Sport bike (vehicle class)

Sport bikes, commonly known as inside drifting bikes or inward drifting bikes, are a class of bikes that commit to the turn instead of actually drifting. Introduced as hang-on type (「ハングオンタイプ」) bikes in Mario Kart Wii, they have become one of the four body classes in Mario Kart 8, distinguished from standard bikes.

Since they don't drift, but rather commit to the turn when the player attempts to manually drift or autodrift, they handle in a significantly different way from every other vehicle class in the Mario Kart series. In both Mario Kart Wii and Mario Kart 8, they can be distinguished from standard bikes by looking at the usually less upright and more aerodynamic posture of the character riding them.

Mario Kart Wii
Sport bikes are introduced as hang-on type (「ハングオンタイプ」) bikes in Mario Kart Wii. They are not explicitly distinguished from standard bikes in the vehicle selection screen, requiring the player to look at the posture of the rider to understand whether the selected bike is a sport bike or a standard bike.

The main distinguishing feature of sport bikes is that as soon as the player attempts to start drifting with them, they instead commit to the turn. Furthermore, when the player tries to start drifting after landing from a jump they quickly make a sharp turn toward the inside of turn and then start commiting to the turn. This latter aspect leads to them being able to take sharp turns despite their lower turning capability (angular velocity) while they commit to the turn, compared to that of karts when they drift, and results in them having in general relatively high Drift statistics in the vehicle selection screen despite said actual low turning capability, the only exception being that of Dolphin Dasher which is given a low Drift statistics despite its turning capability being actually higher than that of the Sneakster.

Like all the other bikes in the game, they are unable to charge Super Mini-Turbos, but the rider is able to perform wheelies on the player's input to temporarily increase their top speed.

Since in Battle Mode it is only possible to choose the Standard Kart and the Standard Bike, sport bikes cannot be used in Battle Mode.

When characters ride sport bikes, they usually perform the same tricks performed on standard bikes, with the exception of the medium-sized characters, whom perform unique tricks when riding sport bikes.

Mario Kart 8 / Mario Kart 8 Deluxe
Sport bikes return as one of the four body classes of Mario Kart 8, alongside karts, standard bikes, and ATVs. Like the standard bikes, in this game sport bikes are given a proper name and a distinct icon on the vehicle customization screen that allows them to be distinguished from standard bikes.

Just like in Mario Kart Wii, sport bikes commit to the turn when the player attempts to drift with them; unlike in said game, however, in Mario Kart 8 they actually turn only when they are leaning and not as soon as they land after a jump. In addition, compared to the other vehicle classes having the same Handling and Speed statistics when the player manually drifts, when the sport bikes commit to the turn as a consequence of the player attempting a manual drift they charge their Boost counter as fast as the drifting vehicles, but their turning capability is inferior while their top speed is higher. Importantly, these different properties are not applied when autodrifting, even though they still commit to the turn instead of actually drifitng.

Interestingly, even though the exploit known as fire hopping doesn't require the vehicle to drift, sport bikes are completely unable to perform said exploit. Just like with standard bikes, sport bikes are able to charge Super Mini-Turbos but their riders are no longer able to perform wheelies on the player's input, as they perform them only during certain boosts. Sport bkes are also given unique statistics not shared with bodies pertaining to other vehicle classes, leading to them having strong Handling statistics, with the non-DLC sport bikes having the highest Handling and the lowest Traction statistics in the game, possibly compensating for their lower turning capability when the player attempts a manual drift.

When riding sport bikes, the characters perform the same tricks they perform on standard bikes, with the sole exception of Larry, Princess Peach, and Baby Daisy, whom perform a different trick while riding them (the secondary trick in the case of Larry and Princess Peach, and the anti-gravity trick in the case of Baby Daisy). In addition, only two CPU-controlled characters are able to ride sport bikes: Mario, who can ride on his Comet, and Link, who can ride on his Master Cycle.

In Mario Kart 8 Deluxe, sport bikes are able to charge Ultra Mini-Turbos like the other vehicle classes, but they no longer have unique statistics not shared with bodies of other classes, as well as the best Handling and worst Traction in the game. Furthermore, more CPU-controlled characters are now able to ride sport bikes.
