Being based in Germany, all motorcycle manufactured by BMW are subject to European Emissions Standards (EURO Standards). Despite being a few years behind those regulating cars, emission standards for motorcycles are quickly catching up and becoming increasingly stringent.
EURO 3 Standards currently cover motorcycle emissions and these specify the maximum permissible emission of carbon dioxide, hydrocarbons and nitrous oxide. The values of these are 1.0, 0.1 and 0.08g/km respectively.
It is proposed that motorcycles will comply with EURO 4 Standards by 2012 and EURO 5 Standards by 2015. This will reduce emissions by around 50 per cent in 2015, bringing the standards for motorcycles in line with those regulating cars produced in Europe.
The requirement to have a motorcycle tested on a regular basis varies depending on which country it is registered in. In the UK, for example, motorcycle emissions are not tested. In Germany periodical testing is mandatory. In the U.S. test periods vary from state to state. It is expected that growing concerns over climate change will result in a greater level of uniformity in motorcycle emissions standards.
