Zorro,
I agree, the set up of the bike plays a large roll in handling/power.
But, I didnt mention anywhere in my post about the zx7r.

I was generalizing in my previous post. Im not saying that every single smaller bike out there will handle better than every single big bike.

There are many variables that will determine that. Like you mention the set up...but then theres also rider ability also.

You say you "know" that the 7 handles better than the 6 and the 9....but for what ridder? Nicky Haden or Joe Schmoe?

Also, please use some punctuation. Im not too clear on the whole RC51/zx9r statement.
