I am 63 and own a 03, love it and can't wait for the next big busa. I thought it might have come out for 2012 but maybe next year! I have owned fast superbikes since the first kz900 kawi, cbx, ninga 1000r, zx1100. This one is the best of all worlds, comfortable for long rides, 400 mile day trips, and fast enough to totally respect it! I think 60's will be no problem, 70's maybe,80's............ not worried; it's to far away. have fun.
