Ok, somehow I got lost here...

250 Superstock:
The class rules will remain the same as its predecessor ESS. The only addition will be that F4 machines will now be allowed in 250SS.
So now F4 is not going to include the baby Ninja or any of the bikes that formerly ran the F4 class?

That doesn't make sense when you say this:

If the EX250 can't run F4, why is it important to make a "true F4" bike more competitive with the EX250?

Also now my Aprilia RS125 is only going to be legal for the 250 class to race in? To me, and probably only me, the RS125 is the perfect bike for F4 and then can race up to the 250 class.
