BMW G450 X


Over the last 80 BMW Motorrad has made off-road time and time again. The is now closely involved in off-road as never before and is premièring an pedigree sport enduro in the 450-cc displacement class.


The new BMW G 450 X is a motorcycle exclusively for enduro sport and the most competitive races in the world. a machine that is ready to the moment it arrives from the

The background to the development of such a is the knowledge that competition-oriented motorcycles represent a parameter growth potential in the motorcycle Markets such as US, Australia, and already register nearly stable sales in the off-road and BMW Motorrad wants to help and stimulate this and other for the long term.

Besides, volume off-road motorcycles the gateway to both popular and motor sport as well as enough potential to also the young generation to rediscover the of motorcycles again. With the of the G 450 X, BMW i s also pointing the way for the upcoming and towards sustainably securing the of the motorcycle in general.

The engine the latest fuel injection and three-way catalytic converter is III homologated and already meets the emissions standards which are ever more rigorous for sports events as well as for vehicles. With these BMW Motorrad is also taking a step towards public of enduro sports in the future.

The unrivalled technical features of the new BMW G 450 X it a driving force and contribute to the of technological competition in this The introduction of the tough enduro BMW G 650 has already pointed the way: a frame and swing arm layout for offroad traction, low weight, chassis and dynamic engine.

BMW goes still further the BMW G 450 X and is not content with constructional traditionally seen in the class. solutions have been in both the engine and chassis in with the cross-country sporting of the house and giving the marque a exclusive off-road profile.

The of the BMW G 450 X is based on keeping the mass as near as possible to the center of and realizing a vehicle configuration adapts perfectly to the requirements of sport. The central element of concept is the amalgamation of the bearing of the rear-wheel swing arm with the of rotation for the driving pinion so is no change in length of the chain on and rebound, minimizing the effects of the drive on the vehicle’s response. consequences of this unequalled approach are a noticeably longer arm for the same wheelbase as the competition with it, maximum traction concrete advantages in enduro with its extreme demands on and machine.

Fundamental to the overall is the saving in length through the of the swinging bearing and pinion axis. Not only does it a longer swing arm, but the high-performance DOHC single-cylinder with an output of 50 bhp could be positioned further to the rear. The was more strongly tilted to the thus creating space for straight intake tracts.

In this way an ideal position was for the fuel injection nozzle and throttle valve fuel system. This also to adapting the engine to meet the of the Euro III exhaust gas norm loss of performance, which is but standard in this motorcycle Further concept advantages optimum protection of the airbox and air flow due to its placement above the in front of the seat.

One consequence of the implemented, centralized concentration of close to the centre of gravity is the tank under the seat. The manifold is positioned below an in the rear part of the seat. The function is signaled by a warning in the cockpit.

The starter is placed in of the engine; the battery is protected dirt and easily accessible behind the control head in the triangular frame. The air filter is a flat wet element, fixed by a mechanism that makes it easy, safe, clean and fast to change. For this, the cosmetic tank cover with a quick-release fastener) is and the air filter drawer is pulled

The intake funnel is positioned at the of the control head whose position is advantageous in water or wherever there is heavy development. The seat of the BMW G 450 X is made a piece of special foam Foregoing a cover and not having a or sump as its base brings advantages.

Another distinctive feature is the relocation of the clutch onto the crankshaft, a position enabled an ingenious frame The frame tubes were straight ahead of the swing arm bring-ing maximum stiffness at the time as minimum weight and use of material. Further plus of this overall arrangement for the radiator. This now had enough to be designed in one piece.

This additional coolant hoses and and a low weight, important for an off-road

The development of the BMW G 450 X focussed on the ergonomic and design of the active riding Starting from the steering to the rear section of the seat, the has an extremely slender waist¬line where the rider sits, maximum freedom of movement. in a standing position, the rider because the absence of the tank at point provides unrestrained and the motorcycle can be kept appreciably

In this configuration the G 450 X is the first BMW to be uncompro-misingly developed for professional racing. Like no other the advantages of the unique construction are revealed to the full in rugged conditions; features such as the concentration of the masses around the of grav¬ity, the engine effects by the unique swing arm mounting, the low wear of chain and pinion, the handling reminiscent of a 250 series motorcycle with prodigious stability, the low weight, the powerful and the high-technology spring elements offer the ambitious enduro rider a number of package and benefits in hard competition limit-less riding pleasure. by the options it incorporates, the G 450 X is the most off-road BMW of all times for hard riding.

A dedicated team of specialist and mechanics, who have also part in intensive off-road privately for many years, has this new model for BMW Motorrad the motto “from passionate for passionate professionals”. The BMW G 450 X continues the expertise in the field of professional sport already consistently in the BMW G 650 Xchallenge.

