Flame Runner

The Flame Runner (known as the Bowser Bike in the British English version) is a large-sized bike which appears in the game Mario Kart Wii. As the British English name suggests, the bike resembles Bowser; the coloring of the bike even mirrors Bowser himself. Its general shape also resembles a. The emblem is located on the sides of the bike. No other vehicles in Mario Kart Wii bear physical resemblances to its playable characters. The Japanese name of the bike, Super Bowser, uses Bowser's English name instead of using his Japanese name of Koopa. This was later used with the DLC Bone Rattler from Mario Kart 8.

The kart counterpart for this bike is the Flame Flyer. Its rough medium and small counterparts are the Mach Bike and Bullet Bike respectively.

Mario Kart Wii
The Flame Runner has great speed with good weight, drifting and mini-turbo. It is the second lightest large bike in the game. Its speed is tied with the Blue Falcon, and it is the third fastest bike in the game, behind the Sneakster and the Spear. It is moderately heavy, having its weight tied with the Standard Bike L. However, the bike suffers from the worst acceleration among all bikes in the game, and its handling and off-road (tied with the Sprinter) are also rather low. The Flame Runner is also Funky Kong's signature vehicle, which is used for a number of world records.

The Flame Runner is one of seven vehicles in Mario Kart Wii to go through a design change other than a palette-swap; the others being the Booster Seat, Bit Bike, Wario Bike, Shooting Star, Spear, and Phantom. In this case, Bowser's and Dry Bowser's Flame Runner have their exhaust pipes positioned lower than the other bikes. Also, Rosalina's and Female Mii’s Flame Runner feature shorter handlebars than the other Flame Runners.
