No
I was just wondering why some people think that 620's are some magic race machine and rule the world and that you're a better rider if you race a 620 and not a 583, coz they're old and rubbish right?
Maybe we should write a whole new set of rules, just for the 620's and then we can ban the 583's altogether.
Let the rich boys play by themselves.
Oops, there I go again
