He has to stat lines.
One when his on the bike. Here he follows the normal rules for an IC on a bike, and yes he has 3 wounds;)
The other one is when he is on his speeder. Here he follows the normal rules for a vehicle. So when you roll destroyed on the damage table he is destroyed. He doesn't have 3 wounds here. He doesn't have attacks either. Its important that you don't mix the rules;)
