Following is a lightly edited and translated text version of the huge BMW .pdf press release. Following that are images of the torque and horsepower curves, available colors and a chart comparing the differences in the three bikes (below). Photos and text courtesy of BMW AG.
BMW Motorrad made a big announcement at the 2006 INTERMOT Motorcycle Show in Cologne, Germany with the widest and most varied model range in the history of the Company.
The all-new single-cylinder model series is making its world debut with a fascinating range of three brand-new motorcycles quite different in their features and character, the G 650 Xcountry, the G 650 Xchallenge, and the G 650 Xmoto.
Including the new single-cylinder model series, the BMW Motorrad model range is now made up of no less than 19 different models. With their characteristic features, these models meet all kinds of customer wishes and preferences absolutely perfectly in the segment above 500 cc, offering a very attractive choice in the respective motorcycle categories.
More sporting than ever before, but without neglecting those classic BMW virtues, all BMW motorcycles offer a host of innovations and trendsetting safety technologies. Indeed, the fully controlled three-way catalytic converter introduced on BMW motorcycles more than 15 years ago is now obviously a primary feature on all models, just like ABS anti-lock brakes.
BMW Motorrad has been the benchmark in active safety for a long time, with all models in the range (except for the BMW HP2 Enduro) becoming available with ABS straight from the factory in the last five years. And in July of last year the fourth generation of ABS anti-lock brake technology ever since the start of production of this feature in 1989 was presented to the international press together with BMW Motorrad’s new ASC Automatic Stability Control. Together, these two systems once again underline the leadership in technology of BMW Motorrad and the Company’s leading position in the area of active motorcycle safety.
The current model range is younger than ever before with the exception of the K 1200 LT Luxury Tourer maintaining the same features as in the past, not one single model has been in the market for more than 21/2 years. Based on a broad range of development activities in recent years, therefore, the entire model line-up has been totally renewed from the ground up ever since the beginning of 2004.
And in the same period not only highlights in technology such as the Evo-Paralever and the cast single-unit swing arm in combination with toothed belt drive have been introduced as new features, but also world-first achievements such as the Duolever, the air spring damper system, Electronic Suspension Adjustment (ESA) and mass compensation via the swing arm. Further progressive technologies adapted and carried over from automobile construction, finally, such as anti-knock engine management and xenon headlights, round off the leadership in innovation so characteristic of the brand.
The new Single-Cylinder BMW G 650 X Model Series
Introducing the new range of single-cylinder models, BMW Motorrad is broadening its model line-up with a clear focus on additional target groups. Proceeding from the same technical foundation, the Company has created three new motorcycles absolutely different in their features and characteristics: the G 650 Xchallenge Hard Enduro, G 650 Xmoto Street Moto, and the G 650 Xcountry Scrambler.
With their outstanding product substance, their purist looks, and their exceptionally sporting riding characteristics, these single-cylinder models are filling attractive niches in the market. And through their low unladen weight of less than 160 kg or 353 lb according to the DIN standard, they offer dynamic performance for both the connoisseur and the sports-minded rider. Market launch of the new G 650 X model series is planned in good time for the beginning of the season in spring 2007.
These new machines with the smallest engines in the BMW model range offer particularly the young and young-at-heart motorcycle rider exactly the right entry into the world of BMW motorcycles, but are not entry-level bikes in the conventional sense of the word: On the contrary, the G 650 Xchallenge Hard Enduro will thrill the customer who wishes to really benefit from the enormous off-road potential of his machine. The G 650 Xmoto Street Moto, in turn, with its very impressive active riding qualities, offers the genuine enthusiast a new dimension in riding pleasure.
The G 650 Xcountry Scrambler, finally, stands for carefree riding pleasure and nimble performance both on the road and off the beaten track. Indeed, this unique machine is able to meet all kinds of requirements and offer virtually all riding qualities ranging from city use via country roads and small, winding lanes, all the way to off-road tracks presenting the most challenging requirements.
The G 650 Xcountry therefore conveys the classic but relaxed feeling of riding a genuine Scrambler as well as the concept of wandering on your motorcycle into today’s world in a most modern style. And last but certainly not least, riding pleasure is guaranteed under all conditions and in every situation, since the G 650 Xcountry offers the same outstanding engine and running gear qualities as its two very sporting sister models.
All three of these new models are powered by the single-cylinder carried over from the former F 650 models now optimized for even better performance and minimum weight: In the G 650 X-models, the upgraded engine now develops maximum output of 39 kW (53 hp) at 7,000 rpm, reaching maximum torque of 60 Nm (44 lb-ft) at 5,250 rpm. And it almost goes without saying that the engine’s well-known virtues such as superior reliability, motoring refinement, economy, and environmental friendliness have been enhanced to an even higher standard than ever before.
Yet a further improvement is the even more dynamic surge of power from the four-valve engine now made possible by the lighter crank drive and a number of other modifications. The rear wheel, finally, is driven on all three model variants by an O-ring chain.
The bridge-type tubular frame made of steel with cast aluminum side sections and the bolted-on aluminum rear frame, together with the rear-wheel swing arm made of cast light alloy and a number of other high-quality components, characterize the suspension and running gear concept of the entire G 650 X model series. All components are the same on all three models.
Intelligent lightweight technology with a high degree of overall integration of the various components allows particularly low weight for a motorcycle in this class between 156 and 160 kg (344 and 353 lb), depending on the model (DIN unladen weight with 90 per cent tank filling). Dry weight, in turn, is between 144 and 148 kg or 318 and 326 lb.
Various set-ups and versions of the upside-down telescopic fork as well as the rear suspension elements give each model its own special character and riding features. The Xchallenge, for example, comes with a particularly elaborate air damping system, while the Xcountry and the Xmoto feature a spring strut adjustable for length.
The wheels and their dimensions, in turn, are tailored to each specific purpose, the Street Moto featuring 17-inch cast light-alloy rims, the Scrambler running on 19- and, respectively, 17-inch spoke wheels, and the Hard Enduro featuring 21- and, respectively, 18-inch spoke wheels highlighting the specific character of each machine.
The brake systems also differ from one model to another: The single-disc front-wheel brakes on the Xcountry and the Xchallenge each measure 300 millimeters or 11.81´´ in diameter and come in each case with a double piston brake caliper, while the Xmoto features a four-piston brake caliper interacting with a brake disc measuring 320 millimeters or 12.60´´ in diameter.
A feature truly unique in the segment of highly specialized single-cylinder motorcycles but nevertheless quite natural on a BMW is the optional availability of light and compact two-channel ABS for even greater braking performance. And it also goes without saying that the ABS anti-lock brake system does not in any way restrict the ambitious sports rider wishing to enjoy himself off the beaten track or on special circuits reserved for racing, since the system may be deactivated on demand.
And naturally, the off-road rider enjoying the Xchallenge benefits from the same freedom whenever he or she wishes. Again reflecting the usual standard of BMW Motorrad, the G 650 X models may also be customized by a wide range of accessories and special features tailored to each model.
Indeed, the new models are not only the successors to the former single cylinder machines, but rather round off the range as a whole, since both the F 650 GS and the F 650 GS Dakar are to remain in the model line-up in 2007, with production continuing at BMW Motorrad’s Berlin Plant.
The most important features of the new G 650 X model series at a glance:
- Sporting and emotional design characterized in particular by lightweight features.
- Fast-revving single-cylinder power unit developing maximum output of 39 kW (53 hp) at 7,000 rpm and peak torque of 60 Nm (44 lb-ft) at 5,250 rpm.
- Crankshaft running in anti-friction bearings and an even lighter alternator reducing free mass forces.

- Model-specific range of accessories and optional features.
The new single-cylinder models were developed under the leadership of BMW in cooperation with Aprilia S.p.A., Noale, Italy (Piaggio Group). Production is by Aprilia in their North Italian Scorzè Plant, naturally fulfilling all of BMW’s strict quality standards. And as on the F 650 models, the power unit comes from Austrian specialist Rotax, again following the specifications and requirements made by BMW Motorrad.
In their overall concept, the three new models, using largely the same parts and components on the engine and frame as well as the same main features, seek to offer a very different and distinctive character in each case (see engine specification chart below).
The truly convincing single-cylinder power unit already featured in the existing BMW F 650 model series to this day the benchmark in its class in terms of refinement, smoothness, fuel economy, and emission control sets the foundation for the engines in all new G 650 X models.
Reflecting the different sporting requirements and demands made of each model, a number of components have been modified to reduce the weight of the new motorcycles by approximately 2 kg, enhancing the engine’s fast-revving response and performance and boosting engine output by 2 kW.
As a result, the power unit not only offers maximum output increased to 39 kW or 53 hp at 7,000 rpm and peak torque of 60 Nm or 44 lb-ft at 5,250 rpm, but also even more dynamic performance and a greater athletic character in every respect.
Even lighter than before, the alternator minimizes the free mass weight of the entire crank drive system running in anti-friction bearings, giving the single-cylinder even more spontaneous and athletic performance. The balance shaft serving to optimize smoothness and running refinement has been retained, with the new starter and alternator cover made of magnesium making a significant contribution to the lower weight of the engine. The redesigned four-valve cylinder head, finally, serves mainly to connect the power unit ideally to the frame and suspension as a load-bearing element.
Engine management is provided by BMW BMS-C II electronic engine control responsible not only for the concept of manifold injection, but also for the dual ignition system. Indeed, BMS-C II engine management even features model-specific control maps tailored to the various motorcycle concepts. And thanks to the all-new stainless-steel exhaust complete with its oxygen sensor and three-way catalytic converter now moved higher up than before, as well as the precise engine set-up, the short-stroke power unit significantly outperforms the EU 3 emission standard.
The proven valve drive system with its timing chain, two overhead camshafts and cup tappets, as well as the aluminum radiator cooling system, all remain unchanged.
The gearbox likewise remains the same as before, while the final drive ratio on the chain sprocket has been modified, with a 15-tooth pinion and a 47-tooth sprocket on the G 650 Xchallenge providing a shorter ratio than on the other two G 650 X models with their longer 16:47 ratio.
The different roll circumference on the rear tyres, finally, also affects each model’s riding dynamics. Yet another new feature is the dry sump oil tank to the left behind the cylinder, contributing to the perfect concentration of masses around the motorcycle’s centre of gravity and thus promoting the unique handling of each model to an even higher standard.
Ease of maintenance with service intervals of 10,000 kilometers or 6,000 miles unusually long in this segment remains at the same high level as before.
Highly stable lightweight frame made of steel and aluminum. The particularly light frame is the same on all three models in the G 650 X series and is made up of four highly stable modules: The welded main frame made of steel profile sections, aluminum castings bolted on to the main frame around the swing arm mounting point, the aluminum lower section holding the engine in position, the forged aluminum auxiliary frame serving to take up spring strut forces, and the aluminum frame bolted on at the rear.
With its appropriate use of materials specifically chosen at each point and tailored precisely to load requirements, this concept makes a significant contribution to the minimization of overall weight which is precisely why the various models weigh a mere 156 kg/344 lb (Xchallenge, the lightest model) to 160 kg/353 lb (Xcountry, the heaviest model) with a full tank according to the DIN standard.
The intelligent mix of materials on the frame offers a number of other benefits: The aluminum castings around the swing arm mounting point the rider is bound to touch with his boots are epoxy-plated to prevent any such contact from leaving behind unwanted marks.
At the same time the swing arm mounting point has been modified in its configuration, the swing arm now pivoting exclusively on the main frame and not on the engine block, and being positioned relatively close to the pinion. This not only serves to provide even faster drivetrain response, but also reduces the tolerance (less slackness) of the drive chain.
Light rear frame and lower section made of aluminum. The rear frame is bolted on to the main frame, allowing easy and low-cost replacement in the event of damage. To make the rear frame resistant to even the highest loads, high-strength aluminum forgings are welded into the ends of the epoxy-plated aluminum frame tubes bolted on to the main frame.
The lower frame section holding the power unit at the front boasts the same very special lightweight technology. Double swing arm made of cast light alloy. The extremely stable, double aluminum swing arm also comes with top quality epoxy-plated surface finish.
Made of cast aluminum, the double swing arm is heat-treated in the production process in the interest of even greater strength and stability provided by the more consistent grain structure of the material. Wheel guidance on all models in the BMW G 650 X range is provided by a spring strut pivoting at the top on a forged aluminum mount.
This ensures smooth and consistent distribution and flow of forces, since the forged aluminum support rests itself on two points first, on the side sections of the frame, and second, on the cylinder head itself through a bolted connection and, in the immediate vicinity, on the stable connection linking the cylinder head and the frame of the motorcycle.
Upside-down telescopic fork with different spring travel on each model. The upside-down telescopic fork (USD fork) is one of the suspension components identical on all three models in the new BMW G 650 X model range. The different character of each model is borne out by different spring travel, a different set-up, and differences in design and configuration around the wheel mounting point.
A further feature on the Xmoto and Xchallenge is adjustment of the telescopic fork both inbound and outbound. With tube diameter of 45 millimeters or 1.77´´, forged aluminum fork bridges, and wheel axle diameter of 20 millimeters or 0.79´´, the telescopic fork is extremely strong and torsionally resistant, ensuring supreme directional stability at all times.
Tank fitted in the frame triangle for optimum weight distribution and concentration of masses. The position of the fuel tank in the frame triangle beneath the seat, a concept already proven on the F 650 GS, has been carried over to all three single-cylinder models on account of its obvious benefits, with optimum concentration of masses near the motorcycle’s low centre of gravity.
Made of a special plastic material, the fuel tank has a capacity of 9.5 liters or 2.1 imp gals and is filled from the right through the lockable tank filler pipe. Even though this fuel capacity may appear to be relatively small at first sight, it is sufficient for a cruising range of up to 250 kilometers or 155 miles, since the single-cylinder power unit is very fuel-efficient.
