A ninja and a sportbike are two completely different things:
Ninja: A ninja is a historical and cultural figure associated with ancient Japan. Ninjas were highly skilled covert agents who practiced ninjutsu, a form of unconventional warfare and espionage. They were known for their stealth, agility, and mastery of various martial arts techniques. Ninjas were typically trained in espionage, sabotage, guerrilla warfare, and assassination.
Sportbike: On the other hand, a sportbike, also known as a sports motorcycle or supersport, refers to a type of motorcycle designed for high-speed performance and nimble handling on paved roads. Sportbikes are built with aerodynamic styling, lightweight frames, and powerful engines. They are specifically engineered for rapid acceleration, precise cornering, and high speeds. These motorcycles are often used for racing, track days, or simply for enthusiasts who enjoy the thrill of riding fast.
In summary, a ninja is a historical figure associated with ancient Japanese warfare and espionage, while a sportbike is a type of motorcycle designed for high-speed performance on paved roads.
