I'm an old guy also, 61 and I just bought a new 2012 ZX-14R. Doing the standard mods, steering stabilizer, Brock's Ti pipe(< 9lbs!!), Power Commander V, Ohlins forks and rear shock, brake lines, Brembo master cylinder, raised the clipons 1.5" with LSI hardware, and just ordered Corbin peg lowering kit.
I get to ride most of the year here in Texas and this bike is absolutely, insanely fast and I am having a ball with it. I'm going to try a track day and see if I like doing track riding.
I am pretty new here also, but it seems like a great group and I have learned a lot about the bike and options by reading everything I can.
