As a dedicated MotoGP enthusiast, I've noticed that a majority of the racers tend to be Spanish and Italian. I believe this is because both countries have a rich motorcycling culture and a deep passion for the sport. Additionally, they provide numerous opportunities for young riders to develop their skills through well-established racing academies and various national championships. Furthermore, the support from local fans and the presence of legendary riders from these nations inspire the younger generation to pursue a career in MotoGP. Overall, the combination of culture, infrastructure, and passion has led to the dominance of Spanish and Italian racers in MotoGP.
