Marc Marquez’s Ducati this season🗹 will lack the developments that will be added to four of his rivals’ bikes.

Factory Ducati pair Francesco Bagnaia and Enea Bastiani﷽ni, and Pramac’s Jorge Martin and Franco Morbidell, will profit from the new GP24.

The Marquez brothers at Gresini, and VR46’s Marco Bezzeccꦡhi and Fabio di Giannantonio, must ride a year-old Desmosedici.

Ducati technical director Davide Barana told how the newer version will be more advanced than Marquez’s: “"I think the difference between GP24 and GP23 will be highe♛r than that between GP23 and GP22.”

He identified the key change as “power”.

Barana explained: "Reach 370 km/h? No, it will be noticeable in verꦛy few km/h.

“To aꦺchieve almost ten km/h, dozens of horsepower are needed.

“Further🐲more, top speed depends on power, but also on aerodynamics.

"If you have a 🎉lot of surface area to make downforce, 🎃it will cost you more in top speed.

“But there are other things, that's why you have to reac🍰h a balan🌳ce.

"Then, we willဣ have an aerodynamic package, which, as usual, we 🍎will take to Sepang.

“In the presentation we saw the aerodynamics of the previous year... also because we have few parts🌳, we always arrive at the last minute.

“The difference will be visible. The diffe𒉰rences are quite clear.

“In the simulations, on paper, it gives us good results and it has to be confirmed on the track by the ridersౠ, at the level o💎f feeling.”

Marquez tested a GP22 at the postseason Valencia test, his Ducati🦋 debut, last year.

He will join every other MotoGP rider in testing his new machinery at the Sepang t🐭est on February 6-8.

Honda and 𒀰Yamaha riders will 💖have a head-start, and be allowed to test at the shakedown on February 1-3, due to the new concessions rules.
