Rapid Dash is an installable performance-enhancing component for Extreme Gears. Its actual appearance is unknown, though it is presented as an icon on the head-up display in the top-left corner of the game screen. Its icon is orange with the image of a person sprinting inscribed in it.
In gameplay, Rapid Dash is a customizable Gear Part that can only be attached to different Extreme Gears. It can be bought from the shop for 250 Rings.
When in use, Rapid Dash will increase the maximum speed of its Extreme Gear when the player performes a Kick Dash until the player deactivates it or finishes the race.
If Rapid Dash is installed into the front slot, it becomes active in gameplay once the race begins. If installed into the rear slot, however, the player can activate, and as well deactivate, Rapid Dash by switching stance by turning his/her body around due to the Kinect controls of the game.
