Harboline 765 is a course that debuted in Ridge Racer 6. It features good amounts of undulation due to its hilly nature, as well as tight corners and high-speed areas. Just like Midtown Parkway and Seaside Route 765, the home straight features a jumbotron.
- The jumbotron plays intro videos of older Ridge Racer titles. In Ridge Racer 6, it shows Ridge Racer (PSP)'s intro. In the following sequel, it shows Ridge Racer 2 (PSP)'s intro, whereas in Ridge Racer Slipstream, it plays Ridge Racer 3D's intro.
