For generations of motorcyclists, BMW Motorrad has been regarded as a leader in terms of motorcycling safety. With its innovative strength, BMW Motorrad established its profile as a trendsetter early on in this field and today the huge safety benefits it offers are a persuasive selling point for virtually all motorcyclists. BMW Motorrad research continues to work on increasing these safety benefits, thus making motorcycling even more attractive.

BMW Motorrad – a pioneer in the field of safety for decades.
BMW Motorrad was one of the first two-wheel vehicle manufacturers to commit proactively to motorcycle safety back in the 1970s. This dedication to increased safety began in 1976 with the motorcycle helmet developed by BMW Motorrad. Other highlights followed in 1986 with an in-house range of rider equipment and in 1988 with the world’s first ever motorcycle ABS. Since 2005 a number of other elements have supplemented active safety in BMW motorcycles: tyre pressure control, the traction control system ASC and a xenon low-beam headlight. In the area of rider equipment, the NP protectors developed by BMW Motorrad for motorcycle suits contribute to passive safety, as does the new generation of helmets and the Neck Brace System introduced in 2007.
Today, ABS is either a standard feature or an ex-works option throughout the entire BMW Motorrad range. In the case of the BMW S 1000 RR the system was refined in 2009 to create the Race ABS so as to meet the needs of supersports riders, thereby achieving a new climax in terms of technological advancement.
At the same time, BMW Motorrad presented the Dynamic Traction Control System (DTC), an extension of the BMW Motorrad Automatic Stability Control (ASC). For the first time ever in serial motorcycle construction, DTC incorporates the banking angle of the motorcycle as an additional parameter. This allows the traction control system to stabilise the motorcycle with even greater sensitivity, especially when taking bends.
BMW K 1600 GT/GTL – extensive safety features now as standard.
Today the two BMW luxury touring bikes K 1600 GT and K 1600 GTL are fitted with numerous safety features, either as standard or as optional extras ex works.
For example, the brake system meets the highest possible standards in terms of deceleration, controllability, stability and control response in conjunction with ABS. The three modes “Rain”, “Road” and “Dynamic” allow the rider to select three completely different engine characteristics in terms of throttle response and torque availability. In conjunction with DTC (Dynamic Traction Control) this results in significantly improved traction based on controlled engine power and traction control, especially on wet or slippery road surfaces.
With regard to chassis technology, the electronically adjustable chassis ESA II optimises the adjustment of suspension and damping to load and road surface conditions. The neutralisation of load states in particular makes for a further increase in ride and braking stability.
In addition to ABS, DTC and engine characteristics which the rider can select, the K 1600 GT/GTL are the first serial production motorcycles in the world to offer an adaptive headlight (option ex works). Here, detection of the banking angle and pitch movements of the vehicle achieves much improved illumination of the road on bends, resulting in a huge increase in active riding safety. The K 1600 GT/GTL are also the first motorcycles to feature the so-called parking light rings which are characteristic of BMW automobiles.
BMW Motorrad Advanced Safety Concept – Daytime Riding Light as a safety innovation in motorcycles.
Seeing and being seen is especially important on a motorcycle. For this reason, the LED parking light technology of the two lighting rings which was standard in the BMW K 1600 GT was further refined for the Advanced Safety Concept constructed on the basis of the BMW K 1600 GT to demonstrate the technological possibilities of Daytime Riding Light, approved for use in motorcycles since 2010.
Here the light intensity injected in the lighting rings was significantly enhanced so to ensure that the motorcycle can be detected early on and more clearly by oncoming traffic – a technological innovation which might quickly find its way into serial production.
BMW Motorrad eCall with automatic collision notification ACN as a life-saving system.
If a serious accident occurs, seconds can be crucial. Very often valuable time is lost because the rescue coordination centre is informed too late or too ambiguously about the location and severity of the accident. This is where the BMW Motorrad eCall / ACN (Emergency Call / Automatic Collision Notification) provides a valuable service.This system is already available as a standard feature in BMW automobiles and a solution specific to motorcycles is currently being worked on. This could even be incorporated in serial motorcycle production in the medium term.
If the rider arrives at an accident site on a bike fitted with BMW Motorrad eCall, he can use the eCall button to trigger a manual emergency call. The accident details and exact location with GPS data are then transmitted to a BMW Call Center which passes on the information as necessary to the nearest rescue coordination centre.
If the rider of a BMW motorcycle fitted with eCall is involved in an accident himself, this is registered by means of the sensor system (ACN) and an automatic emergency call is triggered. This automatically establishes a connection with the BMW Call Center, enabling transmission of the required data, such as location and more detailed information on the nature of the accident.
Camera-based BMW Motorrad rider information and assistance system.
As part of another research project, work is currently being done on a motorcycle-specific adaptation of a camera-based rider information and assistance system which could be ready for serial production in the near future. This system can actively contribute to preventing dangerous situations from arising in the first place.
The Advanced Safety Concept based on the BMW K 1600 GT is fitted with a camera-based rider information system to monitor the environment. The system provides feedback on speed limits (Speed Limit Info) by means of road sign detection and graphic display on the instrument panel.
