Bridgestone Rain Kart Tires
The larger class karts have 9" or 10" pneumatic tires and weigh in between 60 and 80 pounds. They typically have water-cooled motors ranging from 40cc to 85cc, and travel in between 40 and 70 MPH. These karts are commonly used in racing organizations across the country. An example of this is the BoXer MRB line, which are built to the customer's specifications.
