Missions are a gameplay feature in Sonic Riders. They are a set of single-lap races performed on the different courses available within the game, but with different rules than in a Normal Race or Story Mode. They are divided into schedules by the three members of the Babylon Rogues: Storm's missions are available after completing the Heroes Story, Wave's missions are available after completing the first stage of the Babylon Story, and Jet's missions become available after unlocking Sega Carnival and Sega Illusion and completing all of the missions in Wave and Storm's schedules.
The player will receive an Emblem for completing a mission, which can be bronze, silver, or gold. Completing all missions in the game on at least bronze will unlock the characters AiAi, NiGHTS, and Ulala as well as their respective Gears, BANANA, Night Sky, and Channel5. Obtaining gold emblems on all missions will additionally unlock the Chaos Emerald Extreme Gear, plus it will add the Extreme Gears Opa Opa, The Crazy, Hang-On, and Super Hang-On to the shop.
There are a total of 100 missions the player can complete: 40 are available in Storm's schedule on the courses in the Heroes Story plus Digital Dimension and Sega Carnival, 40 are available in Wave's schedule on the courses in the Babylon Story plus Sega Illusion, and 20 are available in Jet's schedule on all the courses available in Normal Race mode.
