Check out the classic and antique bicycle exchange (thecabe.com)
and search Harley Davidson---HD made some way cool bikes back at the beginning of the last century. If one were lucky or rich, an old HD bike would make an awesome MB.
Harley badge engineered an Aermacchi and called it the Harley Hummer back in the 50's and 60's. 49cc's and I think 2 stroke. But anywhoo Good Luck on the project!
Harley did and still does license out their name to get slapped on somebody else's product.
More $$$ for both parties involved, and It only took a sticker!
