In most European cities, motorcycle theft is so endemic that a shiny new bike becomes a liability rather than a pleasure. Owners sometimes resort to rattle canning a brand new motorcycle matte black, pouring yogurt all over it, or even taking a rubber mallet to the bodywork — all in an effort to make their pride and joy less desirable to thieves. These fake rust stickers should accomplish the same goal, with the added benefit of being easily removable should you ever want a bike you can be proud of.
