Bari Bari Densetsu (バリバリ伝説) is a Japanese motorbike racing-themed manga series written and illustrated by Shuichi Shigeno. It was serialized in Kodansha's shōnen manga magazine Weekly Shōnen Magazine from 1983 to 1991, with its chapters collected in 38 tankōbon volumes.
Earlier parts of the story focus both on high school life as well as street racing. At first the characters are illegal street racers (Japanese: hashiriya) that race on public roads, particularly on the winding mountain roads known as tōge. Those kind of racers were called "rolling-zoku", a type of bōsōzoku, and were seen as a social problem in Japan. Later parts of the story revolve around professional motorcycle racing events held on road circuits like the All Japan Road Race Championship.
