i know it has already been made two Motorcycle mods but i wanted too do one by myself i stole some ideas from Playerid666 and i changed the axis of some joints and it works real good for running over Uke, under maybe any way here it is.i couldent upload the pics becuase they were too big?! Anyway
you should do like this if you want it too look like a MC, extend both ankles, extend both hips, extend the abs, bend the lumbar right, and rotate the chest left. dosent look good yet try again check everything ok let´s continue
extend both elbows and knees, ok now you should be in the air wait til your feet has almost touched the ground and then contract your wrists
