Well, if you had a 900 before the CBR600F3 has better handling and should be a good upgrade for you. If you drop a tooth on the front sprocket you will have no problems lifting the front wheel in second gear. I have already heard the stories of people that have tried this and the bike came out from underneath them. As we all know, once you lay the bike down and get a few scratches the value of the bike goes way, way down. The engine pulls very strong all the way up to the red line (13000RPM) but I have never attempted to rev it up that high. It tops out at about 150MPH but who in their right mind would take it up to that.
