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.

BMW G 650 Xchallenge - the Hard Enduro the offroad enthusiast.

The BMW G 650 Xchallenge proves at very first sight that it has a lot to offer: This is an uncompromising offroad machine with long spring travel and not one single gram of extra weight. In its design, the BMW G 650 Xchallenge is dominated by proportions typical of a genuine Enduro - a high-lying, but smooth and flat flyline merging directly into the high and slender rear end to offer the rider the ideal seating position. Made of fracture-proof and elastic plastic (mainly polypropylene), the fairing components both light and robust are likewise ideal for tough offroad requirements. The front wheel cover is fitted directly to the lower fork bridge, giving the front wheel superior smoothness and running freedom under all conditions. The slender fairing, in turn, gracefully takes up the asymmetrically contoured headlight featuring a reflector in free-form design.

Positioned off-centre, the parking light, finally, helps to provide that typical look of BMW Motorrad further enhanced by paintwork in Aura White and the Blue seat.

Benefiting from 270 millimetres or 10.63" spring travel both front and rear, BMW Motorrad's new Hard Enduro will easily take on any challenge off the beaten track. Tube diameter of 45 millimetres or 1.77", in turn, gives the upside-down telefork enormous overall stiffness, allowing a handlebar lock of 40°.

The springs and dampers are all specially tuned for offroad use, meeting the highest demands in every respect. As a function of his own weight and personal preferences, the truly ambitious Enduro rider is even able to fine-tune the dampers on their inbound and rebound strokes, the adjustment mechanisms offering predetermined rest points for smooth, consistent adjustment.

Again in the interest of minimum weight, the wheel axle measuring 20 millimetres or 0.79" in diameter is drilled hollow on both the front and rear wheel. The rear wheel suspension also allows various adjustments and set-ups, albeit of a very different character: Like the BMW HP2 Enduro, the BMW G 650 Xchallenge features the BMW Motorrad Air Damping System, a special spring/damper system operating exclusively with air. In its
configuration and functions, the Air Damping System is the same as on the HP2 Enduro and has merely been adjusted in terms of weight and its running requirements.

The BMW Motorrad Air Damping System comes with a piston inside, similar to the configuration in conventional spring struts. Instead of hydraulic fluid, however, this system forces out air through plate valves into a second chamber, the damping effect being achieved by throttling the flow of air.

Since gas is compressible, the air within the system can act as a kind of spring replacing the usual steel spring and thus offering the advantages already lauded on the BMW HP 2 Enduro:

  • "Natural" progression of spring rates under high load (with growing pressure within the system).
  • Reliable and smooth operation minimising the risk of the suspension giving way (physical law of gases: pressure increases as a function of temperature).
  • "Natural" progression of the damping effect under high loads (the viscosity of air increases as a function of temperature).
  • Frequency-dependent, selective damping effect.
  • Resistant to overheating (no temperature-induced weakening of the damping effect under high loads).
  • Simple option to adjust the dampers to the load carried.
  • Low weight of the entire system and its components.
  • Individual adjustment and set-up of the suspension matched to the rider's weight and the load carried by means of a water level presenting the normal position and trim of the motorcycle.

The reduction in unsprung masses also improves spring response and traction on the rear wheel. To the outside, the spring strut is sealed hermetically and is therefore protected from contamination, with any losses caused by leakage being set off by filling in air through a valve.

The system adjusts very easily and conveniently to different load conditions simply by varying the pressure filling. And to pump up the system while travelling, the rider has the option to use a hand-operated high-pressure pump fitted beneath the seat of the G 650 Xchallenge.

A feature unique to this air spring damper system is the choice of frequency-related damping achieved by varying the inner flow system together with the throttle openings. And an important effect achieved in this way is much better traction of the rear wheel on bumpy, undulating surfaces: The damping effect can be appropriately adjusted in the frequency ranges typically encountered on the rear wheel swing arm as a result of bumpy surfaces, the wheel thus following any such bumps in an ideal motion, maintaining optimum ground contact at all times. The result is even better grip and traction when accelerating all-out, as well as extra safety when applying the brakes.

Any risk of the springs sagging and giving way, as is often the case on long, undulating surfaces and under high loads, is largely excluded by "natural" adjustment of the spring rates in the air springs together with the frequency-specific damping effect: An adjustment bolt opening up a bypass in the damper enables the rider to pre-set the damper characteristics to two stages for either more comfortable riding on regular roads or for a firmer set-up on offroad terrain.

It almost goes without saying that the wheels and tyres also meet the typical requirements of offroad riding. Due to their better elasticity, spoke wheels come as standard on the BMW G 650 Xchallenge, offering all the features of lightweight technology. The wheel hubs made of aluminium are hollow-cast and are connected to the epoxy-plated aluminium rims by extra-strong wire spokes.

To build up sufficient stabilising gyro-forces also on difficult and slow trails, the G 650 Xchallenge comes with a front wheel measuring 21 inches in diameter and running as standard on a 90/90-21 tyre, while at the rear an 18-inch wheel running as standard on a 140/80-18 tyre allows the use of specialised offroad tyres whenever required.

Measuring a significant 300 millimetres or 11.81" in diameter at the front and 240 millimetres or 9.45" in diameter at the rear, the brake discs - and indeed, the entire brake system - are conceived without compromises for handling high loads. Apart from saving weight, the cross-drilled Wave brake discs on the G 650 Xchallenge have a better self-cleaning effect than conventional discs. And while the front wheel disc runs within a double-piston floating-calliper configuration, the rear disc is held tight when required by a single-piston floating calliper.

