55
Starting riding dirt bikes at 16, got a Honda 750 at 20, then got a 1976 KZ900. Sold that around 1985 to start a family, and was away from riding until the kids graduated from college a couple years ago. Went right out and bought the 2009 Ninja 650R, and this year upgraded to the Z1000. Feel very fortunate to have never wrecked a bike or been injured during all those years of riding, but I have to add that they didn't make bikes like the Z1000 back then. My Ninja 650R was faster than the KZ900, and the Z1000 is crazy fast. It's a lot easier to kill yourself on a bike now...
