Get what ya like, I got the 05 as my 1st bike & love it. As long as you know your limits & stay with in them, you should be fine.

 

This question is hard to answer because I think it has more to do with the rider than the bike. For some, I think starting with a CBR is absoultely fine but for others I would not recommend it. At age 28 I started with a brand new 2005 f4i and I was absoultely fine but if I started with that bike when I was 19 years old I probably would have gotten myself either killed or crippled. It's going to depend on your maturity level and the time and patients that you're willing to dedicate to learn how to ride.