With its 15-tooth pinion and a 47-tooth sprocket, the G 650 Xchallenge has a shorter final drive ratio than the other two models in the new G 650 X model range.

BMW G 650 Xmoto - enjoying fast bends on the road.

Even at a standstill, the Street Moto clearly proves that this very special machine focuses on one highlight inparticular: sheer riding pleasure on country roads. Small 17-inch wheels, the aluminium handlebar fastened in position by extra-short mounting clamps, the front wheel cover complete with its colour-highlighted tube protectors fitted close to the tyre, as well as the headlight fairing finished in twin-tone Graphitane metallic matt and Red clearly change the proportions of this special model, giving the G 650 Xmoto an even more muscular and athletic look, even though many of the fairing components as well as the asymmetrically designed headlight are the same as on the Hard Enduro.

The Street Moto nevertheless stands out significantly from its "sister models" in terms of its suspension set-up, with the smaller cast-aluminium 17-inch wheels running on sports tyres with very good grip ensuring optimised handling in every respect. Measuring 120/70 at the front and 160/60 at the rear, the tyres reflect the muscular look and character of the machine, allowing use of the latest sports tyres on the rims measuring
3.5 and, respectively, 4.5 inches in width.

Apart from lower gyro-forces on the front wheel, the shorter camber also enhances the motorcycle's handling and agility on the road.

The forward-leaning seating position also helps to make long and winding bends as well as serpentines a truly outstanding pleasure on two wheels, optimum directional stability on straight passages in between again leaving nothing to be desired.

One of the improvements made to optimise the motorcycle's suspension geometry is the opening for the front axle moved further back, again in the interest of almost playful but nevertheless safe handling for significant benefits also in city traffic.

Both the springs and dampers are specifically tailored to the Street Moto with its particular requirements and riding qualities. While the upside-down telescopic fork offers 270 millimetres or 10.6" spring travel like on the Hard Enduro, the fork is even firmer and tauter all round in its inbound and rebound motion. Particularly the sporting rider will be happy to enjoy the sensitive, incremental adjustment of the damper in both directions, ensuring an individual, personalised set-up at all times.

Rear-wheel suspension, in turn, is firmer and shorter, with spring travel at the rear of 245 millimetres or 9.65".

The Street Moto boasts the most powerful brake system of all models in the G 650 X line-up: At the front a four-piston fixed calliper interacts with a 320-millimetre (12.60") brake disc in floating arrangement, interacting with high-grip radial tyres for exceptional deceleration benefiting in particular from the very high torsional stability of the USD telescopic fork with its main tubes measuring 45 millimetres or 1.77" in diameter.

With its 240-millimetre (9.45") brake disc and floating-calliper configuration, the rear-wheel brake is the same as on the other two models.

Final drive on the G 650 X Moto conceived for road use comes with a ratio of 16 : 47 teeth, that is somewhat "longer" than on the Enduro version.

BMW G 650 Xcountry - a modern interpretation of the scrambler.

Back in the '50s and '60s of the last century, road-going motorcycles also suitable for offroad use after making a few technical modifications were called "scramblers". And today the BMW G 650 Xcountry offers the same versatility, bringing together the best of two worlds: excellent road-going qualities combined with offroad assets typical of an Enduro.

In terms of both looks and technical features, the G 650 Xcountry stands out quite clearly from its two sister models: Featuring a smooth-lens round headlight, a "naked" cockpit without fairing, a two-level seat and the front mudguard running close to the wheel and held in position by a stable tubular bracket, the G 650 Xcountry alludes clearly and intentionally to the classic scrambler. Indeed, this particular look is further enhanced by the high-rising exhaust system as well as twin-tone paintwork in Deep Black and White Aluminium matt metallic.
The G 650 Xcountry is also quite unique in technical terms, the telescopic fork still offering ample and relatively smooth wheel travel requiring a mere 240 millimetres or 9.45" overall travel to ensure exemplary riding comfort and appropriate offroad qualities. The rear gas-pressure spring strut, in turn, comes with an adjustable inbound stroke and spring pre-tension allowing 210 millimetres or 8.27" spring travel. It also features convenient adjustment for length allowing variation of seat height from 840 to 870 millimetres
(33.1 to 34.3"). In combination with the high-rising aluminium handlebar complete with vibration-damping weights, this ensures a particularly casual and relaxed seating position.

It almost goes without saying that a scrambler, by tradition alone, simply has to come on wire-spoke wheels. So this is precisely what the G 650 Xcountry has to offer, ensuring consistent lightweight technology all the way, with hollow-cast aluminium hubs and epoxy-plated rims also made of light alloy.

Typical of a scrambler, the 19-inch front wheel, as well as the 17-inch wheel at the rear, both roll on hollow-drilled wheel shafts. And last but not least, tyres with their own special tread and dimensions of 100/90 at the front and 130/80 at the rear, again live up to all the versatile and individual requirements made of a scrambler.

Superior stopping power is provided also on the G 650 Xcountry by brake discs measuring 300 millimetres or 13.16" in diameter at the front and 240 millimetres (9.45") in diameter at the rear. The brake callipers are floating units with double-piston actuators at the front.

Featuring a 16-tooth pinion and a 47-tooth sprocket, finally, the final drive ratio is exactly the same as on the Street Moto.
