Don't get me wrong, I respect the smaller bikes & everybody has a choice but don't tell me if you put 2 persons of similar skills on each of those bikes, the 300 will come out on top all the time
Not any time. If you turn the same lap times on a 600 as you do on a 300 you need to stay on that 300 until you learn some stuff.
The guys on the big bikes in the video are obviously new track riders. Pretty dumb comparison.
