Wonder if that will give KTM, and Aprilia a push to put their GP V4's into the next gen street bikes. As the engine size and fuel is to be changed...?
--ENGINE: Displacement reduced to 850cc. Max bore reduced from 81mm to 75mm.
--FUEL: 100% synthetic (non oil refinement derived) fuel, up from the 40% requirement this season. Max fuel load reduced to 20L from 22L, and 11L for the Sprint race.
--TRANSMISSION: Number of gearbox ratios (pairs of gears) permitted will reduce to 16, plus 4 different overall ratios for the primary drive.
--SUSPENSION: All ride-height and holeshot devices will be banned.
--ENGINE SUPPLY: Reduced to 6 for a 20 race season, and 7 for a 21-22 race season.
--AERODYNAMICS: Front end max width reduced by 50mm and pushed back 50mm.
--WEIGHT: Minimum bike weight 153kg.
--DATA: All teams will share GPS data.
--CONCESSIONS: Revised to four levels that will be adjusted mid-season. New teams that have not raced in the prior year will be given the highest concession level, Rank D. All other teams will start the season at Rank B.
