Bar-end plugs are more important than many would initially think. In the event of a crash, bar-end plugs make it much more difficult for the handlebars to pierce your skin (e.g. potentially the difference between getting a bruise vs a chunk of your skin being taken out!). They also protect the end of your handlebars when they take a hit. Day-to-day, they prevent dirt & other particles from entering your handlebars.
