One of the race tracks designated as a “hard” braking circuit is the Catalunya circuit and it features seven braking zones. Many of which require substantial braking effort before the turn, which puts maximum stress on the braking system. Adding to the stress is a rather technical course layout. This means the discs and pads don’t have much opportunity to cool before being put to use once more.
Despite these challenges, none of the riders complained of braking issues throughout the race, where they spent 23% of the lap decelerating. Over the course of the race, 6.2kWh of energy is produced, which is marginally more than the capacity of a Zero FX. Here is the full-size graphic below for more interesting information.
