Only reasoning is a 150/60-17 rear tire.
the ninja 500(3.5-17) wheel is a full INCH wider & taller then the 250(2.5-16)
I also think it will make my wheel base a little longer
Plus Regardless if i swap or not i will put a GSXR 600 Piggy back shock in
Imagine This

With Clip ons, Woodcraft rearsets, Airtech SS tail and a Michelin 150/60-17 rear tire!
And an ungraded suspension to handle the turns(and sitting a little lower)
