Try searching for motorcycle blueprints.
http://www.the-blueprints.com/blueprints/motorcycles/
I user this site quite often for creating 3d models of bikes, cars,etc...
Hope this helps.
I use a site called http://www.cad-architect.net for all my technical dwg needs. They are more based towards architects & architectural templates & symbols, but also have various useful engineering dwg's. I also know they have symbols of motorcycles. Good luck, hope this helps....
(Where can I find this kind of dwg files?Thanks for help..
