Pour une sensation de sécurité entièrement nouvelle sur la route.
Le système optionnel Dynamic ESA de BMW Motorrad est une suspension électronique qui ouvre des possibilités entièrement nouvelles tout en fournissant une sécurité de conduite et des performances maximales. La suspension semi-active, qui est utilisée pour la première fois sur la nouvelle R 1200 GS, détecte le mouvement vertical du réglage de la géométrie du train de roulement dans tous les cas en termes de distance et de vitesse via l'un des capteurs de course de ressort avant et en utilisant plusieurs des paramètres arrière, permettant ainsi d'ajuster le serrage automatiquement aux conditions déterminées quel que soit l'état de la route ou les manœuvres du pilote. L'action d'amortissement des jambes de force est ainsi adaptée à l'avant et à l'arrière via des valves de contrôle actionnées électriquement. Avec un contact nettement meilleur entre la roue et les pneus, le système Dynamic ESA communique des sensations entièrement nouvelles lors de la conduite.
Rather than functioning as a self-sufficient system, Dynamic ESA can communicate using the other control systems – BMW Motorrad ABS and Automatic Stability Control ASC. The basic settings of Dynamic ESA are also linked with the driving modes "Rain", "Road", "Dynamic", "Enduro" and "Enduro Pro", which can be simply selected by the rider at the push of a button. In every driving mode, the rider is assigned a damper setting as recommended by experts at BMW Motorrad. The rider can adapt coordination between Dynamic ESA, engine control (characteristics), ABS and ASC to the driving situation accordingly by selecting the preferred modes and hence settings. In addition the damping setting can be personalised in all modes according to the rider's wishes, from "Soft" to "Normal" or "Hard". Depending on the rider's requirements, the load is set for one person, one person with luggage or two persons.
In "Rain" mode, the spring elements operate with a soft basic setting. ASC is set in "Rain" mode for particularly early control intervention to ensure the maximum possible safety. ABS is configured to road use.
If the rider selects the "Road" mode, Dynamic ESA will have a more rigid set-up. ASC ensures optimal traction on dry roads and ABS is also configured for road use here.
In "Dynamic" mode, BMW Dynamic ESA provides an even more rigid shock absorber setting, which is entirely tailored to sporty riding during road use. With this usage profile, ASC has even more rigid characteristics and even allows for slight oversteering for experienced riders. The ABS setting is also tailored to road use here and greater dynamic throttle response from the engine at the same time.
"Enduro" has been created for off-road driving with a shock absorber setting designed for high traction. With this ASC allows more rear wheel slip so that slight oversteering is possible on rough terrain. The ABS setting is designed for riding on loose sub-surfaces such as gravel with road tyres and an accordingly high slip level. ABS operates using the partial integral function just like on roads i.e. when the front wheel brake is applied, a part of the braking force is conducted to the rear brake here too. The control strategy is designed so that blocking of the wheels is prevented yet a good level of deceleration is still attained.
Riders can access "Enduro Pro" mode designed for demanding off-road use via an additional coding plug. This enables a setting with significantly higher power reserves. In this mode, which is designed for off-road use with lugged tyres only, skilled riders can deliberately skid the rear wheel due to ASC interventions that are coordinated to professional use of Enduro. This is a special version of ABS characteristics since control is specially coordinated to riding over loose sub-surfaces with lugged tyres. Beyond this, ABS control is deactivated on the rear wheel when the rear wheel brake is applied, which also enables braking drifts before hairpin bends for instance.
