To put this into perspective, a washing machine spinning at 1500 rpm only makes 25 rotations per second. Moving on to other components, the wheels of the motorcycle can exceed 50 rotations per second at a speed of 300 km/h.

Being constantly subjected to such accelerations and decelerations puts a lot of strain on the pistons. It does not seem like much, but we are talking about an average speed of a part that travels approximately 48 mm, in which it goes from being completely stationary, to its maximum speed and then braking to a halt. The pistons move at an average speed of around 29 m/s (meters per second), slightly quicker than 100 km/h. The injectors that feed the engine follow the same rhythm as the valves, performing about 9000 fuel injections per minute when the engine is at maximum capacity. The demand that this movement has on the parts means pneumatic valves are necessary, since conventional springs are not guaranteed to withstand this intensity. At such speeds each valve opens and closes 150 times per second, something difficult to imagine. The engine moves at 18,000 rpm when the rider demands maximum power. The MotoGP bike’s engine for example, has many moving parts that move at different times and in different ways. There are other speeds that are not measured as much, and are not seen, but are equally as important when driving one of these vehicles. At the moment a MotoGP bikes usually travels at average speeds of between 160 and 185 Km/h depending on the circuit and the conditions, and Dorna shows us at what speed a certain pilot is travelling at, during the race.
