The Yamaha KT100 engine has been the main stay of New Zealand Kart racing for over 20 years.
Kiwi Karts have gained a vast knowledge and experience with these engines with many Championship wins to their credit. With 13 piston sizes and a full range of original replacement parts available a new engine has a potential racing life in excess of 13 years. This in combination with Yamaha’s proven quality will see the KT100 continue to be the engine of choice for our Karters well into the future.