It weighs about 40 less than the G 650 Xchallenge for the same output and, the first draft to the last is perfectly tailored to the requirements of the and success-oriented enduro sports As a completely special and absolutely motorcycle, the BMW G 450 X is a genuine sports and it goes without saying it has all parts required for MOT approval as This means that other vehicles in this it’s no problem to ride the BMW G 450 X to the on its own two wheels.

The innovative, patented of the single-cylinder sports enduro was put to the test in all relevant highly-competitive through-out the 2007 season by and successful racing professionals as Sascha Eckert, Simo and Joël Smets who were to harmonize and further develop the Today the motorcycle comes for offroad racing and competitions at the level and with approval for road traffic without modification straight from the

Thanks to great traction at low smooth engine output and revving, superior riding with extremely light best balance in slow sections and enormous stability at speeds, not only professional or enduro riders, but even sport novices have no in mastering this racing

To corroborate the extremely sporty qualities, BMW Motorrad has a works team that already part in different Enduro events with the G 450 X during the phase and will continue to it in the Enduro world championship of the E2 for example, or the German cross championship (GCC).


The model designation G stands for a new of sporty motorcycles in the mid-range and cc segment, distinguished by its consistent easy handling, tracking and safe riding qualities. For power, the focus is placed on cultivated, dependable and economic engines.

G stands symbolically for a thought out ‘G’eneral concept and down to the last detail, for the of the whole vehicle, for the masterful of all individual components in respect to an whole. G also stands for riding qualities and pure, riding pleasure.

The range of possible uses of the G covers a wide spectrum. the light allrounder ideal for to the agile super moto and the robust hard enduro up to the sports enduro with qualities.

While the models of the 650 are based on a common technical but are differentiated by the consistent configuration and product features for their purpose, the high performance G 450 X is the first representative of a motorcycle that shows itself to be competitive and success oriented, the sporty spearhead of the G-series as a Common to all G models is the high-grade of the product and proverbial BMW quality, of where it is produced.

Specially to customers’ riding styles and the of the G 450 X, exclusive training is in preparation and progressively supplement the offers for the new

Development, Technology and Design

a technical point of view, the BMW G 450 X has no It is a brand-new development where such as weight saving perfect and uncompromising configuration to the of the competition-oriented offroad racing at the forefront of the specification for the developer.


Enduro racing an enormous stress on the materials. The to moto cross sport is the machines tuned to the limits of are strained to the limits so their must satisfy the highest of all Due to the extreme range of use, the of the G 450 X were extremely complex and new paths had to be taken in some

The testing included the toughest performance with meter-high freezing cold up to extreme water splashes and continuous in extremely dusty surroundings sand and stone impacts. The must be able to withstand all conditions reliably and sustainably. any other type of motorcycle is with such requirements in combination.

The testing program included testing in a real environment as well as numerous tests and trials on special tracks were correspondingly and intensive. From the very this meant the BMW G 450 X had to prove in the environment where it wants to part later in contests for the on the courses of national and international and cross racing where the weakness of rider or machine can to defeat or failure. Long-term in terrain in both Spain and rounded off the overall program serial production was reached.

The 449 cc single-cylinder DOHC 4-… of the G 450 X was developed by BMW. The compact head of the short-… four-valve unit houses the technical of the K 1200 S: for example, the intake are operated by follower valves; the control is implemented by tappets. A configuration distinguished by high peeds.

Optimum performance that the requirements of the Euro III exhaust gas is realized by fuel injection oxygen sensor regulation and a throttle valve system ensure that the engine more sensitively to throttle The crankshaft and conrod are fitted roller bearings and the weight-optimized two piston is forged.

A balance effectively reduces the vibrations of a single-cylinder engine. The constant five-speed transmission was widely for optimum connections in racing. The coupling sits directly on the and is configured as a wet clutch with a diaphragm. In contast to conventional the BMW G 450 X clutch is considerably more and has a smaller diameter with the number of discs.

Contrary to the geared-down clutches, this is because the clutch only to transmit a correspondingly reduced on the transmission input shaft. The is operated by a cable.

The engine is fed oil by a wet sump lubrication system. Two oil a pressure pump and a suction use the same volumes of oil to lubricate the and the crankshaft. The two integrated oil sieves and oil are easy to access from the side of the engine for replacement.

The of oil of approximately one liter can be checked via an glass.

An intermediate shaft integrated ventilation function the power from the crankshaft to the and means that the crankshaft of the G 450 X turns backwards. The cylinder is forward by approxi-mately 30 degrees, the center of gravity to be moved in the of the front wheel thereby the suspension. A further advantage of the cylinder is the creation of space for the air ducting that can now come from above and virtually promoting optimum performance.

