Metal is a course of the Top Ride mode in Kirby Air Ride. It is situated within a industrial factory, similar to Machine Passage. The turnout is separated by a simple border. The players can go onto spinning cogs and a tread, making them hard to maneuver across. Near the finish line, the players can activate red, yellow, and blue switches by pressing A. This causes a fan for each switch to turn on, slowing or speeding racers. The finish line is at the bottom of the course, with a moving cog right afterwards.
With the hazards turned off, the cogs are motionless. Players are unable to activate fans.
The default amount of laps required to finish is 5.
