Use of the Harley davidson logo?

I am working on designing some reptile haesses for reptiles such as bearded dragons, monitors, iguanas and more. The design includes a piece of leather across the back and I am working on coming up with some embellishments. I was thinking about picking up some small Harley Davidson logo iron ons. Would this be a violition of their copyright?

What if I include a notice when I send them out that Harley Davidson logo is a trademark of Harley Davidson? WordPress ...
