While i like the idea of a Ninja 250 cup or the 450 series. Im not sure how this helps our current situation of the lack of racers showing up.

Seems most new racers turn their street bike into a race bike or purchase a bike that is already in race trim. The 250 cup is cool and would be hella fun if there was 15-20 others to race against. I dont think most people would buy a bike that would only be competitive in one class.

The 450s are bad ass indeed but not exactly inexpensive to build. Also depending on who you talk to they can be expensive to maintain.
