I just got my Givi top box on and rear axle spools. I love having secure storage. This is the 34 liter box.
The Top box comes off in 15 seconds..I have debated whether or not to get a top box for mine. I love the simple roadster feel of it now, but I would like more storage. I have already decided to add a 2nd bike down the road with sport/touring in mind. Might have to try that Corbin seat though. I love what you've done with your FZ07.
