If you're looking at terrain that requires knobbies then I'd say you're looking at the wrong bike. The FZ will most likely get you there, but it won't be the most fun and will be quite expensive to drop it. I've done fire roads and some desert road exploring, but that is probably as much as I'd ever want to do on the bike.
The big cons in my opinion:
Power - The FZ makes decent power above 8k, not really where you want it for off road.
Metal - The FZ has a lot of unprotected metal on it, and metal is expensive to replace compared to plastic.
Suspension - It's not set for ruts or off road beyond typical fire roads and gravel roads.
Could it be done? Sure. Should it be done? Matters how much money you want to throw at it.
For the cost of frame protection and tires for the FZ you could probably buy a used KLR or DZ.
If you're serious about dual sporting, I'd say have a multi-bike stable...like me
My other red bike with a plate will take me places I'd never take the FZ6.
Then again, I have ridden a full dual sport ride with a guy on a Royal Ensfield and he went every where we did, including stream crossings. Only had one issue that was fixed with tape. :rockon:
