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. No other vehicles in Mario Kart Wii bear physical resemblances to its playable characters.
Bowser's Flame Runner makes a cameo appearance as a trophy in Super Smash Bros. for Wii U.
The Flame Runner has great speed with good weight, drifting and mini-turbo: it is the third fastest bike in the game, behind the Sneakster and the Spear respectively. It is the lightest large bike in the game. Its speed is tied with the Blue Falcon. 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.
On the Flame Runner, the color changes on the front wheel well and back wheel, the bike's body, and the exhaust pipe.
