Tipped Past Balance Point
Forensic Reconstruction: At pitch angles past 78.0°, the combined Center of Mass moves behind the rear axle contact patch. Gravity transitions from a restoring torque to an unrecoverable destabilizing moment. At 84.5°, the rear fender contacts asphalt, generating a catastrophic pivot strike.
