Motorcycle/bike inf question/weirdness

[gila]

I think Bicycle/motor should be easier io suppress and kill.
If you think about it leg units in battle usally have thier arms in hand, do bike/motorcycles?
Yes the sidecar can carry a mmg but cannot fully traverse and with the driver on board cant fire on that side.
Also, on the other side of the coin (in a arty hit), would they be able to pick-up their mangled bikes and still all units move at full speed?
