My first bike was a 1985 Honda 500 Interceptor that I thought would be as much bike as I would need for a long time. After about 3 months I was ready for an upgrade, but I was stuck with the bike I had until I could afford to sell it and buy something else. While I agree with the theory of starting out on a small bike and working your way up, for the minimal difference in price, I would get the 6-speed version so that when you get accustomed to riding, you have the tools at your disposal to enjoy this bike longer. Therefore you won't be trying to trade up 6 months after you buy the bike. The 620ie has so much room for improvement that when you're ready for more power, it will be easy to get without having to trade it in, and having the 6-speed with the slipper clutch will allow you to enjoy the bike that much better. besides, the slipper clutch will in no way hinder your learning experience. I'm sure that if you really want the dark look you can find a tank that someone would be willing to trade for a painted one.