The of the BMW G 450 X, with a compression ratio of 12. 1, is by an electric starter; an additional is unnecessary thanks to a powerful and fuel injection with reliable starting action. An decompression function with a force valve lifter the power demanded by the starter.

when the machine has to travel for periods at higher revs in and slow off-road sections, the is never excessively thermally thanks to its large-volume, single-piece A fan behind the cooler provides air flow rate at low flow

The production exhaust system is of stainless steel and the catalytic is fitted in the silencer (absorption For exclusive use in competitive racing, purely sporting end silencers are as special equipment and it is possible to to the extreme “race” mapping in the engine control unit.

BMW G450 X

the powerful alternator and electric the high-performance engine of the BMW G 450 X weighs no than the aggregate of competitor (less than 30 kilograms). The power and torque data are not yet


The chassis of the BMW G 450 X is a completely new that uses selected components and materials. The years of experience of BMW Motorrad flowed the development of the chassis. The main in the geometry and overall configuration of the was to meet the especially high of off-road racing.

The results are excellent properties in with ease of handling, maneuverability and extreme tracking

Innovative frame concept.

The layout is based on the experiences of the engineers, the know-how from racing and attendant research and work. The knowledge gained earlier rally sport was also incorporated. The frame of the BMW G 450 X is an new develop-ment that differs in from all constructions of the competition.

In the part it consists of thin but high-strength stainless steel tubes and is welded to the node with forged parts for the purpose. No additional surface is necessary. The entire main weighs merely 8.6 kilograms and is by excellent stiffness.

The lower bow of the tubes runs directly the swinging axle straight to the head. On the other hand, the bow creates a direct con-nection the suspension strut mount and head. The wheel forces are centrally on the frame over the strut so that the light frame that is bolted to the frame and is formed by aluminum profiles now only needs to the weight of the rider.

All in all this enables the optimum flow of requires minimum use of material, allowing a hitherto unrivalled of rigidity to weight.

The 18-inch wheel is suspended in a robustly two-arm swing arm made aluminum square profiles supports a directly linked central suspension strut a generous spring travel of 320 mm. high-technology element is variably in pressure and outward … as well as in the spring pre-tension. The of the 21-inch front wheel is by a 45 mm upside-down fork by Marzocchi absorbs even the roughest with a spring travel of 300 mm and is fully adjustable.

A powerful sys¬tem with double-piston caliper from Brembo the deceleration of the BMW G 450 X. The front single disc has a diameter of 260 mm, the rear measures 220 mm.

In order to live up to the the off-road conditions, the BMW G 450 X has a light, resistant and highly stable underride protection fitted as and that has already proved in racing. The motorcycle also has a Magura aluminium handlebar guarantees optimum control on all

Patented swing arm mount.

The finesse in the chassis sector and a feature of the BMW G 450 X is the coaxial mount of the arm and chain pinion. The swing arm has been mounted through the gearbox output so that is no longer any change in length of the on compression and rebound over the spring travel. The chain remains constant independent of the position; the pinion, chain and ring are subject to less than in conventional constructions.

A positive effect on the riding is that the effect of changing on the powertrain is now noticeably reduced.

to the patented coaxial mounting of the arm and drive chain pinion a wheelbase at competition level, the arm is 30 mm longer, markedly improving the properties. The rear wheel longer in contact with the in all situations, keeping the driving better on the surface. Also, with the competition, a significantly length adjustment range of the wheel results which different pinion and chain combinations can be used with the chain with no problem.

a pinion has to be replaced, the swing arm be removed; however, in comparison to concepts, this is not a particularly consuming task. An experienced can replace the pinion in about 15 and, because of the much wear of the entire final the pinion needs to be replaced often then by the competition.

The looks of the BMW G 450 X immediately make the affinity to BMW Motorrad. The dynamic allows the new motorcycle to be identified as a member of the BMW enduro world, the striking element is the typical beak also the distinguishing shared by all GS models.

The optical also expresses pure performance with the associated This results in the look and of a fascinating vehicle that has the to “ride to win” in competitive

The color concept of the G 450 X is oriented to the G 650 The standard color is “racing with blue accents of BMW which highlights the affiliation to the G family and the new, sporty line from BMW.


The exact technical of the BMW G 450 X have not yet been finally The maximum output is around 37 kW (50 with a best torque of approximately 35 lb-ft. The overall with full tank is 120 kg which means the BMW G 450 X is lighter the current best weight in this class.

This is all the more impressive because is a vehicle with fuel catalytic converter, electric and Euro III homologation that the way to the future of the enduro sport.

The geometrical data of the chassis is to the last fine tuning and will be made known at a date.
