Horstman Manufacturing was founded in 1963 by karting legend Gil Horstman.
Gil first became involved in the sport during its formative days in the fifties.
Karting originated in Southern California where Gil and fellow enthusiasts took their prototype
vehicles to local venues like the Rose Bowl in Pasadena or the Eastland Mall in West Covina
to test and show them.
Kart clubs and race rules were soon in place and karting grew quickly around the globe.
Although Gil was an accomplished racer he preferred to help fellow karters win with his modified 2 cycle engines.
Gil sold his tool & die company in 1963 in order to devote all of his effort into supplying
the demand for his engines and karting accessories.
Gil brought many innovations to the sport as well as leadership, dedication, and caring.
Horstman is the leader in the industry for winning products.
Horstman technical staff are current or former kart racers with over 140 years of combined experience.
