Engine: Any of the above engine types can be used, however if you are looking for the ultimate in reliability then this is where we can talk about gearbox powerplants. The most readily available are those fitted to motorcross bikes manufactured by any of the Japanese manufacturers. The Yamaha YZ125 or Honda CR125 are my preferred engines which can be purchased from Metropolitan Motorcycles at Silverwater. A late nineties model will cost around $1800. A tailor made pipe will cost around $450 so for around the same cost of a Rotax you can build a kart that is a lot more fun to drive and a lot less hassle and cost to maintain. All Italkart Senior chassis are manufactured with shifter stick mounting bracket for the US market so can be easily converted to gearbox configuration.
