May receives an invitation for the Chrysanthemum Contest from someone she suspects to be Drew.
Harley defeats May in the final round, earning the Wisteria Ribbon, his fourth Kanto Ribbon. In the process, May suffers her first loss in the Kanto region, as well as her first loss to Harley.
This episode's title may come from a reference to a Harley-Davidson motorbike. It could also possibly be a reference to the comedy film Herbie Rides Again (1974).
Harley is revealed to have earned three Kanto Ribbons and own an Octillery.
May learns from Lilian that the next Pokémon Contest will be held on Chrysanthemum Island.
