I got a little carried away at one point and had all of these at the same time:
I still have the FJR and added this:
The FJR will give you a work out but can hold it's own in the tight stuff and works great for me when riding 2up, which is mainly what I use it for.
The VFR is a great bike but the Tiger I feel is much better on the less than perfect roads I ride.
The CBR...everyone should ride one of these at least once in their life. The reason I sold it was because every time I pulled out of the garage I would tell myself "you can't get crazy' but I would always pull back in the garage telling myself, "that was crazy"!
God I miss that CBR!!