The camera is also capable of detecting objects, thereby enabling automatic detection of obstacles on the road, for example. A warning is given if there is a risk of collision. For the first time in a motorcycle, the system actively detects danger and is capable of triggering secondary measures. These include generating a visual signal which draws the motorcyclist’s attention to the object detected, for example, and also preparing the brake system for imminent intervention
At the same time, the motorcycle enhances its visibility so as to provide a warning. If there is a risk of collision, the headlight beam is modulated, the intensity of the headlight is enhanced and the LEDs integrated in the mirrors and turn indicators are activated so as to widen the motorcycle’s silhouette.
BMW Motorrad ConnectedRide with intelligent assistance systems.
Research areas in the field of vehicle-to-vehicle communication show that a long-term approach is also being adapted to motorcycle safety.
ConnectedRide – a research project being run by BMW Motorrad and BMW Group Research and Technology – indicates developments which could advance safety much further. Assistance systems based on vehicle-to-vehicle communication make motorcycling much safer still: these are to be installed in serial production motorcycles by BMW Motorrad in the future. In connection with this research work, BMW Motorrad is the only motorcycle manufacturer involved in a large-scale field test with five vehicles.
BMW Motorrad already presented six elements of the ConnectedRide program in June 2009 at the International Technical Conference on the Enhanced Safety of Vehicles” or ESV in Stuttgart. In addition to the cross traffic and traffic light phase assistant, BMW developers designed three warning systems especially for motorcyclists: for bad weather conditions, obstacles and approaching emergency vehicles.
The fourth system to be presented by BMW Motorrad was the draft for an electronic brake light which responds to sudden brake manoeuvres in dense traffic lines, automatically relaying the information to the rear in a fraction of a second.
An additional assistance system was presented in May 2011, the left turn assistant, along with the most recent stage of development in this area: the overtaking assistant.
The cross traffic assistant analyses road users approaching a junction, the priority situation and the probability of a collision as well as assessing the response of car drivers required to wait. A display in the cockpit indicates the traffic regulations to the car driver – for example in the case of a potential failure to give way. If the driver does not respond appropriately, he is warned of the risk of collision in stages – in visual, tactile and acoustic form. On the motorcycle, the road light is gradually modulated, light intensity is increased and additional LED strobes at the side of the motorcycle are activated so as to widen the silhouette and thereby increase notice ability in the case of an increasing risk of collision. If a collision is imminent the motorcycle horn is sounded automatically.
The traffic light phase assistant allows the traffic light system to communicate with the motorcycle. If the traffic lights are set to red when the motorcycle arrives at the intersection at an unchanged speed, the rider would receive this information early enough via the instrument panel to be able to brake gently. The assistant is also able to display a speed at which he could reach the traffic lights during the green cycle.
The bad weather warning gives the motorcyclists a visual indication in the instrument panel – optionally also a voice message in the BMW Motorrad Communication System – to provide early warning of a route section with weather conditions such as fog, rain, snow or black ice. The assistant also gives details of approximately when the rider can be expected to encounter these conditions. As the trigger algorithm, researchers have in mind a certain number of vehicles switching on their fog lamps for example. This information, combined with the exterior temperature of the vehicles in question, can be used to infer snow or hail. Other sources of data include rain sensors, regulatory systems such as DSC and rear fog lamps switched on.
The obstacle warning also indicates to the motorcyclist by means of a visual signal in the instrument panel – also with optional voice message – that an obstacle is to be expected on the road. This might be oil or chippings on the road, or a broken-down vehicle at the roadside. The warning also includes details of approximately how far away the obstacle is. The warning and location of the danger could be transmitted by the vehicle or vehicles ahead to the vehicles behind.
The emergency vehicle warning system provides a visual display in the instrument panel which gives the rider early indication of an approaching emergency vehicle. A clear symbol and a voice message warn the rider, also providing details of the distance.
The idea behind the electronic brake light is the fact that the brake lights of a vehicle subjected to sudden heavy braking may possibly be hidden by the vehicles behind it. These results in a delayed reaction which can cause rear-end collisions. In order to inform traffic to the rear as early as possible that a brake manoeuvre has been carried out, this information is communicated to other road users by means of vehicle-to-vehicle communication as part of the electronic brake light system. The latter receive this information via the instrument panel and communication system.
An additional left turn assistant takes into account the particular risk potential of this traffic situation to the motorcyclist. Additional LEDs in the rear mirror casings and automatic high beam activation make the motor-cycles more visible to traffic turning off to the left. Calculation of the collision risk is based on data transmitted by vehicle-to-vehicle communication. If there is an acute risk of collision, simultaneous and automatic brake intervention in the car prevents it from turning off to the left.
The overtaking assistant makes an overtaking motorcycle more easily visible to other road users. The manoeuvre is detected by the system of sensors already in serial production in conjunction with Race ABS and DTC. If the vehicle ahead moves out to overtake at the same time as the motor-cycle because the driver has overlooked the motorcyclist or wrongly estimated his speed, the motorcyclist is in danger. Additional LEDs in the turn indicator are used to intensify the signalling effect, making the motor-cycle more visible within the car driver’s peripheral field of vision. This significantly increases the probability of the driver noticing the motorcycle before it disappears into the blind spot.
