With the optional Dynamic ESA, BMW Motorrad offers an electronic suspension which taps into a whole new range of possibilities as well as providing maximum riding safety and performance. This semiactive suspension monitors the vertical movement of front and rear wheel control in travel and speed as well as other parameters by means of a spring travel sensor in each position and adapts the damping automatically to the situation depending on riding conditions and the manoeuvres being carried out by the rider. Damping adjustment of the spring struts at front and rear is effected by means of electrically controlled regulation valves. The drastically improved contact between road and tyres means that Dynamic ESA can provide a previously unequalled sense of security.

Dynamic ESA does not work as a self-contained system, but is able to communicate with the other control systems – BMW Motorrad ABS as well as Automatic Stability Control ASC. What is more, the basic settings of Dynamic ESA are linked to the riding modes “Rain”, “Road”, “Dynamic”, “Enduro” and “Enduro Pro”, which can be conveniently selected by the rider at the press of a button. Each of the riding modes gives the rider a damper setting as recommended by BMW Motorrad experts. The driver can coordinate Dynamic ESA, engine control (characteristics), ABS and ASC to the given situation by selecting the various modes with their respective settings. What is more, the damper setting can be tailored to personal preferences in all modes, ranging from “soft” to “normal” and “hard”. Depending on the rider's preferences, the load settings for one person, one person with luggage or two persons.

In “Rain” mode, the spring elements have a soft basic set-up. In order to ensure maximum safety when accelerating, ASC is set for early control intervention in “Rain” mode. ABS is configured for use on the road.

If the rider selects “Road” mode, Dynamic ESA shifts to a tighter setup. ASC ensures optimum traction on dry roads and the ABS is also configured for road use.

In “Dynamic” mode, Dynamic ESA provides an even tighter damper setting which is entirely geared towards a sporty style of riding on the road. In this profile, ASC characteristics are further tightened, even enabling experienced riders to perform light drifts. Here again the ABS setting is geared towards road use, while also providing a more dynamic throttle response.
The “Enduro” mode provides a high-traction damper setting for off-road riding. Here ASC provides for more slip on the rear wheel, allowing light off-road drifts. The ABS setting is designed for running over loose surfaces such as gravel with road tyres, which have a higher approved level of slip. As on the road, the ABS operates with a part integral function: in other words when the front wheel brake is activated, part of the brake force is directed to the rear wheel. The control strategy is designed so that wheel lock is prevented while still allowing effective deceleration.

An additional coded plug enables the rider to access the “Enduro Pro” mode for more ambitious off-road riding. This setting provides significantly increased bottom-out reserves. In this mode – reserved solely for off-road use with studded tyres – experienced motorcyclists can deliberately make the rear wheel break out due to much reduced ASC intervention adjusted to professional endure use. The ABS characteristics are specially adapted to this situation, since control is specifically geared towards riding on loose surfaces with studded tyres. What is more, ABS does not act on the rear wheel when the rear brake is applied.
