Eric,
Thanks for the info. Chances are the only expenses I'll ever incur will be maintenance/repairs, because if my sportbike history is any indication, mods are wasted on me. My skills will never exceed the capability of a stock bike, let alone a modded one.
Actually, that might make the 95-or-less HP of a 748 a better choice for me.
I'll let you know if I make any progress!
