During the Malaysian Grand Prix weekend earlier this month, Autosport revealed that MotoGP would bring back concessions in a bid to hinder Ducati and help the struggling Japanese manufacturers.
The proposal was for limits to be placed on tyre allocation, testing, wildcards and engine development, among other things, with Ducati receiving the harshest restrictions and a sliding scale of severity for the other marques based on championship position.
On Monday, MotoGP confirmed the return of concessions and the parameters of how the system will work, as agreed upon by the manufacturers.
Manufacturers will be placed into four groups based on the percentage of the possible maximum points they have accrued in each window of assessment.
There will be two windows in which manufacturers will be assessed. The first is from the first event of the season to the last, and the second is from the first event after the summer test ban to the last event before the summer test ban the following season.
The rankings a manufacturer will be entered into are as follows: A, B, C, D.
A manufacturer in rank A will have to have scored at least 85% of possible maximum constructors' points to be classed as such, and will then have 170 test tyres, private testing with test riders only at only three GP circuits, no wildcards, a maximum of eight engines per year and a freeze on development as well as only one aero update per year.
For a B rank, the points percentage must be less than 85% but greater than 60%, while for C it must be less than 60% and greater than 35%. For D rank, it's less than 35%.
B and C-ranked marques will be subject to the same testing limits, engine number, development freeze and aero updates as A rank, but can have three and six wildcards respectively.
They will also have 190 and 220 test tyres.
For D-ranked manufacturers, they will be permitted to 260 test tyres, testing at any GP circuit, six wildcards, testing with race riders and a maximum of 10 engines which can be freely developed and two aero updates per year.
If a manufacturer changes rank during the second window mentioned above, the concessions will be adjusted accordingly to reflect this.
For the 2024 season, Ducati will be A rank, KTM and Aprilia C rank, Yamaha and Honda D rank.
