BNW has really elevated their electronic gizmos. Most people are acquainted with the "just don't let the wheel stop spinning" electronics which I call the first generation. BMW says there is ESA (electronic suspension adjustment) the basically sets the settings on otherwise normal suspension. Basically, this involves a stepper motor that can adjust the compression, rebound, and preload based on algorithms established in a control unit. So when you select a dynamic mode for the power, the suspension settings are firmed up.
BMW has moved to level 2 electronics. The adjustments on the suspension are active, meaning it looks at travel and a few other parameters thousands of times a second and makes fine adjustments to keep the suspension stroking in its optimum range. There are a few manufacturers out there doing this, and I don't believe the suspension on the 1250 GS is active, it's only electronic.
I was researching this and how to retrofit it to my Ohlins (active) and came across this:
GRIPONE E-SUSPENSION - Not sure I would do this but it's interesting. Seems all of this stuff would work best if it was talking to each other (TC, ABS, Active suspension) so I was hesitant to get into this.
So do you need this level of complexity on the street? I say no to active but ESA os awesome on the street. If you were a track junkie the smart suspension would be very useful.
PS: there was a second phase to my build on the Busa. It included 235 HP (all motor), TC, Wheelie, QS and maybe even this). I sort of lost interest after the frustration of dealing with vendors on the first phase as well as not having the time to spend in the garage. But who knows, maybe one day I'll get back on it.
