Go karts are the open, four-wheeled vehicles used in kart racing. They have small wheels made of aluminum or magnesium alloy and frames made of steel. They have open seats that allow drivers to sit near just a few inches off the ground. They are built for sprint, endurance, and speedway racing on karting tracks or off-road sites. Go karts are available in standard, off road, and electric models. They are powered by batteries.
