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 En💫ea Bastianini, and Pramac’s Jorge Martin and Franco Morbidell, will profit from the new GP24.

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

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

He identified the key change as “power”.

Barana exp♚lained: "Reach 370 km/h? No, it will be noticeable in very few km/h.

“To achi💮eve alm💧ost ten km/h, dozens of horsepower are needed.

“Furthermore, top speed depends on power, but also on aerodyn🌠amics.

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

“But there are other things, that's why yওou have to rea𝓀ch a balance.

"Then, we will have an aerodynamic package, w🌳hich, as usual, we will take to Sepang.

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

“The diffe꧑rence will be visible. The differences are quite clear.

“In the simulations, on paper, it gives us good results and it has to be confirm🅺ed𒁏 on the track by the riders, at the level of feeling.”

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

He wi🔯ll join every other MotoGP rider in testing his new machinery at the Sepang test on February 6-8.

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