At the same time it was decided to set the minimum weight for the 600 Supersport championship machines to 161 kg across the board. Currently the rule requires 675cc three cylinder machines a minimum of 162 kg while 600cc fours were allowed to be lighter, at 158 kg and 750cc twins were given a mimimum of 166 kg.
Although Ducati has contested the Supersport class in the past with 750cc twins, there are currently no twins in the class.
Both changes - to the Superbike and Supersport classes - have been made with the aim of reducing costs by, in the intention of the Commission, making the use of precious and expensive materials unnecessary.
