CodenameAcura..... here's my advice. I think you made a good decision going with a 600 because like a lot of the guys mentioned, it will help your learning curve. However, I would recommend getting a used bike for your first bike, then after you've become completely comfortable on it, you can decide whether the 600 is for you or if you want more power. Then you can go get a new bike. You'll save A LOT of money on the 600 by doing this and also you won't have to rely completely on the advice of others. If I'm not mistaken new 600s start at around $8k before tax, but you could get a bike that's just a couple years old for around $4-5k. Normally if someone asks what bike to start out on I usually say 600... but with your riding background you will more than likely be able to handle a 750 just fine which is one reason why I think it would be really benificial for you to get a used bike and decide for yourself what is right for you.
