Weight is a stat for Drivers, Karts, and Bikes. Weight directly affects the results of collisions between two racers. The lighter of the two racers will be shoved aside, sometimes being shoved off the track. On maps lacking barriers like Rainbow Road and Yoshi Valley, weight can be a huge factor in taking down the competition, especially when adding in an element of speed, which can amplify this. Additionally, lighter racers have a tougher time, jostling heavier racers successfully.
In most games, weight is usually associated with the heavy racers, making it rare for high weight and high acceleration to be combined, but common for high weight and high speed to be combined.
