There’s two things here I guess. Maybe you just want a rigged motor bike so you can do cool animation stuff with it. So in that case, the rigging part is not of much interest to you and you could just follow a YouTube video step by step. Or maybe you are most interested in learning how to rig a motor bike, in which case you’re probably better off learning from a ton of rigging courses, you with all the knowledge you can rig the bike yourself.
