MSMA are considering an 850cc engine limit. KTM and Aprilia are against it.

Thinking out aloud [that's what happens when you post after consuming red wine] what exactly is the issue with the current bikes, is it the speed they get to, is it the acceleration, is it the corner speed? If its the corner speed what about making the tyres slimer?
 
There are so many moving parts to the top speed equation, and capacity plays a small role at this point. My feeling is that this 850cc idea was floated in conjunction with ride height devices. In other words, if ride height devices stay (please no), the engines will be de-stroked to reduce the torque put to the ground through the rear wheel. This would make the ride height devices less potent and reduce trap speeds and top speeds.

It's also possible that several manufacturers think the rev ceiling is not spectacular enough for MotoGP, and ride height is not involved at all. The manufacturers in favor of 850cc might be tired of designing bikes around the incredible excess torque of the 1000cc 81mm engines, and they want to de-stroke and get back to a more classic bike design with higher rev ceiling. Aprilia and KTM would unsurprisingly be opposed since they don't have GP experience with high rpm engines or cornerspeed style bikes.

I think if they get rid of the aero and devices crap top speeds should decrease a bit because the bikes will no longer be on rails.
The racing they should seek to recreate is the racing we saw from 2016-2020 imo. Pretty much every race was awesome back then, you'd see riders trying to pass in almost every corner, nowadays they need a long straight to draft.

So Gigi gave an interview to Speedweek recently and he's saying all the wrong stuff. I disagree with almost every word he says, what he's suggesting is gonna make the racing even worse than now.

First of all he says that it's impossible the MSMA will agree on all details of the new rules so Ezpeleta will have the last word. Whether or not that's a good thing remains to be seen.
Gigi also says it's not a problem that there are no street bikes with 850cc "cause we're building prototypes".
He is strictly against banning devices because "then we might as well remove the wings from F1 cars because everyone has got them". According to him the wings are safety-relevant because the most problematic phase when steering a motorcycle is whenever the front wheel isn't touching the ground.
He doesn't care that riders complain about dirty air because according to him these turbulences already existed in the pre-winglet past.

This guy should be taken to a dark room and be beaten.

Gigi Dall'Igna (Ducati): «Der Top-Speed ist zu hoch»

Gigi Dall'Igna verrät im Exklusiv-Interview, warum er den MotoGP-Hubraum auf 850 ccm senken und bei den Devices und Winglets nichts verbieten will. Beim neuen Reglement rechnet er nicht mit Einstimmigkeit der Werke.

Well, no surprises here. The 850cc capacity proposal is an attempt by Ducati to retain ride height, aerodynamics and 81mm bore. Sad, but sadder still, there are some rumors that Ducati want ride height to be used like DRS in F1. In other words, it will be a push to pass or a GPS controlled system to aid the trailing rider.

Honda and Yamaha probably support 850cc because both manufacturers support the cause of controlling bike performance with engine displacement.

I don't recommend physical violence against Gigi, but I do think he needs a lifetime ban from the sport. The Japanese execs who put through the 21L 800cc formula are long gone, and Gigi is just a one man wrecking ball, on a mission from VW to liquidate MotoGP and WSBK to increase Ducati's spin-off valuation. In Gigi's defense, the Panigale V4R appears to be built to the WSBK rules--no lawyers required--that might be a first for Gigi? or maybe he's not really involved in WSBK at all?

In a nutshell it works like this, if a feature gives you a competitive advantage over the other manufacturers then it is supported. If a feature gives other manufacturers a competitive advantage then it must be banned

In regards to the aero in addition to the turbulence there the problem that it results in the front tyre of the rider behind over heating due to less cooling.
