The Flame Runner is a heavy-weight bike, therefore it can only be used by heavy characters. It's a Bowser themed bike, and one of the three best ones for time trials, although it's not very good for Grand Prix because of its poor acceleration. This bike is one of the three great time trial vehicles: Bullet Bike (small), Mach Bike (medium) and Flame Runner (large). It is considered the best bike in the game, especially when paired up with Funky Kong
It is also called the Bowser Bike in places other than America.
