Bakuon is an anime about girls who motorcycle. However, do note that it's not an anime about the motorcycles themselves. Nor is it an anime about the girls who just so happen to be in a motorcycle club. In other words, somehow Bakuon manages to do the specificity of "girls spending their time in an interests club in school" perfectly, striking the optimal balance between technical/mechanical details and character analysis.
Seriously, who the fuck would have thought such a thing can exist?
