Overbanked Turn

An overbanked turn (or overbank) is a curve where the track banking exceeds 90 degrees — the outside rail rises above vertical, putting riders past the inverted position without completing a full 360-degree rotation. Riders are briefly tilted past upside-down, experiencing a mix of lateral G-forces and mild negative G at the peak of the banking, before the track returns to a normal orientation. It is technically not a full inversion because the rotation does not complete — but it looks dramatic from the outside and produces a distinctive visual and sensory experience.

Overbanked turns are a signature element of modern B&M hypers and Intamin mega coasters, and are ubiquitous in RMC hybrid layouts where they often appear in rapid succession with airtime hills and inversions. They are frequently confused with full inversions by casual observers because the banking looks so extreme, but the sensation for riders is notably different — lateral and slightly negative rather than the sustained full-inversion experience of a loop or zero-G roll.
