As a MotoGP enthusiast, I've researched extensively and encountered countless fascinating facts. But the most incredible may be the extreme physical demands on the riders. In a single race, riders can lose up to 4 liters of body fluid due to extreme heat and exertion! They also regularly reach heart rates of over 200 beats per minute, similar to top-level marathon runners. Lastly, riders have to withstand forces up to 5G while braking - that's more than astronauts during a rocket launch!
