I've had several dirt bikes growing up and as an adult (I'm 40 now), 3 GSXR 750's (1989, 1991, 1996), CBR900RR, and a few more not worth posting. My two favorite bikes are not listed above, pics below. These were my last two in this order...
1998 R1 - I had for 5 years...
2006 Z1000 - I only had for a year before my son was born and my wife suddenly didn't want me riding anymore... :(
Family means more to me now, but I sure do miss riding...
