The TT Assen is the halfway point of the season, and it’s the only one of the original World Championship races (1949) still run today. According to the Brembo technicians who work closely with all the MotoGP World Championship riders, the TT Circuit Assen is not very demanding on the brakes.
On a difficulty index scale of 1 to 6, it earned a 2 - the lowest of the European tracks and higher only than Phillip Island. Assen has a maximum speed of 310 km/h (193 mph) but, thanks to the many fast bends, the braking systems are really able to cool down. And it’s precisely the presence of so many bends that makes it the best test-bench for the Marchesini rims.
