Cornering UP is a Gear Part that appears in Sonic Free Riders. It is an Extreme Gear component that increases the turning abilities of Extreme Gear.
Cornering UP 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 a dark green-colored circle with the image of a lighter green curved arrow with some flames on its outer curve inscribed in it.
In gameplay, Cornering UP is a customizable Gear Part that can be attached to different Extreme Gears. It can be bought from the shop for 250 Rings.
When in use, Cornering UP will significantly increase an Extreme Gear's Turn attribute. This will improve the player's turning ability on the Extreme Gear he/she is currently using, allowing the player to make sharper turns when moving to the sides. This is very useful when encountering tight corners.
If Cornering UP 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, Cornering UP by switching stance by turning his/her body around due to the Kinect controls of the game.
