The new BMW Motorrad Automatic Stability Control (ASC) The range of active safety systems and the systematic further development of these systems make a substantial contribution to BMW Motorrad’s market success. With this in mind, BMW Motorrad considers itself obliged, concurrent with the ongoing model campaign and a range of vehicles with enhanced dynamism, to also offer the market an all new BMW Motorrad ASC (Automatic Stability Control).

BMW Motorrad is currently the only manufacturer to offer ASC for motorcycles as an addition to Integral ABS. This is yet another example of BMW’s lead in motorcycle safety and innovation. ASC is an available option for 2007 models.

The ASC supports the BMW rider on roads with varying and lower friction coefficients. It is particularly attractive on roads where the road surface and condition for tire adhesion usually vary – a fact that every motorcyclist is aware of. Depending on the road condition, the ASC will limit the drive torque transferred by the engine within physical limits, to where an uncontrolled spinning of the rear wheel will largely be prevented. Apart from the considerable safety gain, this also means a more efficient use of the power that arrives at the rear wheel – since the ASC will only make available as much power as the rear wheel will be capable of putting on the road.

The ASC control works as follows: the ASC uses the signals of the ABS wheel speed sensors and evaluates these signals. The current wheel slip is then determined on the basis of the speed difference between the front and rear wheel. In order to allow for an improvement of the directional stability, the wheel slip will then be limited to an acceptable level. This is achieved by the engine management that retards the ignition or suppresses individual injections if a higher level of control is required.

The ASC control mode will be indicated by a rapidly flashing ASC warning light. If the intervention of the electronic system is not wanted, the system may easily be deactivated by a simple push of the button – while riding.

The ASC system – similar to all electronic systems used by BMW Motorrad – features a self-diagnosis capability, which means that the rider will be informed immediately, should the ASC function not be available.

A special off-road setup has additionally been developed for off-road use, specifically for the R 1200 GS and R 1200 GS Adventure. This setup is adapted to the specific slip situation encountered on loose ground, such as sand or gravel. A push of the ASC button shifts the system from the on-road to the off-road mode. In off-road mode it is unsuitable for on-road riding.

Benefits of the BMW Motorrad ASC
  • Largely prevents uncontrolled spinning of the rear wheel
  • Provides support for the rider by maintaining the directional stability
  • Only puts as much power on the road as the rear wheel will be capable of transmitting
  • Additional safety on roads with lower friction coefficients
  • Specific off-road setup for the R 1200 GS and R 1200 GS Adventure
  • The ASC may be activated / deactivated while riding
The ASC provides additional safety in critical riding situations as a result of unforeseeable road conditions.

Nice! So the 2007's should be shipping by Fall.

Does this mean the '07 LT will be able to handle 200 hp? :)

I wonder if BMW has investigated front wheel drive? Apparently, the hydraulic system developed by Yamaha works best for off-road bikes and large tourers.

So, disrespectfully said, they've re-invented the traction control. Hando already had that on the ST1100 Pan European last century.

Who needs TCS anyway?

Yes, I've heard of those Hando's. Aren't they imported by the same people that import Ural Russian M/C's?

I had no idea that they were so advanced!
