Unlikely. Is there any difference in the braking action when you're wheeling the bike about between the ignition being on and off (engine doesn't have to be running - it's an electric servo).
My Mar 02 Adv has Evo brakes, but they aren't servo assisted (or linked, or ABS). When was your's first registered?
Look at the ABS multi-slotted sensor ring on the front wheel. If it's a cast item, your bike is pre-EVO. If it's a pressed item, you have the EVO brakes.
If you haven't got ABS, look at the front caliper. If it has brembo on it, it's pre-EVO, if it has BMW, it's EVO.
Greater safety when braking, including panic brake applications.
Increased convenience for the rider.
Quicker build-up of braking pressure.
Ideal brake force distribution between the wheels.
Dynamic adaptation to load conditions, with "learning" ability.
Integral function: deceleration of both wheels by actuating only one brake lever (fully integral function) or by applying the front brake lever (partly integral function).
No danger of sliding or skidding due to locked wheels.
More braking power for the same manual effort.
They also say that the system is lighter and has no pulsing of the brake lever.
