In my humble opinion the F3 does not look as sweet as the earlier F4, and the increase in power and handling would not make one jot of difference to a mortal like me. I did have a sit on an F4 a couple of years back, and about one minute was enough to convince me that, while I might look good on one, I could not possibly ride one. Anyhow, where do the panniers go? Where does the "dearly beloved" sit? There's no way to fit a top box!! Where can I fit the GPS which would need to be pre-programmed to find the nearest physio?
