3M vinyl number plate background works great. You can buy a couple of sheets in a pack from your local dirt bike dealership for around $20 in whatever color you prefer. I chose black to match my bike. I then used heavy card stock paper to make templates and traced them onto the vinyl before cutting them out. Wrapped the lower forks as you describe, as well as the sides of the bikes frame and also the top of the upper fork tree. Looks really trick, protects from scratches, and people ask all the time where I bought them.
