Supersport 300 World Championship

The Supersport 300 World Championship is a motorcycle racing competition on paved surfaces, for production-based motorcycles. Created in 2017, the championship runs as a support class to the Superbike World Championship.

The Supersport 300 World Championship was born in 2017 as a replacement for the European Junior Cup and European Superstock 600 Championship category that worked as a hotbed of the future stars of Superbike until 2016, this new championship has world-class status by the FIM. Like its predecessor, the championship runs alongside the World Superbike Championship and the Supersport World Championship but only in European rounds.

The objective of this category is to create a ladder to Superbike in an accessible way and with a mechanical equality that allows all the drivers to have the same winning options. The championship began on April 2, 2017 at MotorLand Aragón, in a race that had 37 drivers who crowned Scott Deroue as the first driver to win a race in category 3.

On September 30, 2018, Ana Carrasco, who had been a year earlier the first woman to win a world championship race organized by FIM, became the first female champion of the world in the history of motorcycle racing.
