I have recently stumbled upon a deal of a life time. Someone gave me a 2011 GSXR1000. Clean title, never been down, 4500 miles. As I do not want a GSXR I was going to trade it in. My choices are either a Repsol CBR1000RR RC211, a 2010 R6, 2010 10r or if I can fenagle it, an 05 Aprillia RSV4. Which should I choose. Mostly street riding with the occasional weekend 25MPH corner at 75, and maybe a couple of track days a year.
