Sold my Busa about 4 years ago. Had 06 Busa. Now have C109rt cruiser. Considering getting Gen 2. Besides color changes, little better brakes and ABS in 2013, what has changed from 08 to 16? I rode a buddies 08 about 4 years ago and really liked it. Is it worth paying more for a new or newer Busa vs 08 to let's say 2010?
