Hang-On

is a 1985 racing video game developed and published by Sega for arcades. In the game, the player controls a motorcycle against time and other computer-controlled bikes. It was one of the first arcade games to use 16-bit graphics and uses the Super Scaler arcade system board, created with design input from Yu Suzuki, as technology to simulate 3D effects. The deluxe cabinet version also introduced a motion-controlled arcade cabinet, where the player's body movement on a large motorbike-shaped cabinet corresponds with the player character's movements on screen.

Yu Suzuki began development of Hang-On after deciding to design a motorcycle racing game as a way to use a torsion bar in an arcade game. With market research suggesting GP 500 racing was popular, Suzuki took inspiration from world champion Freddie Spencer and his style of racing. The game's soundtrack was written by Hiroshi Kawaguchi, who used rock music that was uncommon in arcade games at the time. Following its initial release for arcades, Hang-On was ported to Sega's Master System and SG-1000 consoles, as well as to the MSX and PC-88 computers.
