TUV in Munich, Germany are possibly the only company in Europe that have developed a specific test procedure for kart catalysts. A kart is strapped to a set of friction rollers and 'driven' through a series of cycles representing acceleration, deceleration, idling and flat-out running. All of the exhaust gases are collected, analysed and weighed. This procedure gives a very accurate picture of overall emissions in real life conditions. In November 1998 our Top-Mount Kartalyst (TMA) was tested by TUV while fitted to a kart with a Honda GX160 engine. The results show that all emitted gases were reduced by a minimum of 62%:

TUV Emissions Test Results for Top Mount Kartalyst (TMA)


By using the TUV tests as a world class benchmark, other emissions tests have been carried out on our range of Kartalysts. Using a belt-driven generator to provide the load on the engine, and a garage type 4-gas analyser, CO emissions were measured on a Honda GX200 and GX270 Engine:


Test Results for a Low Mount Kartalyst (LMA) Fitted to a Honda GX200 Engine


  • Our Low Mount Kartalyst obtained a minimum CO reduction of 72% at 5000rpm. The maximum reduction was obtained at 3000-4000rpm of 99%.


Test Results for a Top Mount Kartalyst (TMA) Fitted to a Honda GX270 Engine


  • Our Top Mount Kartalyst obtained a minimum CO reduction of 58% at 5000rpm. The maximum reduction was obtained at 3000-3500rpm of 99%.



We have highlighted the type of gases emitted from kart engines, the dangers of over-exposure to these gases, current karting regulations and finally, how you can reduce these emissions by fitting our Kartalysts. For more detailed information about our kartalysts, please see our two product sections; 'GX120/160/200' and 'GX240/270'. If you require more information about the catalysts used in our Kartalysts, please see our 'Catalyst Info Section'.
