DEAN: I got an ’86 Suzuki.
Suzuki is a Japanese company which makes a variety of vehicles, including motorcycles. The motorycles they released during the 1980s were smaller and lighter models, designed to appeal to the American market, but with still quite powerful engines for their size.
This is the final confirmation that Dean definitely does have a motorcycle, as Lorelai intuitively knew from the beginning, despite Dean’s protestations. It seems that the Gilmore girls really do love a man on a motorbike.
