The Mach Bike is a medium weight bike that debuted in Mario Kart Wii. It resembles a superbike usually seen in motor racing. The MK8 bike counterpart is The Sport Bike.
The Mach Bike is a fast bike with the highest drift and mini-turbo stats in the game for medium bikes. It is not really as fast as the Flame Runner but the outstanding Mini-Turbos boost and help make up for this. It has world records for tracks that need a lot of drift or rely more on the mini-turbo stat than the speed stat, such as SNES Mario Circuit 3. Commonly found on Time Trials and even in normal races, it is one of the most used bikes in this game, alongside the Flame Runner.
