by Armani Turcotte MD Published 3 years ago Updated 2 years ago

Small go karts can often beat the bigger karts because of their lightweight frames and also because they usually carry a lightweight driver. These two things allow a small go kart, with a smaller engine to beat a bigger go kart with a bigger engine because the power to weight ratio may be better for speed in the small go karts.
