Nope, they're not the same. I have a 7500 FX (not my first bike :-) . I can't remember all the differences... some of 'em have suspension and others don't, tires might be different...
... but I would recommend *riding* the bikes and seeing what it feels like to *you.* While you will change some in how you sit and lean as you learn to ride more efficiently, if it feels good now, it should keep feeling good.
