No Race Replica 600 is a good bike to start on. New 600s are wicked powerful and put out the same horsepower to the wheel as older litre bikes except they weigh much less.

All the 600s are very similar. The GSXRs are known for having a lot of their power towards the top. I haven't liked them and prefer the power curve of the CBRs. I haven't been on a R6 but heard they have a great power curve even though the CBRs power curve is more street oriented.

Plus R6's have a history of having the tanks catch fire from crashes (which is more likely for a newbie).

I'd recommend getting a used bike above all. My first bike was a 1994 Yamaha SecaII that I picked up for $1500. Nothing fast but a fun bike and a good one to learn on...
Here is me racing a 350z. As you can see nothing great but again being a newbie you are going to make mistakes (Such as my gear selection)

After a few months or riding and putting on roughly 4k miles I sold the bike and bought a 1996 CBR600 F3 that was basically in peices. I rebuilt it myself and also got it dynoed. I got 77.89hp to the rear wheel on a Factory Pro dyno. It was running way rich and once I change my jets I shoul get about 85-90hp to the rear. Again new bikes are putting down 110-120 stock. But here is video of me running it. It can get up and move. Plus I love passing people on bran new Litres in the mountains on my ragged out bike. Not saying I'm super fast but I seem to be faster than a lot of people who think you have to have the newest biggest baddest bike to be fast...

Bikes I recommend are the GS500s or even the SV650s which are great beginner bikes you'll never get bored with. Don't believe me. Here is a SV1000 and a SV650 at Deal's Gap.
