The Weight is a stat for Karts and Bikes. Weight is important when a collision occurs between two karts. The lighter kart will be pushed aside, often Off-Road or on a wall. It also effects the way a car drives. Normally, the heavier the kart is, the faster it will be and the slower its acceleration will be. The lighter kart would normally be slower but much better acceleration. These are the weights for all racers from all Mario Kart games.
