Also the motorcyclists don't have any smoke rounds, so there is no danger of them popping visibility blocking smokes when they retreat in panic after taking horrendous casualties from whatever is lurking in the woods.

That said, if you are suspecting minefields, I am not sure how likely a motorcycle unit is to trigger the mines when plowing into a minefield (infantry units in general seem to have lower probability of triggering mines when entering a unit). Thus you might maybe want to have multiple motorcycle units at the head of the column, to ensure that one of them hits the mines before the vehicles will show up.

Edit: based on a quick test, it seems that motorcycle units are quite likely to trigger mines when entering a hex with them. That said, to be sure you might want to have at least 2-3 motorcycle units at the head of the column to ensure that you find where the minefield starts.
