Whether you’re travelling uphill or down, sitting or standing, it is vital that you, the rider,

are always in a comfortable position. The G 450 X is an exceptionally well-balanced machine, with a slim body, and a long, ³ at seat.

And to give you maximum freedom of movement, the fuel tank is located underneath the rider seat.

UNSTOPPABLE TRACTION.

COMES FROM A PERFECT RIDING POSITION.

The design of the BMW G 450 X is at once instantly recognizable as a

BMW machine and highly ergonomic. From the steering head to the back

of the seat, the bike is unusually narrow, offering the rider exceptional

freedom of movement. The fuel tank is located beneath the seat, so it

never gets in the rider’s way, and this makes a major difference when

standing (the ² ller cap is integrated into the seat). The airbox is positioned

relatively high up, underneath the front part of the seat, so it is ver y well

protected from dust and when riding through water. The single-section

seat is made of special moulded foam – there is no cover, substructure

or base, saving further weight. The motorcycle’s wide foot pegs are

extremely practical and offer excellent grip for feet due to their serrated

edges, while the double-butted aluminium Magura handlebars can

be adjusted by up to 20 millimetres, ensuring exceptional control and

comfort.

SLIP-ON RACING SILENCER (NOT

HOMOLOGATED FOR ON-ROAD USE)

Featuring the same design as the standard silencer, the racing

edition is considerably lighter than the standard component (by

one kilogram), due to the absence of the catalytic converter. It can

easily be ² tted in place of the standard silencer, and no further

modi² cations are required. (When ² tted with the racing silencer,

the G 450 X is not homologated for on-road use)

standard components). Exceptionally well made, with racy

styling and a rich throaty sound, the slip-on racing silencer can

be ² tted in seconds. It is suitable for use with either the titanium

racing exhaust manifold or the standard version. (When ² tted with

the titanium racing silencer and/or the titanium racing exhaust

manifold, the G 450 X is not homologated for on-road use.)

CHAIN GUARD

The drive chain of the G 450 X is highly durable anyway, but

the chain guard extends its service life still further. It resembles

a rubber tube in form and covers the chain in its entirety,

protecting it against dirt and reducing wear and tear.

WATERPROOF RACE POCKET
