Then I don't understand how it works, except for ABS and ASR.... On a car the VSC is able to brake on one wheel to help the car turn, but as long as there is only one front and one back wheel this is not doable on a bike...
Tchou, I think that it has to do with controlling the bike on dirt roads. They also come with ASC and ABS integrated brakes. And my last BMW bike had the ABS but was fairly difficult to handle on dirt or gravel roads. Bike was an R1200 CLC and weighed in at about 800lbs. Took some of the fun out of driving it on dirt type roads and paths. But of course it wasn't really made for that, being as it was for touring. I just like to take side roads from time to time. And now the newest ones have the VSC and ASR also.
Eletronic stability programmes (ESP) allows the computer to brake each wheel individually in order to maintain control of the vehicle. It may be just one wheel, it might be all 4 in some order depending on the skid and the conditions, speed, steering angle etc.
When you have integrated ABS brakes, both brakes are basically applied when using either the front brake or the rear brake. Works very good on the highways and roads, but in the gravel and dirt road it was pretty hard to control slides, etc. due to the dirt shifting under each wheel differently. With the VSC it changes the ABS integrated braking into individual braking which is suppose to be much better in the dirt. If you stop by a BMW bike dealership they will probably show you on the bigger bikes. R 1200 RT is the bike I am looking at this time around. My 2003 didn't have VSC or ASC for that matter, but did have the ABS integrated. The ABS can be a real life saver but don't ask me how I know. lol
Or . . Honda on the ST1300 Kawasaki on the Concours 14 Yamaha on the FJR1300 Moto Guzzi on the Norge 1200 And even the motorcycle builder which had a long earned reputation of NOT innovating, Harley Davidson, now apparently has the most models available with ABS. http://www.harley-davidson.com/wcm/Content/Pages/2008_Motorcycles/ABS.jsp?locale=en_US It's not just a BMW thing.
