Found some stuff on the net (if you are law enforcement I didn't). Some 3d bike models and a digital tutors lesson on bike modeling, a Ducati Monster. I have tried to do some my self, the classic Ducati Sports model (I love old school café shit) but unfortunately I suck at 3d max. I'm not suggesting that you "steal" the models right off, but they might help in some way... maybe. It's a gift, take it or leave it.
