I have a decent quality of the MTO highway & sign quality 3M reflective material if you're looking for something unique. It's thick, it's not very flexible so it won't mold to angles or anything easily like regular thin vinyl does so it's best suited to flat or only slightly and smoothly bent pieces (tank or fairing probably ok), but if it's unique and flashy you're looking for...well, that it is.
It's all small pieces, off cuts for the most part from one of my customers that has a large regional road sign contract. The stuff is CRAZY expensive.
And you'll be able to find your bike 5 KM away in the middle of the night by reflection alone with just a pen-light.
I also have a small vinyl cutter that can do the basics but is limited in size to about 7-8" tall and about 12" long.
