Sevlievo and the Grand Prix of Bulgaria witnessed the opening round of five in the inaugural FIM Women's World Championship and Yamaha Van Beers Racing's Katherine Prumm battled adversity to take fourth overall. The double World Cup winner was not afforded a fair debut on her YZ250F after rupturing her right anterior cruciate ligament in the days leading up to the Grand Prix. Putting aside her pain and discomfort it was an uneasy weekend for Prumm who tried to compete but was clearly frustrated by the handicap and being unable to run at her normally impressive speed.
