@Natalya: Yes, they slightly turn. But turning was sacrificed to some sort of suspension system that allows the treads to accompany the terrain, like a tank. Still, the rider can "block" the suspension for jumps and so
@Tuefish: My sig-fig is supposed to be the brutal epic rider, but Im still workin on some more badass looks and a "biker" army is already made( The Metal Warriors), Ill take pics tomorrow, also, check below my reply to Hoboman
@Hoboman: Way ahead of ya mate

The Painkiller will be the "lead" bike. Some more bikes (not this awesome but still pretty cool) are already being built for a death bike squad
