"A supermoto could do it, but my SV would do a better job than the SM possibly could."
Ever ridden a SXV550, more HP and a 100pounds less weight.
While I appreciate the effort, race bikes should not be brought into this discussion. But I'll bite anyway.
There are various bikes out there that are ideal for various applications. An R6 makes a great track bike, for example, but is hardly appropriate to take off into the woods and run hare scrambles.
Every bike is a compromise in some way or another. Supermotards are fantastic bikes in specific conditions where other bikes may falter. Vice versa for the aforementioned R6.
I think many riders would agree however that the vast majority of roads are ridden between the speeds that I mentioned in my previous post - 40 to 85 mph or so. Laws can be broken in any given situation. Most riders try to keep it reasonable in order to hold on the their precious licenses.
A supermotard is a shitty bike if it spends all day long above 70mph, and as such can't be considered the least bit decent for long distance serious travel. The problem with those super tight twisty roads is that there is usually some travel to do in between. A lot of guys end up buying something like a DRZ only to turn around and sell it a few months later when they realize that it isn't exactly what they were looking for. Anything above 60-65 is painful. Sure, it can be done.. but there's a tool for every job, and a supermoto isn't ideal for making a lot of time fast.
I proposed the idea of a middleweight sportbike / similar as an ideal compromise. Many of us have learned that it is fun to ride a slow bike fast, but not nearly as much to have to restrain yourself with a fast bike while riding slowly.
Perfect solution? Voila. The middleweight.
The supermoto does
some things better, but
not as much as a middleweight sprotbile with bars. As much as you would like to argue, most riders would be better suited with the above Street Triple than they would with a supermotard. That said, I still love supermotos.

But just make sure that it isn't your only bike.
