Spear

The Spear (known as Torpedo in the British English version) is a large-sized bike in Mario Kart Wii. It looks similar to a torpedo or a blimp converted into a bike with an engine and exhaust pipes. The character's emblem is located on the front and sides of the bike. The Spear 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, Flame Runner, Wario Bike, Shooting Star, and Phantom. In this case, Bowser's and Dry Bowser's Spear have their exhaust pipes positioned lower than the others. Also, Rosalina's and the Female Mii's Spear feature shorter handlebars.

Its kart counterpart is the Jetsetter. The Spear can be unlocked by unlocking 12 expert staff ghosts or by playing 3,600 races.

Stats
The Spear is the fastest bike in the game, and it also has good weight (which is tied with the Jetsetter). However, all its other stats are quite low. It shares the same drift stat as the Zip Zip and the Tiny Titan, but suffers from the worst handling, off-road, and Mini-Turbo among all bikes and its off-road is equivalent to the Flame Flyer's off-road. It is also the second heaviest bike in the game, after the Wario Bike, and it is the second fastest vehicle in the game, only behind its kart counterpart, the Jetsetter. While the visual graph shows the Spear with the same acceleration stat as the Mach Bike, its internal data shows it actually accelerates more slowly. Additionally, it has the second worst acceleration among all bikes, only being better than that of the Flame Runner’s.
