checked the FIM website. More MX classes for 2010 MX1 MX2 MX3 and now for some of the world rounds UEM 125 2T class and UEM 150 4T classes,,,,, to give the young people a stepping stone into the GPs, very cool to see especially a 125 2 stk class to the governing body to fill the need for more inexpensive more privateer friendly classes in an international championship setting.
