The statement that Ducati is "only" suitable for Casey Stoner in MotoGP is not accurate. While Casey Stoner achieved great success with Ducati in MotoGP, winning the World Championship in 2007, it doesn't mean that Ducati motorcycles are exclusively suitable for him or that they are only suitable for a specific rider.
Motorcycle racing, including MotoGP, is a highly competitive sport where many factors come into play, including rider skill, bike setup, team support, and various other variables. Casey Stoner's success with Ducati can be attributed to his exceptional talent as a rider, his ability to adapt to the bike's characteristics, and the efforts of the team in developing a competitive package.
It's important to note that different riders have different riding styles and preferences. A motorcycle that suits one rider may not necessarily suit another. Ducati motorcycles have been ridden successfully by multiple riders in MotoGP, including Jorge Lorenzo, Andrea Dovizioso, and Johann Zarco, among others.
In recent years, Ducati has remained a strong competitor in MotoGP, consistently challenging for race wins and podium finishes. The notion that Ducati is only suitable for a specific rider is an oversimplification of the complexities involved in motorcycle racing and the diverse range of rider preferences and abilities.
