"- if a rider of a 1000cc 4 cylinder is leading the riders' Superbike World Championship standings at that time, then the initial air restrictor size of the 1200cc 2 cylinders will be increased by one size, to a Ø 52 mm (or the equivalent area 2123.7 mm2), or as a last step, without any air restrictor.
"2. - If the minimum weight for 1200cc 2 cylinder configuration has reached the upper limit of 171 kg and,
"- if the resulting gap of the average value of 'event averages' is more than 5 points in favour of the 1200 cc 2 cylinders and,
- if a rider of a 1200cc 2 cylinder is leading the riders' Superbike World Championship standings at that time, then the initial air restrictor size of the 1200cc 2 cylinders will be reduced by one size, to a Ø48 mm (or the equivalent area 1809,6 mm2), or, as last step, to a minimum of Ø46 mm (or the equivalent area 1661.9 mm2).
"If the air restrictor size is not updated, then the results of three more events will be considered, and a new average value of the 'event averages' will be calculated over six events and so on, over multiples of three events, until the points gap of the average value of the 'event averages' from the last air restrictor size update is higher than 5."
