This is my description to the game "Nirin" by Namco Bandai made in 2008:
A crazy and fast-paced racing game by Namco. 5 bikes and 5 courses are to choose from. You ride your bike towards your opponent and his clones in crowded public city streets at night. Banking the bike gains boost, the key to win the game. Boost as long as you can, and don't crash into other cars to win.
