On the long distance touring front, how does the Discover 125T Disc stack up against purpose built tourers?

While mostly a commuter motorcycle, some Discover 125T Disc owners have used it for longer rides. It's triggered debates as to its suitability for touring. It's not designed as a tourer, but it's comfy enough to sit in and its fuel economy is decent enough for budget conscious travelers. But it lacks such features of a dedicated touring bike as a big fuel tank, protection from the wind, and luggage space. A few riders argue that with some modifications — such as a windscreen and luggage rack — the Discover can make a capable tourer. Others say that given its limited power output and basic suspension it is not fit for covering long stretches on the highway. It is often discussed in terms of cost, comfort and capability trade-offs that those who are thinking of using the Discover 125T Disc for more than just daily commutes have to make.
