The greater the distance covered in an endurance race, the less chance the competing teams will be able to do as well or better and dominate. But to cover a greater distance as everyone who uses a motorbike for traveling knows, you must reduce stops as far as possible, either making less and/or reducing how long they last.
This is where Brembo comes onto the scene with a series of studies to find a solution that reduces pit stop times without compromising on the quality of the motorbike chassis. Brakes are unsprung weight and therefore the smaller they are, the lower the negative effect on braking as well as on acceleration and changes in direction.
On the other hand, though, an undersized brake system would not be able to offer all the braking power that these motorbikes need. Alternatively, it would only guarantee a lower number of braking episodes because the undersized discs and calipers would lead to overheating or the friction material would be completely consumed.
