Yamaha's KT100S and KT100J kart racing engines have been a major part of Australian kart racing for more than 20 years.

The KT100S is the most popular high-performance 2-stroke kart racing engine on the track. KT100S classes, such as Clubman, offer the most competitive racing at a cost that makes racing surprisingly affordable. The Clubman classes use the high quality, durable and economical MG AZ-Red tyres.

The KT100J is used in National classes, as well as in Midgets and Rookies in a restricted format, offering kart racers the most affordable option for entry level racing.
