Hand cast from brass or aluminum by "The Factory" using traditional casting methods. Originally designed as a knob for hand shift models, but nobody is keeping you from putting it somewhere else on your bike. These ornaments have a threaded hole at the bottom. Great vintage looks that can be combined with other cast covers from "The Factory" found elsewhere in this catalog. Ornaments are, like almost any part from "The Factory", attractively packed in a true Old Skool wooden box.
