Go-karts aren''t cheap; models cost between $700 and $1,200, which buys a well-made machine with performance and safety features. In conjunction with the Consumer Products Safety Commission, manufacturers developed standards for safety features that include shoulder harnesses, sprocket covers, guard rails and parental control keys to prevent kids from using the product without adult supervision.The bottom line with go-karts, though, is fun. For a lot of people it means zipping around a spacious backyard or a vacant field in a go-kart capable of traveling at speeds approaching 30 mph. Chuck Brisrer, who is well known in the go-kart industry, recently left Karts International and formed his own company called Brister''s Design & Manufacturing Company (BDM) in Roseland, La.
