Nothing crucial. If they didn't change the gaps of sensors, which is a separate job, then everything is the same as it was, independent from wheel or tyre changes.
Just in case always test the ABS system tho after the wheels have been taken off and then put on: on slippy road surface like gravel (i.e. aside the road if you can't find one) on slow safe speeds (i.e. 10-15km/h) in safe off the traffic conditions temporarely (quickly release too after the wheels are blocked) try to push rear brake to max and then front brake, or together if you're experienced enough. You should hear and feel ABS modulators kicking in and making audible sound. Try with rear brake first, you can easily push it to max on a straight road with slow speeds, even on a tarmac road it's safe. If ABS doesn't let the wheels to block, then all works as supposed to.
Use caution with the front brake tho, only on a straight (presumably slippy, like gravel or a wet road, otherwise the rear end can rise up if the road has a good grip - circa 70+% of the bike's braking power comes from the front wheel!) road and never while turning the bike, especially if you're newbie in this!
Ride safe, Margus
