morepower wrote:250cc Super karts have been around for years.. my oldest brother used to race one in the late 70's and early 80's. Now they are using engines with loads more power than the Yamaha TZ250. I know of a couple which have been dynoed as 105 BHP !! Here is one which is 90 bHP straight out of the crate !! http://www.brceng.com/pdfs/BRC250FE_Tech_Data_Sept05.pdf

But the engines are very expensive. ZIP sell one make at £14,500 each !!

By the way they are KARTS not Go Karts or carts... The drivers get upset if you call them go karts because that is what kids build with bits od wood and old pram wheels.
