Daredevil rides motorcycle on roller-coaster track

MEXICO CITY, Dec. 8 (UPI) -- A French stunt motorcyclist took on the "sickest" ride of his career when he rode his bike and performed stunts on a Mexico City roller-coaster track.

Julien Dupont, 34, who specializes in performing trick routines in urban settings, performed two back-flips during his ride on the tracks of the Montana Rusa roller coaster at the La Feria de Chapultepec amusement park in Mexico City.

The 108-foot-tall wooden coaster, which was once the world's tallest, is designed for a powerless train to travel its tracks using only the power of gravity.

"Now I feel better, for sure," Dupont said after completing his stunt. "This morning, I was very nervous because I'm not used to riding this kind of stuff. It was the sickest ride ever!"
