Sneakster

The Sneakster (known as Nitrocycle in Europe and Oceania) is a medium-sized bike in Mario Kart Wii. It looks similar to a stretched-out old Harley. The character's emblem is located at the very back of the bike. It is unlocked by getting a one-star rank or better on all 100cc Wii Grand Prix cups. Its kart counterpart is the Sprinter. In addition, it is also similar to the Spear, in which both are the fastest bike in their respective classes. Its engine sound is actually that of the DS Standard Kart, thus hinting this bike is a four-stroker.

Stats
The Sneakster is the fastest medium bike in the game, tying with the Flame Flyer, a heavyweight kart. It also has average weight (tied with the Super Blooper) and drift, but is actually the second heaviest medium bike in the game. Its other stats are quite low and its acceleration is equivalent to that of the Shooting Star, Mini Beast, and Piranha Prowler. Its off-road stat is tied with the Honeycoupe and the Wild Wing.

Trading Card info
"If you take a look at the Sneakster's stats you'll notice one thing: awesome top Speed. It's one of the fastest in the game. Naturally, that Speed comes at a high cost, as all other categories have far lower stats..."
