In Harley-Davidson & L.A. Riders, the player rides one of five Harley-Davidson models. The objective is to complete a series of checkpoints around Los Angeles under a time limit. The objective is similar to the later Sega arcade game, "Crazy Taxi" (1999).
There are five playable bike models in the game:
FLSTF Fat Boy
FL 1948 Panhead
FXDWG Dyna Wide Glide
Sportster 1200 Sport
FXRP Police Motorcycle
User note- Deluxe Arcade machines featured a miniature Fat Boy that was used as the controller.
