The main difference between the two generations of the F3 Pro Max is the size of the brake discs. The first generation was equipped with a two-piston brake system and 180mm discs, while the second generation featured a four-piston brake system with larger 203mm discs. This is the difference in braking performance and overall stopping power between the two generations.