Light and modern two-channel ABS quite unique in this segment. As an option, the G 650 X models are available straight from the plant with new two-channel ABS from Bosch, the latest generation of BMW Motorrad ABS already featured on the F 800 S/ST and the R 1200 S.
The particular advantages of this anti-lock brake system are not only compact dimensions and low weight of just 1.5 kg or 3.3 lb, but also a high standard of precision and quality in controlling the brakes: The pressure modulator masterminds optimum brake pressure in the ABS mode via intake valves with linear control, keeping the control intervals very fast and precise.
And a further advantage of the modern valves with their infinitely variable cross-sections is that the rider feels only a very weak pulse effect in the brake levers. Enhanced diagnostic functions round off the benefits offered by this modern and sophisticated ABS control system.
The wheel speed sensors, for example, automatically monitor their distance from the sensor wheel and thus contribute to the supreme standard of safety offered by the system. To ensure an optimum and consistent pressure point at all times, the brake system comes with steel-reinforced brake lines even on models not fitted with ABS.
A further point is that the rider is able to deactivate the ABS anti-lock brake system when riding off-road under particularly sporting conditions or when enjoying his machine on a closed circuit. And last but not least, all models fitted with ABS come complete with a 12-V power socket. Features and equipment giving great attention to each and every detail.
The lightweight concept is also maintained consistently with all the motorcycle’s attachments and auxiliary units revealing great attention to detail: The footbrake and gearshift levers are made of light, forged and therefore highly stable aluminum.
The gearshift lever comes complete with a spring-loaded, folding boom at the side, the footbrake lever, through its rolled mounting, allows particularly sensitive operation of the rear wheel brake of particular significance on the Street Moto.
The side-stands on the Xchallenge and Xmoto are made of forged aluminum, the number plate supports and direction indicators can be easily removed for sports riding on a closed circuit. And again last but certainly not least, wide, zig-zagged footrests ensure safe support and stability.
The high-strength light-alloy tubular handlebar comes in conical design for maximum surface contact at all fastening points despite minimum weight. The handlebar supports varying in height on all three models are mounted on rubber holders in the forged fork bridges as a solution efficiently absorbing any unpleasant vibration without reducing the direct feel of the handlebar so important to the demanding rider.
The cockpit is intentionally purist in design and configuration, with clear and easy-to-read instruments informing the rider at all times of his speed, the time of day, and the distance he has covered. Two trip counters may be activated at the touch of a button, and the cockpit also presents a battery charge reading. In the interest of enhanced flexibility, the instruments may be converted by an authorized workshop to either miles or kilometers, whatever the rider requires.
The rear lights come in cutting-edge LED technology ensuring a rapid response, above-average service life, a high degree of light intensity, and power consumption kept to a minimum. The direction indicators come as standard with white lenses.
Reflecting the technology usual in this class, electrical energy supply and the cables in the electrical system retain their conventional technical features. The battery is readily accessible behind the handlebar unit to the right beneath the fairing.
All models in the G 650 X series are registered for riding with a passenger. The passenger kits available as special equipment on the G 650 Xchallenge and G 650 Xmoto are made up of special handles and high-quality, forged footrest supports.
And a final advantage is that converting the machines for riding with a passenger does not require an entry in the motorcycle’s homologation documents. 2.2 Specific Model Components and Distinctions. In conjunction with the light but stable frame and the high-quality suspension components, the powerful and refined engine sets the foundation for superior performance, exceptional handling, and very good tracking directional stability all the way to top speed.
While all three models naturally share these fundamental qualities at the same very high level, they differ from one another in terms of their character and riding features through various design elements and items of equipment, as well as their different suspension geometry and set-up. Apart from the handlebar mounts, the seat, headlights and various design features, particularly the wheels and tyres differ from one another, as well as the brakes and rear spring struts.
Differences in suspension geometry are ensured by the spring travel, the size of the various wheels, as well as modified mounting points for the front wheel. And last but certainly not least in this context, the final drive ratio is specifically tailored to the purpose and character of each individual model.

Conical in shape, this tailpipe made of carbon-fiber-reinforced plastic adds extra sporting flair and character to the machine. The muffler unit itself may be removed for sports riding on private tracks and circuits.
Together with the titanium manifold described below, the titanium sports muffler helps to reduce weight by approximately 2.8 kg or 6.2 lb. Titanium exhaust manifold. The extremely light but highly resistant material used for the exhaust manifold takes on its characteristic colour on account of the hot exhaust gas and is acknowledged by the connoisseur as a particularly sophisticated component.
Carbon-fiber trim panels on the exhaust system. Carbon-fiber trim panels replacing the regular heat protection panels on the exhaust manifold, silencer connection and muffler body offer particularly sporting and dynamic flair. High-quality aluminum trim panels.
