So I have the opportunity to pick up a 2006 cbr f4i. The price is for $5499 has 4300 miles on it and not a scratch on it. I would trade in my fz6r and get around 4-4300 for it. So really I'm only looking at spending aprrox $1500. I was going to install a tbr exhaust and power comander on my fz6r this summer but for the price of the exhaust, $500 more I get a much faster bike. The f4i also has cheaper insurance than say a 600 SS, I would only be paying $140 more a yr for insurance. I love my fz6r but I want something with a little more juice. So since you guys always have useful information I was curious what you guys thought about it. Thanks!
