Hello all. I understand the questions of how to start racing have been beat in the head to death but I still have some of my own. I currently am riding an 18' ZX10R and I have done some trackdays and I ride often on the twisties but it's getting old. I love my bike but I don't want to risk binning a brand new bike on track. I'm looking for a track/race bike in the $4000 range. My question is if I were to pick up an older 600 for the $3500 range would it still be competitive racing? I understand talent plays a big factor but assuming I'm at a level to be competitive will an older bike have a chance? Are bikes from the mid 2000s era still competitive? What is the timeline for any vintage classes? Are the newer bikes with all the electronics transforming the field of novice racers? I feel very comfortable on my 1000 but don't think I could afford the tires let alone laying it down. Quick background. I have raced my entire life starting from 14 years old racing MX, then flat track, and then after some broken bones dad said no more of this and then I started racing dirt cars eventually getting into sprint cars which I raced for about 8 years. Racing is in my blood and can't wait to join the motorcycle family of racing! I'm 32 years old and I'm just looking to have some fun next season, learn as much as possible, and see how it goes. Thanks in advance all.
