In SPWW2, you have a "motorcycle squad" of ~6 men that is a normal infantry unit and then a "MotorcycleX3" that can carry 6 men and move 30. They are also lightly armed with a SMG and handgernades. Just load them up like any other unit.
Speaking of which, Don, am I to assume that the MotorcycleX3 is coaded as a viechle?
Harlikwin, you can download SPWW2 off of the Shrapnel Games website here -

Well worth it in my opinion.
